Parker 72338205 Push-to-connect Union Tee 3/8 Inch Od

Product Description

The PARKER 72338205 is a push-to-connect union tee tube fitting designed for fast, tool-free connections in fluid and pneumatic distribution lines. Constructed from bio-sourced Nylon 11, this tee fitting handles working pressures up to 160 psi and connects tubing with a 3/8 inch outside diameter. The union tee configuration allows three-way flow splitting or combining from a single inline position. EPDM o-rings provide the internal seal, making this fitting compatible with a range of water-based and mild chemical media. It is sold in a package quantity of 10 units. Plumbers, HVAC technicians, and fluid system installers use this fitting for clean, repeatable connections without soldering, compression ferrules, or additional tools.

This fitting is suited for residential and light commercial plumbing, HVAC condensate and process lines, and pneumatic distribution systems where push-to-connect speed and leak-free performance are priorities. The 3/8 inch OD size is common in tubing runs for water treatment, reverse osmosis systems, and low-pressure pneumatic circuits. The white Nylon 11 body handles environments where corrosion resistance and light weight matter more than metal construction. Installers working with polyethylene or nylon tubing in tight spaces benefit from the stab-in connection style, which allows rapid assembly and repositioning during rough-in work.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Bio-sourced Nylon 11 body offers corrosion resistance and reduced environmental footprint versus petroleum-based plastics
• EPDM o-ring seals suit water-based and mild chemical service
• 160 psi working pressure rating
• Union tee configuration supports three-way inline flow splitting
• Package quantity of 10 units per order

Compatibility

Designed for use with tubing having a 3/8 inch outside diameter. Confirm tubing OD, wall thickness, and media compatibility with Nylon 11 body and EPDM o-ring materials before installation.

Installation Notes

Push-to-connect fittings are installed by cutting tubing square, deburring the cut end, and inserting it fully into the fitting collet until it seats against the internal stop. Depressurize and drain the line completely before servicing or removing any fitting. Verify the tubing OD tolerance and roundness meet the fitting manufacturer specifications to ensure a leak-free seal. Follow applicable plumbing and pneumatic codes, including IPC or local equivalents, for pressure rating and media suitability requirements.
