Supco SUPC-HS10004 Leak Lock Thread Sealant 4 Oz

Product Description

The SUPCO SUPC-HS10004 is a thread and joint sealant designed to prevent leaks across a wide range of pressures, from full vacuum up to 10,000 psi. Supplied in a 4 oz brush top jar for easy, controlled application, it bonds to metals, plastics, and other common materials without hardening or becoming brittle over time. The non-toxic, flexible formula remains pliable after cure, making it a practical choice for HVAC technicians, plumbers, and pipefitters working on pressurized systems where long-term seal integrity is required.

This sealant is suited for both residential and commercial applications wherever a reliable thread or joint seal is needed. It is commonly applied to pipe threads, fittings, and connections in gas, refrigerant, hydraulic, and water systems. The brush top jar format speeds up application on threaded connections and irregular joint surfaces without requiring additional tools. Any trade professional sealing pipe joints or fittings during installation or service work will find this format straightforward to use.
