Pipe Thread Sealant for Metal Fittings

Loctite 135486 is an anaerobic pipe thread sealant designed for metal hydraulic systems. The purple liquid cures in the absence of air to create a reliable seal on threaded connections. It suits maintenance technicians and engineers who need a dependable sealing solution for fluid power applications.

Anaerobic Cure with Brush Application

The product cures anaerobically once confined between metal threads, forming a solid thermoset plastic that resists vibration and shock. Supplied in a 1.7 fl oz bottle, it is applied directly with the integrated brush for controlled coverage on each fitting. Clean-up uses Loctite solvent before the material fully sets.
