Anderson Metals 756123-0402 Hex Plug 1/4-18 X 1/8-27 Mnpt Brass

Product Description

The ANDERSON METALS 756123-0402 is a hex plug fitting machined from lead-free brass for use in piping systems that carry potable water, grease, fuels, LP gas, and natural gas. It features a reducing male thread configuration — 1/4-18 MNPT on the larger end and 1/8-27 MNPT on the smaller end — allowing technicians to close off or step down a threaded port in a single fitting. The 1000 psi maximum working pressure rating makes it suitable for moderate-pressure service lines. Its lead-free brass construction meets potable water compliance requirements, making it appropriate for both plumbing and mechanical systems.

This hex plug is suited for residential and light commercial plumbing, HVAC refrigerant-side accessories, gas distribution piping, and lubrication systems. The MNPT thread standard is compatible with standard tapered pipe threads found across a wide range of valves, manifolds, equipment ports, and pipe fittings. Licensed plumbers and HVAC-R technicians typically install this fitting when reducing, capping, or transitioning threaded ports in low-to-moderate pressure service applications.

Key Features

• Lead-free brass construction — compliant for potable water applications
• 1/4-18 x 1/8-27 male MNPT reducing thread configuration
• 1000 psi maximum working pressure rating
• Hex-body profile accepts standard wrench for torque-controlled installation
• Rated for use with potable water, grease, fuels, LP gas, and natural gas

Compatibility

Designed for use with potable water, grease, fuels, LP gas, and natural gas piping systems using standard MNPT tapered pipe thread connections.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC-R or gas service technicians. Shut off the water supply or gas service and depressurize the line before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with local plumbing and mechanical codes, including IPC and IFGC requirements where applicable. Do not over-tighten; use a calibrated wrench on the hex body and avoid excessive force that could crack the fitting or damage the mating port.
