PERMATEX Seal+Lock Thread Compound – 35 ml tube, carded

Seal + Lock Thread Compound is a one-of-a-kind product that combines the power of a thread sealant and a thread locker into one. With this hybrid anaerobic formulation, sealed connections will not loosen and locked fittings will not leak. Formula seals to 1,000 psi, locks to 120 lbs. sq. in. and is temperature resistant between -60°F to 300°F.
