Propane Adaptor; Able to leave in tank?
 

I recently entered the world of GBB pistols with a KSC Glock 17 (metal rails and slide) and a KJW KP05 (full metal). Shot for the first time yesterday. A LOT of fun to be had with these...

My question;

Is it safe to leave a propane adaptor in the propane tank if you are not going to use the tank for refilling for a while (weeks, months)?

It seems more practical to me to leave the adaptor in the tank as it has a valve in it to prevent leakage. Also, I think that repeated insertion and removal of propane adaptor increases the chance of damaging gasket of the propane tank. I have a Madbull metal propane adaptor.

Any help from your experience is greatly appreciated. Thank you.

The adapter just screws on the top..it doesn't go "in" the tank. And yea, it's perfectly fine to leave it attached.

Don't Really know what you mean by "IN" the tank, but i leave mine screwed on all the time

Sorry for the confusion. "Attached to the tank in the usual fashion" is what I meant by "in" the tank. I should have stated more clearly the first time.

The information both of you have supplied is exactly what I wanted to know. Thank you for your help.

the only issue is that the adaptor can get pushed in and release your propane if you leave it on. the latest version has a cap to help prevent this.

The other issue is if it falls it can break where if its not on it will just hit the ground and nothing will happen.

if you look at it more closely, you'll notice the adapter valve and the propane tank valve don't contact each other unless you depress the tip to fill a mag. unlike CO2 adapters, when you unscrew the propane adapter, it is under zero pressure. Thus, completely safe to leave attached unless it happens to fall and break or something falls on it causing the tip to be pressed, then you may have a leak.

I have both the AI plastic w/cap and metal adapters. They stay installed 100% of the time. I use a syringe from a printer ink refill kit to put the silicone oil in. Saves the effort in screwing the adapter on and off.
