[edit]HAHAHAHA! SHIT ! thanks for any info posted but right now THE END CAP FROM THE AIR CHAMBER EXPLODED SO! after 24 hours my first air cannon has died.

hi all, i have a question. my air cannon is working fine until i pump the air chamber to about 120 psi then it would start leaking. any ideas or ways to fix this problem? :(

thanks :wink:

fill a spray bottle with soapy water. spray. mark where bubbles are coming from. seal with epoxy. i used jb weld when mine had a leak.

open up your cannon, put come plumbing glue over the leak. pressurize it to 20 psi for about 2 mins. shoot, and let dry for 24 hrs.

to find out where the leak is: fill a bucket with water, pump up your rifle, and place it in the water. you will see a stream of bubbles comming out of somewhere. bingo you have found your leak

What country do you live in?
It helps to know so correct answers can be given. Fill out your profile!

That s pretty thin walled PVC for air pressue applications. Look more like DWV fittings.
What size is the Tee?
