6mm Cross Pneumatic Connector, 4-Way Equal Union Push-In Fitting for Air Hose

The 6mm Cross Pneumatic connector is a four-way equal union push-in fitting designed to split a single compressed-air line into four branches at precise 90-degree angles. Each of the four ports accepts standard 6mm outside-diameter tubing, making the fitting compatible with polyethylene (PE), nylon, and polyurethane (PU) hoses commonly used in industrial compressed-air circuits. The cross-shaped configuration allows one input to be distributed evenly across four outputs, which is useful in automation systems, robotic equipment, packaging machinery, and laboratory pneumatic setups where simultaneous branching is required.

The fitting body is made from a durable composite material and uses an internal locking mechanism that grips the tube as soon as it is pushed into the port. This push-to-connect design eliminates the need for adhesives, clamps, or additional sealing tape, and it allows tubing to be installed or removed quickly during maintenance. To release a tube, the plastic release collar at the port is pressed down and the hose is pulled out, simplifying service and reducing downtime for technicians.

The 6mm Cross Pneumatic connector is rated for a working pressure of 0 to 1 MPa and an ambient temperature range of 0°C to 60°C. Its four ports are arranged at exact 90-degree angles so that airflow is directed evenly through the branches, helping to reduce pressure drop and maintain consistent performance across the circuit. The fitting is compact and lightweight, and it is compatible with other 6mm pneumatic fittings, making it a practical component for both new builds and replacement applications.
