Midland Industries 35263CE Pex Female Adapter 1/2 in

Product Description

The MIDLAND INDUSTRIES 35263CE is a cold-expansion PEX female adapter designed to transition a 1/2-inch cold-expansion PEX line to a 1/2-inch female NPT threaded fitting. Constructed from polyphenylsulfone (PPSU), this adapter delivers high heat and chemical resistance suited for potable water and hydronic plumbing systems. At 0.02 pounds, it is a lightweight, single-piece fitting intended for professional plumbing installations where a secure, code-compliant PEX-to-threaded connection is required. Licensed plumbers and pipefitters are the primary installers for this type of fitting.

This adapter is used in residential and light commercial plumbing systems that rely on cold-expansion PEX pipe, commonly associated with PEX-a tubing and expansion-style installation methods. It is suited for potable water distribution lines, radiant heating supply and return connections, and manifold terminations where a female NPT threaded port is needed. The 1/2-inch by 1/2-inch sizing makes it a standard choice for branch lines feeding fixtures and valves throughout a structure.

Key Features

• Cold-expansion PEX connection on one end for use with PEX-a expansion tooling
• 1/2-inch female NPT threaded port for connection to male-threaded valves, manifolds, or fittings
• Polyphenylsulfone (PPSU) construction offers high thermal resistance and durability in plumbing environments
• Compact form factor at 1.5 inches in length and 1.15 inches in width
• Lightweight at 0.02 pounds, minimizing load on pipe runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for cold-expansion PEX-a plumbing systems using 1/2-inch pipe diameter with 1/2-inch female NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before making any connections. The cold-expansion end requires a compatible PEX expansion tool and expansion ring sized for 1/2-inch PEX-a pipe. Apply thread sealant or PTFE tape to the male NPT fitting being joined before threading into the female NPT port.
