Anderson Metals 756125-06 Brass Hex Plug 3/8-18 Mnpt

Product Description

The ANDERSON METALS 756125-06 is a brass hex plug designed to seal pipe ends and unused port openings in pressurized systems. Threaded with a 3/8-18 male NPT connection, this fitting installs by hand and torques with a standard wrench for a secure, leak-resistant seal. It carries a pressure rating of 1000 psi and is suited for a wide range of media including potable water, grease, fuels, LP gas, and natural gas. The hex body provides a reliable wrench grip for proper installation torque. Plumbers, pipefitters, and HVAC technicians commonly use hex plugs during system maintenance, pressure testing, and port isolation.

This hex plug is appropriate for residential and light commercial piping applications where an MNPT end closure is required. Typical uses include capping unused tee or cross ports, plugging test points after pressure checks, and sealing branch connections that are no longer in service. The brass construction offers corrosion resistance across the rated media types, making it a practical choice for gas lines, water supply systems, and lubrication circuits.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and IFGC or IPC requirements where relevant. Shut off and depressurize the system completely before installing or removing any pipe plug. Apply appropriate thread sealant or PTFE tape to the male threads before installation. Do not overtighten brass fittings, as the material is subject to stress cracking under excessive torque.
