Brennan 16002 Steel Hex Plug 1/4 Inch Mnpt X Mnpt

Product Description

The BRENNAN 16002 is a steel hex plug designed to seal male-threaded pipe ports in industrial and mechanical piping systems. It features a male NPT thread on both ends at 1/4 inch, making it suitable for closing off open ports in manifolds, valve bodies, and pipe assemblies. The hex-shaped head accepts a standard wrench for secure installation and removal without requiring special tooling. Plumbers, pipefitters, and HVAC technicians commonly install this fitting during system fabrication, testing, or whenever an unused port needs to be blocked. The all-steel construction provides durability in demanding service environments.

This hex plug is used in residential and commercial piping applications where a threaded port must be capped or sealed. Typical scenarios include blocking unused outlets on manifolds, hydraulic and pneumatic systems, fuel lines, and compressed-air distribution. The MNPT x MNPT connection type makes it compatible with standard NPT-threaded pipe fittings found throughout plumbing and mechanical systems. Sold in a package quantity of four, it suits jobs requiring multiple plugs on a single system or stock replenishment for service vehicles.

Key Features

• 1/4 inch male NPT thread on both ends for straightforward port sealing
• Hex head design accepts standard open-end or adjustable wrenches

Compatibility

Designed as a standard MNPT hex plug for use with 1/4 inch NPT-threaded ports in industrial, plumbing, and mechanical piping assemblies.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system before installing or removing any threaded fittings. Apply thread sealant tape or pipe compound appropriate for the service fluid before threading the plug into the port. Tighten with a wrench to achieve a leak-free seal without over-torquing the fitting or the receiving thread.
