High Performance Thread Sealant (56521) by Permatex®, 50 ml Tube. Superior to Teflon tape and pipe dopes, this OEM specified product provides a leak-proof seal under the harshest conditions, protects mated threaded areas from rust and corrosion, and minimizes galling. It is exclusively formulated to withstand up to 10,000 PSI for fast, responsive curing on metal, tapered pipe thread fittings. Contains PTFE (polytetrafluoroethylene, also known as teflon), a material with good antifriction properties and high resistance to chemicals and aggressive environments. Do not use on plastic piping.
