Midland Industries 706109-06 Brass Pipe Plug 3/8 Mpt

Product Description

The MIDLAND INDUSTRIES 706109-06 is a square head pipe plug designed to seal threaded pipe ends and ports in plumbing and mechanical systems. Manufactured from lead-free brass, this plug uses a 3/8-18 male pipe thread (MPT) and measures 0.75 inches in length. The square head drive profile allows installation and removal with a standard wrench or socket, making it a practical choice for service work where plugging an open line quickly and securely is the goal. Licensed plumbers and pipefitters install this type of fitting in potable water systems, hydronic lines, compressed air, and light commercial piping applications.

This plug is suited for use in residential and light commercial piping systems where a 3/8-inch NPT port needs to be sealed. It is rated for use with brass or steel pipe. The lead-free brass construction satisfies regulatory requirements for fittings used in drinking water systems under state and federal lead-free mandates. The compact dimensions make it a standard stocking item for service vans, mechanical rooms, and plumbing supply carts.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply or depressurize the line before installing or removing any threaded fitting. Apply thread sealant tape or compound compatible with the system fluid before threading the plug in by hand, then tighten with a wrench. Do not overtighten, as brass threads can be damaged by excessive torque.
