Product description


B573 is a single component, thixotropic anaerobic compound. B573 is designed for low strength sealing of large areas and machined surfaces. B573 allows for easy disassembly and is resistant to most industrial fluids.


B572 has good chemical/solvent resistance to ethanol, motor oil, unleaded petrol and brake fluid. B572 is unusual in that it does not fully cure until some 60 hours after application, allowing for re-alignment of elbows and joints. Replaces tapes and dopes, stops gas and fluid leaks on most metals and assists in lubricating during assembly.
