Midland Industries 66504 Reducer Hex Bushing 1/2 Mpt X 1/4 Fpt

Product Description

The MIDLAND INDUSTRIES 66504 is a reducer hex bushing designed to step down a 1/2-inch male pipe thread (MPT) connection to a 1/4-inch female pipe thread (FPT) connection. Constructed from steel with a zinc-plated finish, it provides corrosion resistance in demanding service environments. The bushing measures 0.8 inches in length with a 0.87-inch hex for wrench engagement. It carries a pressure rating of 150/300 psi and conforms to ASME B16.14-1991 dimensional standards. Plumbers, pipefitters, and HVAC technicians use this fitting to adapt between pipe sizes in gas, water, and compressed air systems.

This reducer hex bushing is suited for residential and light commercial piping applications where a threaded line must transition from a 1/2-inch NPT port to a 1/4-inch FPT connection. Common install scenarios include instrumentation taps, pressure gauge ports, drain connections, and branch line reductions. The zinc-plated steel construction makes it appropriate for galvanized steel piping assemblies and dry gas service. It ships in single-piece quantities, making it practical for both service calls and larger piping projects.

Key Features

• Steps down 1/2 in MPT to 1/4 in FPT in a single compact fitting
• Zinc-plated steel construction for corrosion resistance in galvanized piping systems
• Pressure rated to 150/300 psi per ASME B16.14-1991
• 0.87 in hex allows standard wrench engagement for controlled tightening
• Compact 0.8 in length minimizes added run in tight spaces
• Thread form: 1/2-14 NPT male x 1/4-18 NPT female

Compatibility

Designed as an OEM-style threaded fitting replacement for galvanized steel pipe assemblies using 1/2-inch and 1/4-inch NPT connections in plumbing, HVAC, and compressed air systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the line before disassembly or installation. Apply thread sealant tape or pipe compound to the male threads before assembly. Do not over-torque; tighten to a firm, leak-free seat and verify with a pressure test before returning the system to service.
