Air cannon leaks..

[nosnik]

[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

[edit] im using PVC

find the leak. seal the leak

[nosnik]

i know i have to find the leak and seal it. but how should i do it? (sealing the leak that is)

[geardog32]

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.

hahaha thanks but this info is now useless to me unless i can come up with a new air chamber.. the end cap exploded on me..

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.

[nosnik]

but it only leaks at about 100 psi.. i could not figure out where the leak was.

Epoxy.

'nuff said

if you could show us some pictures we will be in a better position to help you out

[chinnerz]

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

You've done something wrong if the end cap blew up. Post pictures so we can tell you what went wrong.

yeah so i uploaded what happened to the part of the air chamber where the end cap was suppose to be.. can anyone tell me if im using the wrong type of pvc? and where can i find a spring for a spring loaded ball valve.(having some trouble finding one)

says VUDL 50 on the pvc pieces..

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?
