Frequently Asked Questions

Q. "Is the TU-555 thread sealing compound compatible with PTFE pipe tape?"
A.Yes. Sometimes adding a good quality thread compound on top of the PTFE thread sealing tape helps seal joints even better. This is often done to natural and propane gas steel pipe and fittings to help make a better thread seal.
