Installing the ferrel connection on the gas furnace

[@johnbraden727]

Thank you for posting this video! Super helpful! I was at a loss about how to repair a broken pilot feed on our old furnace. Purchased the connectors and tube in your video and the repair took about 10 minutes. Your expertise and sharing is greatly appreciated!

[@jimmiellis]

GFM tutorials are excellent, in depth, and easy to understand. Watching all his vids closely, especially with mobile home furnaces and gas valves, saved me $900! All the young, so called repairmen, are nothing but replacemen. My Coleman is 39. I had no less than 3 or 4 companies the past two years send techs who didn't know how to light my old pilot or give a definite diagnosis if the gas valve was bad. Replace the entire system they all said to the tune of 11 and 12gs! Following GFM vids I was able to successfully replace my gas valve, pilot tubing and thermocouple. With the money I saved buying the gas valve online rather than a local supplier, i bought tools i needed including a gas leak detector. Also checked w bubbles to be safe. Its been 2 weeks and we should be set for the colder months ahead!

Glad you got it going. GFM

GFM, you have the best videos. Thanks so much. This video has helped so many people over the years. It certainly helped me.

[@erichorton1440]

The video I clicked on before this wants to charge people money for this information. Inlove when people give free info.

[@jimmiellis]

Thanks for explaining the ferules and how they work. I've watched many other similar vids and nobody explains how they break off and seal. Very important safety info to know. i's the simple things overlooked that make a difference. thank you!

[@wjefflusk]

That is exactly what I needed to see. Thank you!

[@stevesurowiec6229]

Just replaced the pilot burner/igniter and gas delivery tube on the heater side of my 26 year old HVAC unit. Thanks to your video I was able to make the gas connections with no leakage problems. It fired right up and we have heat again. Appreciate you sharing your knowledge and techniques. You rock grayfurnaceman!!

[@ghosttownhunts]

Even 8 years later I’m watching and learning thank you sir!

[@Sven95lwb]

Thanks for the tip of oil on the threads. I replaced a pilot tube on a gas fireplace and had a hard time sealing it. Oil worked great!

[@grayfurnaceman]

Welcome GFM

[@sbitschy]

grayfurnaceman I had the same - leaking along tubing after removing and putting it back in. Oil worked great but is it a long term solution like pipedope. I picture pipedope being a more permanent seal? Any thoughts?

[@grayfurnaceman]

It has been long term for me. Because it reduces friction, it concentrates more torque on the seating surface. GFM

[@sbitschy]

grayfurnaceman thx

[@garysmith10449]

Best way I learned is to screw the ferrule into the gas valve by finger tight and then put the tube into the feral with a mark on on the tube for the depth and then tighten it up with a wrench to snap the federal off there's no way you can cross threaded doing it that way

[@ManuelHernandez-tp1gh]

Very informative, thanks for explanation how this works. Wasn't sure if I can cut the old one out. Blessings to you.

[@grayfurnaceman]

Welcome GFM

[@rustyw1229]

Thanks! Was having a terrible time understanding how the fitting was working based on instructions I was reading for a set of gas logs and a Dexen 6003 millivolt pilot valve. In this case the tube didn't go through the end of the fitting and was just flush with the end but it still worked and I heard it break off.

[@MattWeis]

Great video! Super informative, thank you!

[@BigZeus]

Thanks for this, got a new water heater and its leaking here at the threads straight from the factory. They sent me a new gas valve overnight, was looking at tips when installing it. Think i've got it all figured out.

Can I use vegetable oil or does it have to be a specific type of oil?

[@grayfurnaceman]

Any lubricant should do. GFM

[@1indocreative]

where the thermostat place sir?

[@allsold]

oil ? can I use Silicone Lubricant from spray or apply on it?

[@grayfurnaceman]

Sure, anything that reduces friction so more force can be applied to the sealing surfaces rather than the threads. GFM

[@Straycurrent]

Tightening brass into aluminum is scary. Do you expect to feel the ferrel to break 100% of the time or sometimes can it seal without breaking off the fitting? Excellent video.

[@grayfurnaceman]

Straycurrent They have always broken for me. Thanks for the support. GFM

[@HowardGoldman]

Can they be reused, or must a new breakaway ferrel be used if the tubing is being reattached? If new, then I suppose that means trimming an inch or so off the end of the tubing.

[@grayfurnaceman]

If you are simply removing the tubing assembly for component replacement, they can be reused if there are no leaks. If it must be replaced, you must either cut the end off and, if the tubing is straight, reuse it or replace the entire pilot tube and fittings. GFM

[@pliktra797]

Hi! Is the breakway piece supposed to actually ‘snap’ off? I have a similar pilot valve that is using 3/16” aluminum tubing and the respective 3/16” brass breakway ferrule. I tighten until I begin to strip the hexagonal shape and then I stop in order not to strip it anymore. However, the aluminum tubing is still moving freely in and out of the breakway ferrule piece. What am I doing wrong? Thanks

[@paulhealey2984]

Did you get it sorted?

[@pliktra797]

@@paulhealey2984 yes i did, thanks for replying, even if it took 4 years!

[@haywardkong1213]

Question can you use any kind if oil for the breakaway ferrel? air tools oil?

[@grayfurnaceman]

As long as its slippery, its ok. GFM

[@kimberlyrenoagapion4754]

Quick question! When replacing the thermocouple unit on my gas fireplace I overtightened the nut on the pilot tube and the pilot tube broke off. I thought it was 1/4 but that’s too big. I have everything to connect the 1/4 in aluminum pilot tube-is there a way to use an adapter to size down to 1/8? Or is it best if I try to find a 1/8 pilot tube and fittings?

[@grayfurnaceman]

I would be looking for the 1/8" tube. GFM

[@wenzdayjane]

If the threads start crossing, do you think it's possible to clean them up with a die/tap? are they NPT threads?

[@grayfurnaceman]

They are not NPT. If you have a set of taps and dies, you can look for the right TPH and maybe it will work but I would change the fitting. GFM

[@Steve923]

Wonder why no tape or thread sealant used on the pilot gas tube?

[@grayfurnaceman]

You can use oil on the threads to reduce friction on the threads, but the threads do not seal. You can also apply a very small amount of thread sealer to the ferrel surface that may help. GFM

[@1drhnsd1]

Where can I get the ferrule fitting you are showing?

[@grayfurnaceman]

About the only place I know of is a gas parts house. Some propane suppliers may also have it. GFM

[@anthonyhitchings1051]

thanks ever so much

[@garysmith10449]

Could you do another video showing it that way. How to do it

[@gunit6815]

So when it breaks off, you leave the broken part in the valve, or do you take it out remove the broken piece and reinstall?

[@grayfurnaceman]

There is no broken part. The ferrel is the part that shears off. GFM

[@creepingdeth141]

How much should be sticking out of the ferrule?

[@grayfurnaceman]

Push the tube into the fitting until it bottoms out. GFM

[@geojor]

interesting stuff, thank you...

[@ilovenythismuchilovenewyor5801]

what kind of oil are you using is like motor oil or like 2 stroke oil ??

[@grayfurnaceman]

I use zoom spout oil. It is available at hardware stores but most anything will work. GFM

Very helpful

[@randyu8688]

I was tightening the ferrule and after it was tight the line came off and I untightened it and the part that breaks off fell off and now I can't put it back on the line

[@grayfurnaceman]

Cut off the end of the tubing and if the tubing is long enough, start over with another ferrel assembly. GFM

[@geojor]

thank you...

[@caddyinhere12]

Good video

[@RogerPack]

So once it breaks off is it "tight enough"? Can you just go straight to pipe dope? Also might be helpful to rename title to "breakaway ferrel for pilot" so people can find it easier using google :)

[@grayfurnaceman]

I generally ignore when it breaks off as I have been doing this for so long that I just feel the torque. For someone without that feel, I guess it would just have to be "snug" then check for leaks. Yes, you can use pipe dope (sparingly) to start with. I will see what I can do about the search. GFM

[@RogerPack]

@@grayfurnaceman Thanks, super useful explanation!

[@samuelhenton3258]

Hank Hill?

[@charlesjackel2247]

What do you mean exactly by "breaking off the fitting" ? Does the section of tubing beyond the ferrel break off? Can you disconnect the fitting from the valve and re-install it ?

[@rgs1628]

No the aluminum tube does not break off. The brass ferrule fitting (aka "breakaway" fitting) breaks into 2 pieces. When the fitting is tightened, the ferrule (flared part) breaks away at the narrow point where it is connected the the threaded part of the fitting, and then the ferrule portion ends up tightly griping and sealing the tubing. Yes, you can disconnect the fitting/tube from the gas valve and then reinstall it as many times as you like, as long as it still seals. You would have to put a new "breakway" ferrule fitting on the aluminum tube if the surface on the old ferrule was damaged and you could not get it to seal.

To check for pilot leaks u use my sense if smell first, then double ckeck it wih a lighter. I know it is a bad habit but is faster. Shame on me
