Loctite 135491 Pipe Sealant is a white thread locking and sealing paste with methacrylate ester base, designed for securely sealing metal tapered threads and fittings in industrial applications. It cures anaerobically when air is excluded between close-fitting metal surfaces, providing protection against loosening and leaks caused by shock and vibration.

This single-component sealant offers excellent lubricating properties that prevent galling on stainless steel, aluminium, and other metal pipes or fittings. Its high viscosity range of 280,000 to 800,000 mPa·s supports reliable joint integrity and chemical resistance.

The sealant operates effectively within a temperature range from -55°C up to a maximum of 200°C, making it suitable for harsh industrial environments.

Its 1.7Nm breakaway torque rating ensures a strong but releasable sealant bond, ideal for pipe fittings up to 2 inches. The product does not creep, shrink, or block systems, and cures rapidly to provide immediate sealing.

Applications include automotive industry, chemical processing, petroleum refining, gas transport, marine applications, power systems, and waste treatment facilities. Easy application enhances productivity and safety during installation.
