Survey question... How often does everyone replace the nylon washer between the tank and the regulator?
Also if you use MFL's how often there?
Never. Should last long time.
I replace the nylon washer between cylinder and reg every time I refil the cylinder.
I've never replaced the ones in the MFLs because I haven't had them apart.
I think I had one tank washer crack a couple years ago, other than that, I rarely replace them.
MFL's only get replaced if I lose one or if I accidentally over tighten they might get deformed enough to leak.
This is my concern with the washer. Fireline gives me a new one everytime I get a refil so I use it.
I periodically spray star san on my gas fittings to make sure they aren't leaking. I only change the washer if it looks bad or I detect a leak.
Keg lube again works great... Very lightly, and I do use a wrench to be sure the connection is just passed snug. I really don't over tighten and destroy the flat, rubber/vinyl washer. Sneezles61
Never. Don't over tighten the regulator it's not much pressure
Never. One of my regs has a "built in" washer so let's hope it lasts a long time.
