Midland Industries 44650LF Cored Square Head Plug 1/8 Mpt

Product Description

The MIDLAND INDUSTRIES 44650LF is a cored square head plug designed for use in plumbing, HVAC, and mechanical piping systems where a secure, leak-resistant closure is required. Manufactured from lead-free red bronze, this plug meets ANSI B16.15 dimensional standards and carries a 125 PSI pressure class rating. It features a 1/8 in MPT (male pipe thread) connection with a 1/8-27 thread specification. The cored design and square head allow for easy installation with a standard wrench or square-drive tool. Licensed plumbers and HVAC technicians working on potable water, steam, gas, or oil systems will find this plug compliant with lead-free material requirements.

This plug is rated for use with air, gas, oil, steam, and water, making it suitable across a wide range of residential and light commercial mechanical applications. Common install scenarios include capping unused branch ports on manifolds, sealing test ports on gas lines, and closing off low-pressure pipe ends in HVAC and plumbing rough-in work. Its compact profile fits tight spaces where larger fittings would interfere with adjacent components.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Always shut off and depressurize the system before removing or installing pipe plugs. Apply an appropriate thread sealant or PTFE tape to the male threads before installation, following local plumbing and mechanical code requirements. Do not over-torque bronze fittings, as the material is softer than steel and susceptible to thread damage under excessive force.
