How to Replace a Leaking O-ring in the P15 Air Cylinder

[@AirWeapons-Thesis]

The same happened to me yesterday in my Diana Skyhawk 177, I fixed it after getting idea from your video. Actually your video was definitely a Tutorial class for me, your explanation is exactly as a teacher, lots of love and good wishes for your good health and happiness. Thank you sir 🙏

[@aaroncantrell8819]

Thank you so much. You are so lucky to have obtained a Skyhawk before they were discontinued. Best of luck.

[@curtisbarton2908]

Don't change anything your doing bud.Your honesty and help are really good for the sport!

[@aaroncantrell8819]

Thanks and best of luck.

[@BigCT]

Thanks for this video. I very much enjoyed the pace and detail you shared. By following your detailed instructions (that are clearly the result of knowledge and experience gained over time), I was easily able to fix the O-Ring. It never even occurred to me that high pressure air heats and melts the ring which was clearly the case when I removed it. Lesson learned - do it slowly. Thanks again.

[@soccersox100]

I have only recently found your channel but just wanted to say thank you for not only this video but all of them . It's so refreshing to find someone who's keeping it real and not trying to push something on the guys watching , so again big thank you from here in the UK

[@aaroncantrell8819]

Thank you. I try to pass on everything I am learning while trying to offer affordable options to the viewers. Best wishes.

[@fjqtaxch9]

You can apply this very educational leak troubleshoot to other airguns. Then need the right o-rings. Please mention the o-ring sizes and durometers needed in the P15. Glad you're back again making videos! Love your night vision vids but you will need bug repellant lotion and treated clothing during the bug seasons.

[@aaroncantrell8819]

I have a ton of orings and I just match the old oring to the new one and replace it so I don't know the sizes. I am looking forward to doing some night vision video in the fall and I will be mindful of the biting bugs. Thanks.

Just got my P15 this week. Hand pump arrived today and a compressor arrives next week. Could not fill it for the life of me with the hand pump. Read both manuals forward and back, looked for info on the net, nothing. Found a Brit doing a takedown series on the P15 and started watching that just in case it proved useful, but with my girls in the room with me and his adult language, I clicked on your video since I knew it would be kid friendly. Didn't think it would be very useful to me, since my gun is new, but watched anyway. Out of nowhere you mentioned that if the gun is empty, you need to cock it in order for it to hold air. Bingo! Now my gun is full. The fact that they don't mention this in the very poor excuse for a manual that comes with it is incredible. Thank you.

[@aaroncantrell8819]

I think hand pumps are for superman and other action heroes only because most mortals just can't do it continually. I do not feel the need to learn how to breakdown the P15s because I have only had to change the fill port o-rings. I think that no one mentions the empty air tank filling problem because all guns have to be cocked when filling from empty. So as soon as one hears the are escaping the first thing they understand is that the hammer is pressing against the valve and letting the air out. But I do think that the owners manual should mention it. Thanks.

[@SLG1911]

@@aaroncantrell8819 I have now filled the gun 4 times with the hand pump, and am excited for the compressor to arrive this week. It is probably common knowledge among air gunners that the hammer presses on the valve when at rest, but being new to pcp's, I did not know that. The manual says that if it won't hold air, you should cock it and dryfire it. I did that and of course it took me right back to the same problem. Your video is the only place I have seen mention of the need to cock it. As a powder burner, I would never have guessed that the hammer presses the valve open when at rest, so that is good info for me to have. BTW, what pellets does your .25 P15 prefer? What size groups at what distance do you get with them? Thank again!

[@aaroncantrell8819]

​@@SLG1911 My P15 shots the JSB 25.39gr pellets at 800 fps. It is a only pellet I use in in it. I did a of video of the P15 at the range shooting from 10 to 100 yards but I can remember the group sizes. Look up the video and it will show the mildot holdover and the groups. Best of luck.

[@thomasapril9773]

Hey Aaron, I'm from South Africa, and just wanted to say thanks for this video, my p15 developed this problem and seeing you fix it gives me hope for fixing mine

[@thomasapril9773]

Hey Aaron, did the fix today, working perfectly, thank you for the helpfully and informative video

[@aaroncantrell8819]

I have three P15 and I have been pushing them for years and many have purchase them. So I promised them that I would pass on any problems I found with the gun. Fortunate this is the only issue I have had. You are my second viewer from South Africa so I have added you to my world map. I will be doing a shout out soon. Thanks for watching.

[@soderlind81]

Today this happend to me, and i remember this video when it came. Thanks Aaron for helping me fix this leak!

[@bluewater454]

Great to see you back! Wish there were more channels out there posting videos like this on servicing different air guns. Air leaks are a hazard of the hobby.

[@aaroncantrell8819]

If it is what you want just ask the youtubes you watch to do post more how to and repair videos when you comments to them. I think they will listen. Thanks for watching.

I always look forward to hearing from you Dave. I hope all is well.

[@heathhalfhill6867]

Glad I’m not the only person that leaves the fill probes in my guns. I use a soft rubber cap I found in the cooking section on Amazon-50 PCs for6$. I think they use them for olive oil metal pour nipples. Get a can of CO2/ compressed air to help clean my guns for those hard to reach places too. Q-tips sometimes leave cotton that’s hard to see and will make the new o-ring leak and the can of air gets that cotton out really good and gets the dust off gently but thoroughly. I still may get a P-15 even though I need another airgun like I need a hole in my head. Thanks for sharing your helpful tips and I’m glad your back and ok. Take care,God bless. S.W Pa

[@aaroncantrell8819]

I am aware that Q-tips can leave a bit of cotton so I use high pressure air to blow it out of places I can't see or reach. As for the probe I found that the cap from a car or tank innertube works perfectly. Thanks for watching and best of luck.

[@HermanBarardJr]

Man hang in there. Wishing you well from New Orleans. Please keep them coming, I look forward to seeing these videos weekly. Take care.

[@aaroncantrell8819]

I will try but it gets hard trying to find new content every week. I don't want to just post pesting and hunting video. Thanks for watching.

[@airnashville3883]

Many thanks Aaron! My 4 day old P15 had this happen after about 5 pressure fills. This seemed to solve the problem.

[@aaroncantrell8819]

It only takes the smallest piece of dust or dirt to make an o-ring leak. Glad to be of help. best of luck.

HI Aaron Great video as always i must say that out of all the folk that i watch i look forward to yours the Most ,i do enjoy them the information is very good. i was looking at the P15 as a rifle to purchase and from your video it will be easy to maintain i do like the odd hunting video but is is about the equipment that is being used would like to see some .25 cal and 30 cal when you get the time as i am getting into this in a big way. so great video cant wait for the next one UK

[@aaroncantrell8819]

I don't have many pesting opportunities for my .25 cal because they are over kill or just too dangerous for most of my application. However I do use them in target shooting and pellet testing. Thanks for watching.

Aaron, thanks for tour continued work and sharing on help with fixes for our airguns. On your P-15, did you add the cocking lever or did it always have the handle on it? Also, is there anything that can make the cocking smoother.

🔥🔥my guy👊🏾. I’m scared to try fix my own rifles. I would probably make it worst.😂

[@FirstStateAirgun]

Yip dats me too 😆

[@aaroncantrell8819]

It is like changing your own oil or plugging a flat tire or refilling your antifreeze or windshield washers. There is some maintenance that has to be done by the owner while saving the big jobs for the experts (transmission, break jobs, etc.). Thanks for watching.

[@bigmixx76]

Nice video same thing happened to my .25 Skyhawk/p15

[@aaroncantrell8819]

You are correct. Whether you have a Skyhawk or P15 you had better learn to replace the fill port o-ring. Thanks for watching.

[@shanebrownrigg8632]

Hi Aaron,great vids,don,t know which gun to buy p15 or the Kral puncher breaker,I’m in the uk,we are restricted on power,thanks

[@aaroncantrell8819]

I love both guns and the Puncher Breaker and they both about the same price. The Puncher Breaker was on my list to purchase because of its power wheel, accuracy and great looks. However it was heavy and a bit loud and unregulated. So I got the P15 because it was much lighter, more compact and regulated. However If I was in the uk I would consider the puncher breaker because with the power wheel it can be adjusted to 12 flbs by the owner. Best of luck.

[@paulandrews3785]

Great video buddy 😉 how ar you attaching your bipod to your stock please looks great

[@aaroncantrell8819]

I did it very cheaply. I cut off a piece of picatinny about three inches long. then I drilled a hole in it and put a screw through it into the wood on the stock. Had to do a little sanding to get it to fit but it works great. Best of luck.

[@paulandrews3785]

[@doubledge2947]

Aaron, does the pull length differ on the p15 vs FX wildcat, or impact? Some of the bullpup designs are too small and I don’t feel like building up the stock if it isn’t necessary. Also, what do you feel about the Zbroia vs the P15 closest competitor in terms of reliability?

[@aaroncantrell8819]

No the pull length does not differ because the P15 can be adjusted to any pull length you want. I am 6' 2" so I did have to build up the stock to accommodate my long reach. As for competition the Zbroia Kozak is a very well made gun but cost almost double the price of the P15 and it is much heavier if I recall correctly. Thanks for watching and best of luck.

[@doubledge2947]

aaron cantrell much appreciated

[@MarkDenovich]

Aaron, have you heard about an extended plenum for the P15 from Xtreme Airguns in South Africa? $73 delivered to the US about 3 days after the order. Really opens up the tuning window. I gained 50fps with the stock settings. Tuning for same power (32fpe) I had before the plenum it’s noticeably more quiet (and efficient). Interesting part for those who want to tinker. BTW: have you seen SPA’s new P35? It’s a P15 with a side lever. Looks like an FX Wildcat.

[@aaroncantrell8819]

That extended plenum sound like a nice upgrade. However, my P15s are perfect as is for what I want them to do which is just hunting and pesting. I looked up the Artemis P35 and could only find one video on it and it was in a language I did not understand. Glad to hear that you like the upgrades you have done to you gun. Thanks for watching and best of luck.

[@Xoxo-m-p3b]

Great video!!! Is that the only air leak problem in P15 or are there other parts that leaks air

[@aaroncantrell8819]

This is the only air leak I have had so far and it seems to occur about once a year. Thanks for watching.
