The TIGRE USA INC 36-695 is a 4-inch male pipe thread (MPT) plug used to seal and cap open pipe ends in drain, waste, and vent piping systems. This fitting threads directly onto female-threaded fittings or pipe openings, creating a secure, pressure-tight closure. At 4 inches, it is sized for larger-diameter pipe runs commonly found in commercial and residential drain lines. Licensed plumbers and pipefitters install this plug during pressure testing, system commissioning, or when permanently capping unused branch connections.
The 36-695 plug is suited for use in drain, waste, and vent (DWV) applications as well as general pipe termination work. It is commonly installed in both new construction and retrofit plumbing projects where a 4-inch male-threaded termination is required. The plug ships in a package of 10 units, making it practical for jobsite use where multiple caps are needed across a single system or across several rough-in locations.
Designed as an OEM-style replacement and standard fitting for 4-inch female pipe thread connections in residential and commercial plumbing piping systems.
Installation is performed by a licensed plumber or qualified pipefitter. Shut off water supply and depressurize the system before threading the plug into place. Apply appropriate thread sealant or PTFE tape to the male threads per IPC and local code requirements. Do not overtighten; hand-tighten and finish with a strap wrench to avoid cracking the fitting or damaging mating threads.
