Midland Industries 35238CE Reducing Pex Coupling 1 in X 1/2 in

Product Description

The MIDLAND INDUSTRIES 35238CE is a cold-expansion reducing coupling designed for PEX plumbing systems that require a transition from a 1-inch line down to a 1/2-inch line. The fitting uses cold-expansion PEX connections on both ends, meaning installation requires an expansion tool to flare the PEX tubing before seating the fitting. The body is molded from polyphenylsulfone (PPSU), a high-performance thermoplastic known for its resistance to heat, chlorinated water, and mechanical stress. This coupling is installed by licensed plumbers and experienced pipe fitters during new construction and retrofit work in residential and light commercial potable water distribution systems.

This fitting is suited for in-wall and in-floor PEX installations where a branch line or fixture supply drops from a 1-inch main run to a 1/2-inch sub-run. Cold-expansion PEX fittings are commonly used in systems that follow ASTM F1960 connection standards. The PPSU material is compatible with both hot and cold water supply lines, making it appropriate for domestic water distribution wherever a reducing transition is required between those two pipe sizes.

Key Features

• Reduces from 1-inch cold-expansion PEX to 1/2-inch cold-expansion PEX in a single fitting
• Polyphenylsulfone (PPSU) construction offers strong resistance to heat, pressure, and chlorine
• Cold-expansion connection type provides a secure, leak-resistant mechanical joint without open flame or solvents
• Compact profile at approximately 2.05 inches in length, suitable for tight framing bays and utility chases
• Low unit weight of 0.03 pounds reduces load in overhead or multi-fitting assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for cold-expansion PEX plumbing systems using 1-inch and 1/2-inch ASTM F1960-compatible tubing and tooling.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines for PEX piping systems. Shut off the water supply and depressurize the line before cutting or modifying any pipe. A proper cold-expansion tool sized for both 1-inch and 1/2-inch PEX is required to flare the tubing ends before fitting insertion. Allow the expanded ring to recover fully around the fitting before pressurizing the system.
