Brennan 16030 Steel Hex Plug 1/2 Inch Mnpt Fitting

Product Description

The BRENNAN 16030 is a steel hex plug designed to close off open pipe ends in industrial and commercial piping systems. It features a 1/2-inch male NPT (MNPT) threaded connection that installs directly into a female-threaded port or fitting. The hex head allows for standard wrench engagement, making installation and removal straightforward without special tools. This plug is used to block unused ports, cap off test points, or seal dead-end connections in pressurized pipe assemblies. Fabricated from steel, it is suited for use in demanding environments where durability and thread integrity are required.

This hex plug is a standard pipe fitting used across plumbing, HVAC, hydraulic, and industrial piping applications. It is typically installed by licensed plumbers, pipefitters, and HVAC technicians when capping off unused tee branches, manifold ports, or instrument connections. The 1/2-inch MNPT size is one of the most common thread sizes encountered in residential and light commercial piping systems, as well as in industrial equipment.

Key Features

• 1/2-inch male NPT (MNPT) thread for direct installation into female-threaded ports
• Hex head design accepts standard wrenches for secure tightening
• Steel construction for durability in industrial and commercial service
• Seals open pipe ends and unused ports in pressurized systems
• Standard UNSPSC classification 40175305 for pipe fittings procurement

Compatibility

Designed as a standard MNPT hex plug for use with any female NPT-threaded pipe, fitting, or port in 1/2-inch pipe size applications.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Depressurize and isolate the system before installing or removing any pipe plug. Apply thread sealant tape or compound to the male threads prior to installation in accordance with applicable plumbing codes such as the IPC or IFGC. Tighten using a wrench to achieve full thread engagement without over-torquing the fitting.
