Parker 6302 56 60WP2 Push-to-connect Union 1/4x3/8 in

Product Description

The PARKER 6302 56 60WP2 is a push-to-connect union tube fitting designed to join two tube runs of different outside diameters without the need for tools or additional hardware. Constructed from polymer, it handles working pressures up to 230 psi. The fitting accepts 1/4 inch OD tube on one end and 3/8 inch OD tube on the other, making it a practical solution for reducing or transitioning tube sizes in a single inline connection. It is installed by HVAC technicians, plumbers, and refrigeration mechanics in low-pressure fluid and pneumatic line applications where quick, reliable tube connections are required.

This union fitting is suited for residential and light commercial applications where push-to-connect fittings are specified for compressed air lines, water supply runs, or other compatible low-pressure tubing systems. The reducer-style union eliminates the need for threaded adapters or separate reducers at the joint, simplifying routing when transitioning between 1/4 inch and 3/8 inch OD tubing. It is commonly encountered in HVAC condensate drain lines, pneumatic control circuits, and plumbing supply runs where polymer fittings are acceptable by local code.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and secure grip without solder, flare, or compression tools
• Reducer union configuration joins 1/4 inch OD and 3/8 inch OD tubing in a single fitting
• Polymer construction provides corrosion resistance in wet or humid environments
• Rated for working pressures up to 230 psi
• Compact body measures approximately 1.3 inches in length and height with a 0.63 inch width

Compatibility

Designed as an OEM-style push-to-connect union replacement for systems using 1/4 inch and 3/8 inch OD tubing where polymer push-fit fittings are approved for the application and operating pressure.

Installation Notes

Installation is performed by a licensed plumber, HVAC technician, or qualified mechanic. Before connecting or disconnecting any fitting, depressurize and lock out the line per applicable safety procedures and local codes. Ensure tube ends are cut cleanly and squarely with a tube cutter and are free of burrs before insertion to achieve a proper seal. Verify that the polymer fitting is rated for the specific fluid media and temperature range present in the system before use.
