Loctite 735892 5045 Flange Sealant

Product Description

The LOCTITE 735892 is a flange sealant designed to seal and secure metal flange joints against leaks. Known under the 5045 product line, this compound fills gaps and surface imperfections between mating flanges, providing a reliable seal that resists fluids, gases, and pressure once cured. It is well suited for use in plumbing, HVAC, and general mechanical assemblies where rigid flange connections require a dependable, non-drying seal. Licensed tradespeople and maintenance technicians working on pipe flanges and bolted assemblies are the primary installers of this product.

This flange sealant is applied to metal-to-metal flange surfaces in both residential and light commercial settings. Typical applications include sealing pipe flanges, pump housings, compressor flanges, and similar bolted joint assemblies where a gasketing compound or thread sealant is required to maintain system integrity under operating pressures and temperatures. It is appropriate for use where a formed-in-place gasket is needed on closely mating surfaces.
