One of my tanks that I use on my grill isn't getting a great seal and the problems looks to be on the threads where it leaves the tank and into the regulator. Obviously I don't want to use it this way and I want to use the tank that I just filled up. The question is, can I wrap the threads well with Teflon tape and be alright until I use this tank up? Basically, will the propane cause damage to the tape that will cause it to leak again soon?
