Best stuff to seal CO2 threads?

[Anonymous]

I have been using teflon tape to seal threads on regulator and bubble valve etc- but I don't think thats exactly correct...?

As long as the thread does not leak, there is no need to check into specialty tape.

If you want, you can get those yellow teflon tape for gas pipe (natural gas), but I doubt that it will make much difference... maybe 5 more sec. out of that 10 lb. cylinder???

Yeah, most co2 fittings are flared to seal when you tighten them down. If they aren't sealing, you might have a mis-matched set, or a ding in either the nipple or recepticle. Take a close look, you may have to replace one or the other.

If you're using teflon tape, use the stuff that's for gas lines. (just like loule said.)

Also, don't get carried away with the tape, especially if the fittings are plastic. 2-3 turns is plenty. Too much tape can be counter productive.

(For this hobby, most fittings are NPT instead of flared)

actually, i went to the co2 place the other day to refill my tank

they said NO TAPE

and gave me a black disc to use.

its almost like cork/cardboard

you shouldent use tape to make the seal between the regulator and the tank, when they refill my tank they always give me a new washer to install between the regulator and the tank, make sure to get a nice tite seal.

I agree - sorry if my comment caused some confusion. Just to clarify - normally you would use a thread sealant (liquid, tape, etc.) on a pipe-thread fitting. A thread sealant shouldn't be necessary for a flared-thread fitting (as mentioned above).
