Brennan 16005 Steel Hex Plug 3/8 Inch Mnpt

Product Description

The BRENNAN 16005 is a steel hex plug used to seal threaded pipe openings in industrial and commercial piping systems. Machined with male NPT threads on both ends, this hex plug is sized at 3/8 inch male thread and threads directly into female-threaded fittings, manifolds, or pipe tees to cap unused ports. The hex head accepts a standard wrench for installation and removal. Steel construction provides durability in high-pressure and high-temperature pipe environments. This plug is a standard component in fluid, air, and gas distribution systems where ports need to be sealed or temporarily blocked.

This hex plug is used in industrial pipe assemblies where unused MNPT ports must be sealed. Typical applications include hydraulic lines, compressed air distribution, water lines, and general industrial plumbing. Plumbers, pipefitters, and maintenance technicians install these plugs during system commissioning, pressure testing, or port blocking in manifolds and distribution blocks. The 3/8 inch MNPT size fits a wide range of standard pipe fittings used across commercial and industrial installations.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and IFGC codes. Depressurize and isolate the pipe section before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to male threads before seating. Do not overtighten, as this can damage the female-threaded receiving fitting.
