3M™ Scotch-Weld™ Pipe Sealant Anaerobic Adhesives are one-component anaerobic sealants that cure and seal hydraulic and pneumatic pipes and fittings to withstand high temperatures and pressures. PS67 is a fast cure, low breakaway torque strength, high temperature past pipe sealant for metal connections in applications such as pressure vessels, air compressors, hydraulic, and pneumatic systems. It works on inactive surfaces (such as stainless steel) and provides and almost instant low pressure seal. A high pressure seal results when the bond is fully cured.Information provided by 3M |
