Parker A6EU6-MG Push-to-connect Union Fitting 3/8 in Od

Product Description

The PARKER A6EU6-MG is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from polyoxymethylene (POM), a high-strength engineering thermoplastic, this fitting accepts 3/8-inch outside diameter tubing on both ends and creates a secure, tool-free connection. Rated to 300 psi, it is suited for compressed air lines, instrumentation tubing runs, and similar low-to-medium pressure plumbing applications. Licensed plumbers, HVAC technicians, and mechanical contractors install these fittings where a reliable inline union is needed without threading or soldering.

This fitting is used in residential and light commercial mechanical systems where tubing runs require inline connections, repairs, or extensions. Common applications include pneumatic control lines, process instrumentation, and compressed air distribution. The push-to-connect design allows rapid assembly in tight spaces, making it practical for service work and new installation alike. The tan-colored POM body resists corrosion and is compatible with a broad range of non-aggressive fluids and gases.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure retention at 300 psi
• Accepts 3/8-inch OD tubing on both ends for an inline union connection
• Polyoxymethylene (POM) construction provides chemical resistance and dimensional stability
• Lightweight at 0.02 pounds, minimizing load on tubing runs
• Tan body color aids quick visual identification during installation and inspection

Compatibility

Designed as an OEM-style push-to-connect union fitting for 3/8-inch OD tubing in pneumatic, instrumentation, and fluid-distribution plumbing systems.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical technicians. Depressurize and isolate the system completely before disconnecting or installing any push-to-connect fitting. Ensure tubing ends are cut cleanly and squarely with no burrs or ovality, as irregular tube ends can compromise the internal collet seal. Follow applicable codes, including the IPC and IFGC where relevant, and verify that the connected tubing material and fluid media are compatible with POM at the system operating pressure.
