as soon as I get my 3d printer working again I'm printing an arl clip i just don't want to deal with it. i have a pack of #14 o rings. I believe that's the size that I need.
A good way to start is by listening for the leak. Often a leak caused by the piston head will be heard more from the entrance of the cylinder where the piston head goes in. A leak from the cylinder head will often be heard from the cylinder head itself. Another method of testing is to try to isolate the variables. Teflon taping the cylinder head fixes most leaking that would be caused by the cylinder head unless the cylinder head is cracked and air can escape from somewhere other than the o ring. If you teflon tape the cylinder head and the leaking persists, there is a great chance that the leak is coming from your piston head. It should also go without saying that it is important to use the appropriate lubricant when testing this, and not to run it dry or dirty. The air nozzle should also be disregarded for the sake of diagnosing this leak. I hope this helps!
@@anttechairsoft Thank you! Also, I sanded off some of the Action Army’s piston’s white guide rings (not the blue piston itself), could that be causing air leaks or is the o-ring the only thing that needs to be good to prevent piston leaks?
19.05 ID x 23.8125 OD x 2.38125 Wall This is the exact conversion from Inches to Millimeters of the O-Rings I’m using. I suggest rounding these numbers up and down, ordering different sized O- Rings based on your results, and test which tolerance best suits you. Good luck!
Can an Oring be too big? Like I put an oring on and try to put the piston into the cylinder some part of that Oring is stuck sticking out from me trying to squeeze it in, I have to use my fingers to poke the protruding Oring into cylinder, is it too big for the cylinder?
It could be too big. Aside from the obvious size difference in Bore-Up kits, you will find some significant size differences across different brands of standard piston head O-Rings. It should also be noted that an appropriate sized O-Ring could pop out as you have described. Keep in mind that the piston head never leaves the cylinder during the cycling of the gearbox, so as long as that piston head O-Ring offers perfect compression going forward and allows air to escape when being pulled back, it is okay! Also note that you may still lose compression with a brand new O-ring if the piston head itself is sub par such as a stock G&G piston head. I really can’t recommend Lonex POM and Prommy POM piston heads enough for air seal as they have never let me down!
@@anttechairsoft Hm I guess it is either the piston head or the oring then, had been getting inconsistent fps but blowing air down the barrel shows perfect airseal, thanks for the heads up
@@EC-hf8ui inconsistencies can also be caused by your nozzle not making it all the way forward in time. Try removing a coil or two from your Tappet spring, and also check the Tappet plate fitment in your gearbox shell to ensure that it is smooth and can drop freely with little to no friction. Close the shell (with all screws) with nothing but the Tappet plate in there and rotate the shells back and forth. Gravity should be enough to slide the Tappet plate forward and backward.
@@anttechairsoft Thanks for the tip, turns out it is the piston head and not the Oring, the fps is higher with the new Piston even if I use a smaller oring
great information brother! This video explains comprression very well. thanks for the up close video! lets grow this airsoft community.. hitting that sub button now! feel free to share the love with a follow back cheers looking foward to your next video !
When I made this video, I was studying music in college. I play guitar and I was studying/ performing jazz and classical guitar. The long nails on my strumming hand helped me get a good tone with my finger picking technique! Very common grooming practice for classical guitarists lol. The long nail doubled as a pretty useful tool when teching too if I’m being completely honest 😂

How do I figure out where an air leak is in a cylinder? And how can I differentiate from a leaking cylinder head or the piston?

@@skiddynebula2706 The whole relationship between your piston head, o ring, cylinder, cylinder head has to be good.
What size of o-ring should I get (in millimeters)?

@@anttechairsoft Thanks for telling me that I haven't thought of that at all! Thanks a lot

What size o-ring should i use? Mine are bad and cant get em online, so i need to go to a hardware shop to get some
3/4” ID x 15/16” OD x 3/32” Wall 🙂
Whats the size for the cylinder head o-rings i cant seem to get that info i know its a size 14 but its thinner than the piston head .. Thanks
nicolas7183 I’ve measured OD .90”, ID .85” and Wall thickness as .05”
bro my piston doesn't even stop rip
Use Teflon tape underneath ur o rings you will get a massive increase

Great tutorial, but your thumb nail creeps me out lol
Long nails were for playing classical guitar back when I was still studying music! They also made for useful tools when teching lol
Why the long nails?😂
I was thinking that the whole time. Wtf

Use Teflon tape underneath your o ring thank me later 💪
