Parker 72338270 Push-to-connect Union Fitting 1/2 Inch Od

Product Description

The PARKER 72338270 is a push-to-connect union tube fitting designed for quick, tool-free connections in fluid and pneumatic line installations. Rated to 160 psi, the fitting joins two runs of 1/2-inch OD tubing without threading, soldering, or compression tools. The body is molded from bio-sourced Nylon 11, a renewable-origin polyamide known for chemical resistance, flexibility, and long service life in both liquid and air service. An EPDM O-ring provides the internal seal, making this fitting well suited for water, mild chemical, and general-purpose pneumatic applications. Plumbers, mechanical contractors, and HVAC service technicians install this fitting where fast, reliable tube connections are needed in tight spaces or during system retrofits.

This union fitting is used in residential and light commercial plumbing, pneumatic control lines, and fluid distribution systems where 1/2-inch OD tubing is the specified line size. Typical applications include potable water distribution, HVAC condensate and water lines, compressed air supply runs, and low-pressure fluid transfer systems. The push-to-connect design reduces installation time compared to traditional compression or threaded fittings, making it a practical choice for service calls and new construction alike. Fittings are sold in a package quantity of five.

Key Features

• Push-to-connect design allows tool-free, one-hand tube insertion for fast field installation
• 160 psi pressure rating suitable for a wide range of low-to-medium pressure plumbing and pneumatic applications
• Bio-sourced Nylon 11 body offers chemical resistance, flexibility, and a reduced environmental footprint versus petroleum-based nylons
• EPDM O-ring seal provides reliable performance in water and mild chemical service
• White body color aids visual identification and line tracing in multi-line installations
• Packaged in quantities of five for efficiency on larger jobs

Compatibility

Designed for use with 1/2-inch OD tubing in push-to-connect plumbing, pneumatic, and fluid distribution systems. Verify tubing OD, wall hardness, and system fluid compatibility with Nylon 11 and EPDM before installation.

Installation Notes

Shut off system pressure and depressurize the line fully before installing or removing any push-to-connect fitting. Cut tubing square with a proper tube cutter and deburr the end before insertion to ensure a leak-free seal against the O-ring. This fitting is typically installed by licensed plumbers or mechanical contractors and must meet applicable local plumbing codes and standards. Confirm the 160 psi pressure rating is not exceeded in the installed system.
