The JOMAR 400-101 is a 2 oz tube of Green Stuff thread sealant designed for use on pipe thread connections. Thread sealants are applied to male pipe threads before assembly to fill gaps, prevent leaks, and resist loosening under vibration and pressure. The 400-101 uses a green-colored paste formula that is easy to apply by hand or brush and seats between mating threads during tightening. Plumbers, pipefitters, and HVAC technicians routinely use thread sealants on threaded pipe joints in gas, water, and mechanical systems.
The JOMAR 400-101 is suited for residential and light commercial applications where threaded pipe joints require a reliable, non-hardening seal. It is commonly used on low-pressure piping assemblies including water supply lines, gas distribution piping, and HVAC condensate and refrigerant line fittings. The 2 oz tube size is practical for field service work and individual repair jobs where a full bulk container is not needed.
Designed as an OEM-style thread sealant for use on standard threaded pipe connections in plumbing, HVAC, and mechanical piping systems.
Thread sealants are installed by licensed plumbers, pipefitters, and HVAC technicians in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the pipe system before disassembling or assembling any threaded joint. Apply sealant to clean, dry male threads only, leaving the first thread bare to prevent contamination of the pipe interior. Allow adequate cure time before pressurizing the system per the product instructions.
