I wanted to ask everyone about any experience or tips they have for me installing anti-siphon tubes for the first time. Obviously, empty the tank to start. One major question I have is regarding loctite. I have read threads saying there was someone who was killed because loctite had clogged the safety hole on the valve and turned the tank into a bottle rocket. However, most guides I have read for installing anti siphon tubes state to use loctite. I am not sure if it should be used on the anti-siphon tube connection to the valve and/or the valve to the tank. Also, I dont have a vice, so if anyone has any uther tips on removing the valve that would help. I guess in summary, if you have ever installed anti-siphon tubes, could you post the procedure you follow/ed? Thanks!

Just let a pro-shop do it. From what I understand, both deaths related to the sport of Paintball have been due to this same reason.

No proshops nearby me, plus I am very capable. I have done all sorts of hardware projects, as well as fine electronics soldering 32 AWG wire to ASIC legs side by side. I'm sure this means nothing to you, but consider it heart surgery to electronics. I know all about being careful and have plenty of experience and tools. I have just never done this so before going and doing it "my way," I wanted to hear what everyone else can share.

Thanks!

teflon tape, one wrap, dont overdo it, make sure it is at the top of the valve, not the bottom.

So use only Teflon tape on the A/S tube threads? And no loctite or anything on the valve threads to the tank? Just want to make sure I got it right. Thanks!

Use permanent red locktite or green.

Locktite does not clog anything if you apply it correctly. You only use a small drop on the threads. The only way it will clog anything is if you glob it on the threads.

So if I am getting this right, I don't need to put anything on between the anti siphon tube and the valve, but I need loctite for the valve-to-tank threads? I am reading a lot that says to never use loctite on the valve threads. Is it ok, or recommended to do this without loctite? Just want to make sure I'm clear. Thanks!

Correct tube to valve doesn't need anything special.


People advise against loctite for those who don't know how to use it (glob it on and such).

If you use loctite apply it to the trailing threads ( the ones closest to the valve-bottle o-ring). This prevents the loctite from clogging any safety feature on the valve stem and will keep the valve in place. I'd recommend red loctite as green is a pain in the ass even when heat is applied.

For CO2 tanks, especially use loctite. I'd go with blue or red (red if you want more permanent). Also be sure to mark the side of the valve that has the siphon tube pointing up once you get it installed. You'll probably need a vice though to get it on/off, or a pipe wrench and a strap wrench.
