Scotch-Weld PS77 (formerly Rite-Lok) is a single component, medium strength, anaerobic pipe sealant.

PS77 is a thixotropic pipe sealant that cures quickly on steel pipes. Scotch-Weld PS77 cures when confined in the absence of air between close-fitting metal surfaces.

Key Features:

Scotch-Weld PS77 is formulated to lock and seal medium to coarse straight and tapered pipe threads on pipes of diameter from 15mm to 80mm. PS77 prevents vibration loosening and leakage through the pipe threads. PS77 is formulated to give medium strength break torque, but lower prevail torque on assembled joints, thus enabling easier disassembly and servicing. Pipe joints made with PS77 should be fully torqued up within a maximum of 15 minutes from initial assembly. PS77 will give a rapid low pressure seal (after 20 mins).
