Midland Industries LF121-12 Cored Hex Head Plug 3/4 Mpt

Product Description

The MIDLAND INDUSTRIES LF121-12 is a cored hex head plug designed for use in brass or steel pipe systems. Manufactured from lead-free brass, this plug threads into a 3/4-inch male pipe thread (MPT) port and measures 0.94 inches in length with a 1.06-inch hex. The cored design allows for future tap-out or blowdown applications without full removal of the plug. At 0.142 pounds, it is a compact, durable fitting suited for plumbing, HVAC, and industrial piping installations where lead-free compliance is required.

This plug is intended for use in residential and commercial piping systems that require a serviceable or temporary closure on a 3/4-inch MPT port. Typical applications include capping unused branch outlets, test ports, and access points on brass or steel pipe assemblies. Its lead-free brass construction makes it appropriate for potable water systems where lead-free material compliance is mandated by local plumbing codes.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before installing or removing this fitting. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with local plumbing codes such as IPC before threading into the female port. Do not overtighten, as brass threads can be damaged by excessive torque.
