Parker 72338452 Push-to-connect Union Y 1/2 Inch Od

Product Description

The PARKER 72338452 is a push-to-connect union Y tube fitting designed for tube-to-tube connections in fluid handling systems. It accepts 1/2 inch OD tubing on all three ports and uses a tool-free push-in connection mechanism for fast, reliable assembly. The body is constructed from bio-sourced Nylon 11, a renewable-resource polyamide known for chemical resistance and flexibility across a range of operating conditions. EPDM o-rings provide a secure, leak-resistant seal. The fitting is rated to 160 psi and ships in a package quantity of 5 units.

This fitting is suited for residential and light commercial plumbing, pneumatic, or fluid transfer applications where a three-way branch connection is required. It is commonly installed in water treatment systems, air lines, and process tubing runs where quick assembly and disassembly are priorities. The white Nylon 11 construction makes it appropriate for potable water and other applications requiring non-metallic, corrosion-free components. Plumbers, HVAC technicians, and industrial piping mechanics routinely specify push-to-connect fittings of this type to reduce installation time on tubing runs.

• EPDM o-rings deliver a reliable seal across a broad range of fluid media
• Rated to 160 psi working pressure
• Union Y configuration enables a single inline branch split without additional adapters
• Packaged in quantities of 5 for efficient stocking and job-site use

Compatibility

Designed for use with 1/2 inch OD tubing in push-to-connect tube-to-tube fitting applications. Verify tubing material and system pressure and temperature ratings before installation.

Installation Notes

Shut off and depressurize the system completely before removing or installing any push-to-connect fitting. Ensure tubing ends are cut square and deburred to the full insertion depth marked on the tube; improper insertion is the leading cause of push-to-connect leaks. Confirm that the tubing OD and wall hardness are compatible with push-to-connect retention collets before pressurizing. Plumbers and fluid system mechanics should verify local code compliance for the intended service application.
