Parker A6UC6-MG Push-to-connect Union Fitting 3/8 in

Product Description

The PARKER A6UC6-MG is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid transfer systems. It accepts 3/8 inch OD tubing and creates a secure, tool-free connection rated at 300 psi. The fitting is constructed from polyoxymethylene (POM), a high-strength acetal thermoplastic that resists wear and chemical exposure in demanding service environments. HVAC technicians, plumbers, and pneumatic system installers use this style of fitting where fast, repeatable connections are required without threading or soldering.

This fitting is suited for residential and light commercial applications where 3/8 inch OD tubing runs require a straight union connection. Common install scenarios include pneumatic control lines, low-pressure fluid distribution, and equipment interconnects where push-to-connect convenience reduces labor time. The tan POM body is compatible with a range of compatible tubing materials used in these systems.

Key Features

• Compact, lightweight construction at 0.02 pounds

Compatibility

Designed as an OEM-style push-to-connect union fitting for use with 3/8 inch OD tubing in pneumatic and low-pressure fluid systems.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pneumatic system technicians depending on the application. Depressurize and isolate the system fully before disconnecting or installing any push-to-connect fitting. Ensure tubing ends are cut square and deburred before insertion to maintain a proper seal. Verify the tubing OD matches the fitting specification before assembly.
