Midland Industries 67508 Hex Bushing 3/4 Mpt X 3/8 Fpt Steel

Product Description

The MIDLAND INDUSTRIES 67508 is a black steel hex bushing designed to reduce a 3/4-inch male pipe thread (MPT) connection down to a 3/8-inch female pipe thread (FPT). The fitting is manufactured from steel with a black finish and conforms to ASME B16.14-1991 dimensional standards. It carries a pressure rating of 150/300 psi, making it suitable for moderate-pressure piping systems. The 1.06-inch hex allows standard wrench engagement for secure installation. At 0.94 inches in length, it is a compact fitting used by plumbers, pipefitters, and HVAC technicians to adapt threaded pipe connections in tight spaces.

This hex bushing is used in residential and light commercial gas, water, or air piping systems where a threaded line must be reduced from 3/4-inch to 3/8-inch. Typical install scenarios include gas appliance supply lines, compressed air distribution drops, and general plumbing branch connections. The black steel construction makes it common in natural gas and propane piping applications where black iron pipe is the standard material of choice.

Compatibility

Designed as a standard ASME B16.14 black steel threaded fitting compatible with 3/4-inch MPT and 3/8-inch FPT connections in black iron pipe systems used in gas, air, and water distribution applications.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians. Shut off gas or water supply and relieve system pressure before making or breaking any threaded connection. Apply appropriate thread sealant or PTFE tape to male threads per applicable code, including IFGC or IPC requirements for the specific service. Do not over-tighten; use a backup wrench on adjacent fittings to prevent stress on existing pipe runs.
