Mars mars-93803 Leak Lock Joint Sealer 1.33 Oz

Product Description

The MARS mars-93803 is a pourable paste joint sealer supplied in a 1.33 oz tube. Formulated as a thread and joint sealant, it is applied to pipe threads and fittings to prevent gas and fluid leaks at mechanical connections. The blue/gray paste consistency allows controlled application directly from the tube, filling thread voids and curing to form a durable, pressure-resistant seal. It is alcohol-based, making it compatible with a range of pipe materials and thread sealant applications. Licensed plumbers, HVAC technicians, and gas fitters keep this type of sealant on hand for routine service and new installation work.

This joint sealer is suited for use on threaded pipe connections in residential and light commercial plumbing, HVAC, and gas piping systems. The small 1.33 oz tube format is practical for field service technicians who need a portable, single-job quantity of thread sealant. It is applied during assembly of threaded fittings before the joint is made up, ensuring a leak-free connection on first pressure test.

Installation Notes

Applied by licensed plumbers or HVAC technicians to male pipe threads before joint assembly. Shut off all gas or fluid supply and relieve system pressure before disassembling any existing connections. Apply an even coating of paste to the threads, assemble the fitting hand-tight, then torque to the fitting manufacturer's recommendation. Allow adequate cure time before restoring system pressure and performing a leak test per applicable code requirements.
