Remington 1100 Gas Seal Replacement

The Remington model 1100 semi automatic shotgun has a rubber o-ring that serves as the forward seal of the gas operation system.
These need to be changed occasionally. You should inspect the seal when you clean your gun. If you notice the o-ring is nicked or becoming cracked it should be replaced.
It`s an easy and simple process that requires even less disassembly than is needed to give the gun a good cleaning.

Truly a sweet shotgun. I had an 1100 with the fleur de lis pattern on butt stock and forend, scroll work on receiver and bolt, white spacer and diamond design on grip cap, 1" recoil pad, 26" improved cylinder vent rib barrel, in 12ga (2.75" only). Sold it to a good friend a few years back for $325. Didn't care about getting a great price, just wanted it to have a good home. Miss that gun.

While I agree to definitely have a replacement o ring available I doubt that saving the old one makes much sense. These rings are so inexpensive ( many are sold 3 in a pack ) that for me at least, just getting an extra one or two rings works for me. Some guys use vitron #021 rings from a hardware store which are even more economical. Good video, straightforward and easy to understand... good tip about over tightening the magazine cap for guys like me who have a habit of going " just a little bit tighter ".

[@Ez-tz7is]

You should put tape around them threads before you install the new o ring!

[@John-gy1cu]

Great idea simply put , Thanks !!!

[@Jojo69869]

oil or petroleum products will deteriorate the seal. Use silicone grease instead.

[@MyHollowpoint]

My favorite shotgun. Thanks for the vid.

[@1957Shep]

I bought this one new in 1978. I`ve never even considered selling it.

[@MyHollowpoint]

1957Shep About the same time I got mine. I had mine parkerized.

[@Killer86000]

I have one that looks just like his, left handed, and I let the bluing get a little rusty :(

[@KSFWG]

Great video ! I have a 1100, and it's forerunner, 11-48 (built 1953 - was my father's), and a Browning Gold Hunter, all in 12 gauge. I'd sell the Browning before I'd part with either Remington. :) Thanks for the video!

[@1957Shep]

I bought this one new in 78. I never did do much bird hunting, so it`s never been dragged through the brush very much. But it has busted a lot of clay pidgins over the years.

[@davidwagner4355]

Good video my uncle almost sold his 1100 because of that ring. I gave him a extra i had.

[@1957Shep]

If a Remington auto doesn`t cycle right, that seal is the 1st thing to look at.

[@SpencerShirey1998]

My dad has a 1100 it had the factory gas seal from the 70’s up until a few years ago when it finally dry rotted

[@Dave-fo1cb]

Very nice 1100 I have a newer 1100 sporting and it my best gun. One thing I would add to this great video is that you could put tape over the threads on the magazine tube when installing the o ring otherwise you may get little cuts in the o ring which will break it down sooner.

[@1957Shep]

Dave Good idea.

[@hawaiivolcanosquad3322]

Mahalo for the shout out! Looks like I may get that Benelli Super Nova after all so I am gonna have to watch all your shotgun videos to learn more. Will be my first shotgun if the deal goes down this Friday. Thanks again!

[@1957Shep]

You will have to teach me about the Benelli. I`ve never even shot one of them before.

[@Notttttttttygggtggg]

thanks for the info my o'ring fell into pieces when I pulled the barrel off

[@cyberpunk004]

if you want some spares that don't break the bank on shipping, #021 o rings (viton) from the hardware store are a good choice too. they don't quite last as long as the remington ones(they graphite coat theirs) but generally only cost here around 59 cents so just toss a 6 pack in your choke tube bag just in case. The remington ones last me around 1,000 tactical slugs(1,300 fps) or close to that for high power ones before they started looking questionable and for less than a candy bar, why take chances with it failing.

[@1957Shep]

+twilson1118 Thanks. Good to know.

[@dalereed3442]

bought my 1100 in 74..thousands of rounds, until now Ive never thought about changing the o ring...I would just oil the old one and go...still works flawlessly, but It would be a good idea to change it out.. thanks

[@yvesf5355]

great Video thank you I just bough one yesterday I can't. wait to try it out ..

[@1957Shep]

Hope you enjoy it!

[@dalejohnson9624]

Don't forget to check the gas ports they get plugged which causes the gun to malfunction

[@1957Shep]

Good point, but that should be done every time you clean one.

[@PB621]

I always put little grease (fatty acid ester) on it. Never oil (oleic acid) because an acid reacts with rubber over a longer time period.

[@1957Shep]

Thanks.

[@lukehatfield8988]

watching him put the o ring on tube reminds me of the high school days to keep from have curtain climbers with the girlfriend,,,, those things were hard to get on tooooo. lol. thanks for the info im working on a buds 1100 its not resetting the hammer. I think a good cleaning and a new o ring will do the trick...i hope... i told him i new what i was doing...lol✌

[@chuckybaby1973]

Thank you for the video, ordering my new o-rings from Amazon right now.

[@1957Shep]

Glad I could help

[@martymarfishhunt3622]

Did the rings from Amazon work for you?

[@SpecificLove7]

Nice to see you have a How-to video

[@1957Shep]

Should have done this video when I changed out the seal on the other 1100. That one needed it badly. Would have been easy to see how the seal in the other one had dried out and cracked.

[@jlc904ubc]

Hi, Shep. I just subscribed. Bill Goudy sent me.

[@derroncook1402]

Bill goudy is the man!

[@dedmotorhed]

Don't forget to clean the small gas ports

[@78tag]

Most people doing these videos neglect to mention that point. Considering the importance of those ports to the operation of the gun I'm amazed that most don't about it.

[@VirginianSpencer]

Hugely overhyped issue. I replaced the metal V ring with a Viton one in 1967 so I wouldn't lose that V ring. Over 100,000 rounds and 54 years later it is still in service and shows no signs of wear. They only get moved during maintenance, and roughly sliding them over those threads kills most.

[@Bikerbob59]

Thanks I was wondering if I had done it right.:) Love this gun.

[@1957Shep]

I`m hardly an expert. But this is simple enough even I couldn`t screw it up. :)

[@rls303]

Great how-to, Thanks

[@1957Shep]

Thanks.

[@pamtnman1515]

O rings are available for cheap at automotive stores. thanks for posting

[@John-gy1cu]

Wish you would have pointed out how and where to clean out the gas port holes , definitely a necessity on semi auto shotgun!

[@summerknights476]

hey Mac good video there fella .

[@cloudyskies7754]

thanks for video chief

[@1957Shep]

+tom kirk Thanks for taking the time to watch.

[@MITimberwookie]

Great instructional video.

[@1957Shep]

Thanks.

[@410mossberg]

Nice video. I have an 1187 12 gauge and make a practice of replacing that o ring once every two years - even if it isn't cracked. I don't use that gun that often and I think dry rot could do just about the same amount of damage as overuse. It's about a 20 year old gun and works fine. Maybe a dumb question, but what is the difference in an 1100 and an 1187? Weight? Thanks for a good maintenance video. I'd like to see a few more from your semi-auto pistol collections

[@1957Shep]

Like any rubber o-ring, they get dried out and will get hard and crack. Not sure what all the difference are between the 1100 and the 11/87. Seem to remember that the 11/87 has a self regulating gas system? Or an adjustable gas system? The 1100 doesn`t. I was always happy with the 1100 so I never thought much about the 11/87.

[@1957Shep]

410mossberg With a few exceptions, all my auto pistols have already been in at least one video. I probably won`t do any more range videos until I get my back fixed. Have a herniated disk. Right now it`s kind of painful just hanging around the house reading or fooling with the computer. Going to the range would not be much fun. Was supposed to have had an epidural done on the 25th, but they called today and said it would have to be rescheduled. Don`t know when yet.

[@410mossberg]

1957Shep Hope you get that back fixed. Will miss your videos. Get better. A bad back is no fun. I know from personal experience.

[@1957Shep]

410mossberg I`ve been through this before about 10 years ago. That time I had to have surgery. Hoping I can get by without surgery this time. I`m still going to try to do a few videos. Just not shooting videos. Right now it just hurts too damn much to be on my feet for very long at a time. Some days are better than others. Some days it`s pretty painful no matter what I do or don`t do.

[@Gunsandfun1961]

Alright ,...thanks for that,...

[@1957Shep]

Thanks for taking the time to watch.

[@GeorgeWehrenberg]

Would a worn rubber o ring cause my 1100 not to cycle properly? Mine does not eject the spent short brass skeet loads fully. I have never changed tthe o ring seal and bought the gun in 1963.

[@BrianFolks]

For the cost of a the ring give it a try.

[@nammie12345]

Not cycling properly is the symptom of a bad gas ring.

[@John-gy1cu]

And possibly clogged port holes !?!?

[@Marcel-Namsos]

:) Nice to know. Only have a Rem 870 pump my self.

[@1957Shep]

The 870 is a good shotgun.

[@Marcel-Namsos]

1957Shep I hit very well with it. Suits me good.

[@TheLightHouseLady]

Good video!

[@1957Shep]

Thanks.

[@richardsonger1120]

My 1100 is LH. Bought in 1984 for 500+$.

[@1957Shep]

You should do a video with it sometime.

[@phmj]

shep have you tried a orange viton oring they are much tougher than the black silicone ones they can tolerate freezing and boiling situations and seem not to dry out easily

[@1957Shep]

+megabubbar john No, I have never heard of them. Thanks.

[@Chuxgold]

Mine has a spring around the magazine that the barrel recoils on. Just what does it take to fix it from jamming. As it has no place for a gas seal. I'm confused as all the videos show them being like this one in this video.?

[@bobburnitt5389]

Being rubber or is it neoprene , I would guess this O-Ring will even decay with time alone, like siitting in the Gun safe. I know on Cutting Torches the O-Rings in them will decay simply being exposed to the AIR as the Air contains OXYGEN and I have been told Oxygen will decay rubb or surely syntnetic rubber wish is MOSTLY what we have. Most things we call runbber are actually synthetic rubber. Just a thought. Trying to keep O rings available for my torches has never worked very well. However, if I put them in a plastic bag, put a soda straw in the bag when it is almost completely zipped shut, then sucking the air out and Closing the bag completely seems to help. Also, I keep them in a cool, dry and DARK place. They will last awhile if I do THAT. Of course one NEVER "oils" anything with a cutting torch. But I would guess these O-rings are made of similar material. I have been keeping Cutting torch rings like tis for about 40 years. but they won't keep forever no matter what I do. So, if you have one been saving for several YEARS you better take a close look. I have a Remington 1100 Tac 4, I almost never shoot it, though I really like it, but it is still virgin new. BB

[@BrianFolks]

I'm still using the same O ring that came on the gun in 1978 or so.

[@bobburnitt1411]

I have a Rem 1100 tact 4. How long does the O ring last if it is not fired often?? I am curious about that. My Cutting Torches and things like that, if the O rings are exposed to AIR they will go BAD whether they are used or not. I don't shoot this weapon often because of the high cost. So, it stays in the safe most of the time. It is my belief they will go bad whether you shoot it or not. I heard you say, "Every few years they should be changed out. Mine is about 6 years old, it is still PRISTINE but I would hate to pick it up and need it and it not GO. I live in an extremely high Crime area, but I have another shotgun I use and shoot more often, it is a PUMP. But the Rem 1100 I have holds 8 in the tube and 1 in the barrel it is a FINE firearm, i just wish I did not have to worry about a mickey mouse O ring when I pick it up to use. I figure the O ring will last quite awhile sitting in the safe, but maybe you have some experience with that. Thanks, BB

[@1957Shep]

+Bob Burnitt Inspect it once in a while. You can see if it is starting to get cracked or damaged. If you keep it lubed so that it doesn`t dry out it will last much longer. If it isn`t allowed to dry out, and not used much, it might last 20 years or more. I try to change mine out every 5 years or so. But mine gets shot a fair amount. For a self defense gun, I would change it every few years even if it doesn`t need to be. Better safe than sorry. I would hate to find out that it split when I needed it. If it does fail, you can still fire the gun. It just will not eject the spent hull. So you have to pull the bolt back to eject the spent hull and chamber a new round. The gas seal is cheap, so there isn`t much expense involed.

[@bobburnitt1411]

1957Shep Hey THANKS!!! Some O rings on some other things might not like certain kinds of OIL, but I would think Rem Oil would be FINE to lube it with. If the tube was sticky or dry, just the action of the gun being fired would knock the O ring out in one firing would be my guess. Thanks Again, BB

[@1957Shep]

+Bob Burnitt Any light gun oil, like Rem Oil ought to be fine. The barrel lug will keep the O-ring from moving forward out of the groove. The O-ring is just a seal that keeps the gas from the barrel ports from escaping forward instead of pushing the piston to the rear to help work the action. Keep in mind that if the outside of the magazine tube where the piston moves back and forth gets excessively dirty or rusty, it can cause similar problems.

[@bobburnitt1411]

1957Shep Ok THANKS, since Remington Makes the Firearm, I kind of figured REM Oil would be good, but you know, I am not an expert, so I like to ask people that have more experience. Thanks Again for the reply, BB

[@jmacx431]

I have the same gun, if I tilt my gun and the piston seal shifts back and forth when I tip the gun, is that normal?

[@themrttttoo490]

Yep

[@1pieman]

Clean 1100 I have never replaced the o ring I always use white grease on all o rings would it collect to much junk

[@1957Shep]

Good idea.
