Midland Industries 79500 Aluminum Pipe Bushing 1/4 Mpt X 1/8 Fpt

Product Description

The MIDLAND INDUSTRIES 79500 is an aluminum pipe bushing designed to reduce a 1/4-inch male pipe thread (MPT) connection to a 1/8-inch female pipe thread (FPT) port. This fitting is used to adapt piping or tubing runs where a threaded size reduction is needed between two threaded components. Constructed from aluminum, the 79500 offers corrosion resistance and a lightweight profile suited for low-pressure piping systems. The 1/4-18 thread specification on the male end conforms to standard NPT thread form. Plumbers, pipefitters, and HVAC technicians install this type of bushing as a straightforward inline size reducer in pneumatic, fluid, or gas distribution lines where aluminum fittings are appropriate.

This bushing is applicable in residential and light commercial piping installations where a threaded size transition is required. It fits directly into a female-threaded port or coupling, accepting a 1/8-inch FPT line on the opposite end. Typical use cases include pneumatic control lines, compressed air distribution, and low-pressure fluid systems that specify aluminum fittings. Its compact bushing form allows the connection to be made without adding significant length to the assembly.

Key Features

• Aluminum construction for corrosion resistance and lightweight handling
• 1/4-inch MPT inlet reduces to 1/8-inch FPT outlet for inline size transitions
• 1/4-18 NPT thread form on the male end for standard thread compatibility
• Compact bushing profile minimizes added length in tight piping assemblies
• Suitable for low-pressure pneumatic and fluid piping applications

Compatibility

Designed as a standard threaded pipe bushing for use in aluminum fitting assemblies requiring a 1/4-inch MPT to 1/8-inch FPT size reduction in low-pressure piping systems.

Installation Notes

Installation is performed by plumbers, pipefitters, or HVAC technicians using standard pipe wrenches or fitting wrenches. Depressurize and isolate the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads per the system requirements and local plumbing code. Avoid overtightening, which can crack aluminum fittings or distort threads.
