Anderson Metals 756114-06 Brass Square Head Plug 3/8-18 Mnpt

Product Description

The ANDERSON METALS 756114-06 is a brass square head pipe plug designed to seal threaded pipe openings in a wide range of fluid and gas systems. It features a 3/8-18 male NPT (MNPT) thread and is rated to 1,000 psi, making it suitable for demanding service conditions. The square head drive allows installation and removal with standard wrenches without the risk of rounding that can occur with internal-drive plugs. At 0.07 pounds, this is a compact, low-profile fitting intended for use by plumbers, pipefitters, HVAC technicians, and gas service professionals working on both new installations and service calls.

This plug is approved for use with potable water, grease, fuels, LP gas, and natural gas systems. It is commonly installed to cap off unused tee or cross outlets, block test ports after pressure testing, or seal branch lines that are temporarily or permanently taken out of service. The brass construction offers good corrosion resistance across these varied media, making it appropriate for both residential and light commercial piping applications where threaded pipe fittings are standard practice.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas service technician in accordance with applicable local plumbing and gas codes, including IPC and IFGC requirements. Always depressurize and isolate the line before removing or installing pipe plugs. Apply an appropriate thread sealant or PTFE tape rated for the service medium before threading the plug in. Do not over-drive the plug, as brass threads can be damaged by excessive force.
