The JOMAR 400-004 is a Teflon-based thread sealant formulated for use on threaded pipe connections. It comes in a 1-pint container and is applied to male pipe threads before assembly to create a leak-resistant seal. This type of compound is a standard consumable in plumbing, HVAC, and mechanical contracting work. It is compatible with a wide range of threaded fittings and is a common fixture on service vehicles and in supply rooms where threaded pipe work is performed regularly.
Thread sealant compounds like the JOMAR 400-004 are used across residential and light commercial plumbing and HVAC installations wherever threaded pipe joints are made. Typical applications include water supply lines, gas lines where approved, and hydronic heating systems. The 1-pint container size is practical for frequent field use by service technicians and installers who work with threaded connections on a daily basis.
Designed for use on threaded pipe connections typical in plumbing, HVAC, and mechanical piping systems. Verify suitability for specific media such as gas or potable water before application.
Thread sealant is typically applied by licensed plumbers and HVAC technicians in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the line before disassembling any existing threaded joint. Apply the compound evenly to male threads only, then assemble and tighten to hand-tight before using a wrench. Do not over-apply, as excess compound can enter the pipe interior.
