Parker A6CU6-MG Cross Tube Fitting 3/8 Inch Od

Product Description

The PARKER A6CU6-MG is a push-to-connect cross tube fitting designed for tube-to-tube connections in pneumatic and fluid handling systems. It accepts 3/8 inch OD tubing on all four ports and is constructed from polyoxymethylene (POM), a rigid engineering-grade thermoplastic known for chemical resistance and dimensional stability. Rated to 300 psi, this fitting is well-suited for compressed air lines, instrumentation tubing, and light fluid distribution circuits. Installation requires no tools for tube insertion, making it a fast, reliable choice for technicians building or servicing pneumatic panel assemblies and process control plumbing.

This cross fitting is used in applications where a single supply line must branch into multiple downstream circuits simultaneously. Common install scenarios include pneumatic control panels, automation equipment, HVAC control tubing runs, and light-duty fluid distribution manifolds. The four-port cross configuration allows a straight-through flow path with two lateral takeoffs, reducing the need for additional tee fittings and minimizing connection points in a run. The tan POM body is lightweight at 0.05 pounds, making it practical for panel-mounted or overhead tubing layouts.

Key Features

• Push-to-connect design accepts 3/8 inch OD tubing on all four ports with no tools required for insertion
• Rated to 300 psi for use in compressed air and light fluid service
• Polyoxymethylene (POM) body offers strong chemical resistance and dimensional stability
• Cross configuration allows one inlet and three outlets, or full four-way flow distribution
• Lightweight construction at 0.05 pounds suits panel-mount and overhead installations
• Tan color aids visual identification in multi-line tubing systems

Compatibility

Designed as an OEM-style push-to-connect replacement or new-installation fitting for pneumatic and fluid systems using 3/8 inch OD tubing.

Installation Notes

This fitting is typically installed by HVAC technicians, pneumatic system technicians, or instrumentation mechanics. Before servicing any connected tubing circuit, depressurize the system completely and verify zero pressure at the work point. Tubing ends should be cut cleanly and squarely with a tube cutter and deburred before insertion to ensure a proper seal. To release tubing, depress the collet ring while withdrawing the tube.
