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

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

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?

Well I answered my questions via this link;
