Midland Industries 28107 Brass Hex Bushing 1/2 X 3/8 Nptf

Product Description

The MIDLAND INDUSTRIES 28107 is a brass hex bushing designed to reduce a 1/2-inch male NPTF thread to a 3/8-inch female NPTF thread in piping systems. It measures 1 inch in length with a 0.87-inch hex for standard wrench engagement. Rated to 1200 psi, this fitting handles the pressure demands common in compressed air, hydraulic, and fluid-transfer lines. The thread specification is 1/2-14 x 3/8-18. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting as part of threaded pipe assemblies requiring a step-down transition between pipe sizes.

This hex bushing is suited for both residential and commercial piping applications where a male-to-female NPT reduction is needed. The NPTF thread form provides a pressure-tight seal without relying solely on thread sealant, making it appropriate for higher-pressure service. It is compatible with brass, bronze, copper, steel, aluminum, and iron pipe systems. Typical install scenarios include gas distribution headers, compressed air manifolds, hydraulic circuits, and plumbing supply lines operating within its rated temperature range of -65 to 250 degrees F.

Key Features

• 1/2-inch male NPTF x 3/8-inch female NPTF thread configuration for inline pipe size reduction
• Rated to 1200 psi for use in pressurized fluid and gas systems
• Temperature range of -65 to 250 degrees F suits a wide range of service environments
• 0.87-inch hex allows engagement with standard open-end or adjustable wrenches
• Brass construction offers corrosion resistance and compatibility with multiple pipe materials
• Thread specification: 1/2-14 x 3/8-18 NPTF

Compatibility

Designed for use with brass, bronze, copper, steel, aluminum, and iron pipe systems using standard NPTF threaded connections.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads unless the NPTF taper seal is relied upon alone, following the system manufacturer and applicable code guidance. Do not overtighten; use a wrench on the hex flats only and avoid applying torque to connected pipe or equipment.
