Permatex High-Temperature Thread Sealant

4.47 out of 5 stars 19 Customer Reviews

Permatex high-temperature thread sealant is an OEM-specified product designed to lock and seal threaded fittings on a range of applications. It prevents leakage from vibration, temperature cycling, and extreme pressures—and it won't shred or tear like PTFE tape. This high-temperature thread sealant is exclusively formulated to withstand up to 10,000 psi for fast, responsive curing on metal, tapered pipe thread fittings. The PTFE offers good antifriction properties and high resistance to chemicals and harsh environments. The sealant is not intended for use on plastic piping.
