Sealants

Protect lines, assemblies, and systems from leaks and loose fittings with standard to heavy duty strength sealants

Sealants come in a variety of adhesive bases such as silicone-based, multi-purpose anaerobic gels, Loctite sealants, caulks, pipe tapes, cold weld compounds, and thread sealants. Sealants are appropriate for applications that range from applying adhesives to ceramic items, fiberglass products, and woodwork, to sealing gaskets and flanges. Choose the right sealant for the specific application you have on hand.
