Midland Industries 36264 3/4 Pex X 3/4 Female Npt Adapter

Product Description

The MIDLAND INDUSTRIES 36264 is a female adapter fitting designed to transition a 3/4-inch PEX line to a 3/4-inch female NPT threaded connection. Constructed from polyphenylsulfone (PPSU), this fitting delivers high heat and chemical resistance suited to potable water and hydronic plumbing systems. PPSU fittings are a common choice where corrosion resistance and long-term durability are priorities over metal alternatives. Licensed plumbers install this adapter when connecting PEX tubing to threaded valves, manifolds, or fixtures that require a standard female NPT port.

This adapter is used in residential and light commercial plumbing installations where PEX tubing meets a threaded iron pipe or NPT-ported component. Typical applications include domestic hot and cold water distribution, radiant heating supply and return connections, and fixture rough-in work. It is appropriate for use with 3/4-inch PEX tubing systems where a female NPT termination is required at a valve, tee, or transition point.

Key Features

• Polyphenylsulfone (PPSU) construction for corrosion resistance and high-temperature performance
• 3/4-inch PEX connection on one end for use with standard PEX tubing
• 3/4-inch female NPT thread on opposing end for connection to threaded components
• Compact profile suited to tight rough-in spaces
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement and standard fitting for 3/4-inch PEX plumbing systems requiring a female NPT threaded transition point.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before beginning work. Use the appropriate PEX crimping, clamp, or expansion tool as required by the PEX system type being used. Do not overtighten the NPT threaded connection; use thread sealant tape or compound rated for the intended service.
