Parker 72338437 Union Y Fitting 1/4 Inch Od Nylon 11

Product Description

The PARKER 72338437 is a push-to-connect Union Y tube fitting designed for tube-to-tube connections in fluid handling systems. It accepts 1/4 inch OD tubing on all three ports and locks tubing in place without tools, enabling fast, reliable branch connections in pneumatic and low-pressure liquid lines. The body is molded from bio-sourced Nylon 11, a material known for flexibility, chemical resistance, and durability in demanding environments. EPDM O-rings provide the primary seal. Rated at 230 psi, this fitting is well suited for applications where a Y-branch connection is needed without soldering, threading, or compression hardware.

This fitting is used in pneumatic tubing runs, fluid distribution lines, and light industrial plumbing where 1/4 inch OD tubing is routed into a three-way branch. Its push-to-connect design makes it appropriate for installations requiring frequent service access or where tool-free assembly is a priority. The white Nylon 11 body is compatible with a range of media handled in clean fluid and pneumatic circuits. It ships in a package quantity of 10, making it practical for multi-point installations or service van stocking.

Key Features

• Union Y configuration creates a three-port branch from a single inline connection
• Bio-sourced Nylon 11 body offers chemical resistance and flexibility
• EPDM O-ring seals rated for a broad range of media
• 230 psi pressure rating for pneumatic and fluid service
• Accepts standard 1/4 inch OD tubing on all three ports

Compatibility

Designed as an OEM-style push-to-connect replacement or addition for pneumatic and fluid systems using 1/4 inch OD tubing.

Installation Notes

Push-to-connect fittings are installed by cutting tubing squarely and inserting it fully into the fitting until it seats against the internal stop. Depressurize and de-energize any pneumatic or fluid line completely before disconnecting or installing fittings. To release tubing, depress the collet release ring while pulling the tube out. Verify the tube OD and wall condition before installation, as out-of-round or scored tubing can compromise the seal.
