Midland Industries 28182L Brass Reducing Coupling 3/8x1/8 in

Product Description

The MIDLAND INDUSTRIES 28182L is a brass reducing coupling designed to connect two threaded pipe sections of different diameters. It transitions from a 3/8-inch female thread on one end to a 1/8-inch female thread on the other, allowing a step-down connection in compressed air, gas, hydraulic, and fluid piping systems. The fitting is rated to 1200 psi and handles temperatures from -65 to 250 degrees F, making it suitable for demanding service environments. Thread specifications are 3/8-18 NPT on the larger end and 1/8-27 NPT on the smaller end. Plumbers, pipefitters, and HVAC technicians install this type of coupling during new construction and retrofit work where pipe size reductions are required.

This reducing coupling is used in residential and light commercial piping applications wherever a threaded step-down connection is needed. Typical scenarios include manifold assemblies, compressed air distribution lines, gas distribution headers, and instrumentation lines. Its brass construction makes it appropriate for use with aluminum, brass, bronze, copper, iron, and steel pipe. The compact dimensions allow installation in tight spaces common in mechanical rooms and equipment enclosures.

Key Features

• Rated to 1200 psi for use in compressed air, gas, and fluid systems
• Operating temperature range of -65 to 250 degrees F
• 3/8-18 NPT x 1/8-27 NPT thread configuration for reliable step-down connections
• Brass construction resists corrosion and is compatible with a wide range of pipe materials
• Compact form factor suits confined installation spaces

Compatibility

Compatible for use with aluminum, brass, bronze, copper, iron, and steel pipe in threaded piping systems requiring a 3/8-inch to 1/8-inch NPT reduction.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as brass fittings can crack under excessive torque.
