Midland Industries 35281CE Pex Male Npt Adapter 1 Inch

Product Description

The MIDLAND INDUSTRIES 35281CE is a cold expansion male pipe adapter designed for connecting 1-inch cold-expansion PEX tubing to 1-inch male NPT threaded fittings. Constructed from polyphenylsulfone (PPSU), this adapter delivers high heat resistance and long-term durability in demanding plumbing installations. It measures 2.3 inches in length, 1.45 inches in width, and 1.35 inches in height, and weighs 0.045 pounds. Plumbers and pipefitters use this fitting when transitioning between PEX distribution systems and NPT-threaded components such as valves, manifolds, or service connections.

This adapter is suited for residential and light commercial plumbing systems that use cold-expansion PEX pipe. The cold-expansion connection method requires an expansion tool to enlarge the pipe end and ring before insertion, creating a reliable, leak-resistant joint as the material contracts back to its original diameter. The male NPT end threads directly onto compatible female-threaded fittings, making this adapter a standard transition point in PEX distribution lines, fixture supply branches, and mechanical room piping.

Key Features

• Cold-expansion PEX connection on one end for a secure, tool-expanded joint
• 1-inch male NPT thread on the opposite end for direct connection to female NPT fittings
• Polyphenylsulfone (PPSU) construction for high heat resistance and chemical durability
• Compact form factor: 2.3 inches long, 1.45 inches wide, 1.35 inches tall
• Lightweight at 0.045 pounds, minimizing load on supply lines

Compatibility

Designed as an OEM-style replacement fitting for 1-inch cold-expansion PEX plumbing systems requiring a transition to 1-inch male NPT threaded connections.

Installation Notes

Installation is performed by licensed plumbers following applicable IPC and local plumbing code requirements. Shut off and depressurize the water supply before beginning work. Use a calibrated cold-expansion tool sized for 1-inch PEX to expand the pipe end and expansion ring before seating the fitting. Thread the male NPT end into the mating female-threaded fitting using appropriate thread sealant or PTFE tape per code requirements.
