teflon tape

Terry St.James_2

I do not know about the code in the USA but here in Canada no teflon is allowed on any fuel from oils to gas. Although there is a teflon on the market(pink in color) that is allowed on natural gas here. Still I get nervous using it myself,always think that a piece could block something,like on orifice. Even on air lines teflon can cause trouble if not put on the right way(two threads min.from start of threads).
I WOULD LIKE TO HEAR WHAT PIPE SEALANTS ARE USED ELSEWHERE. Here in Quebec Canada we can it "paint"
but when I lived in the west it was called "dope"(a few helpers were called that also but that's another story)

Teflon tape

In my experiance teflon tape or teflon compounds should not be used on anything other than 1/4"or 3/8 chrome plated brass, the food and drug industry where totally inert compounds are needed.

Teflon is a fantastic lubricant and if used where vibration or pipe movent occurs or on petroleum based products or gas piping, leaks will occur in the future.

There is a pipe compound for everything, most are all purpose but some are for specific use and may cost a bit more. If the right compunds are used less or no come backs will prevail. Rework cost a lot of money and it eats into your pocket.
