Cross Fittings

Equal push-in cross fittings (4-way union crosses) are compact pneumatic quick-connect components designed to divide a single air supply line into three equal streams or connect four pneumatic tubes of the same outer diameter (OD) at a 90-degree intersection.

Our union crosses feature push-to-connect collets on all four ports, enabling fast, tool-free installation and reliable sealing for flexible tubing made of polyurethane (PU), polyamide (PA/Nylon), and polyethylene (PE).

Key Advantages & Technical Features:

• Equal Port Sizing: Designed for seamless connection of four identical tubing sizes, ranging from 4 mm to 16 mm outer diameter.
• Quick Tool-Free Assembly: Stainless steel lock claws grip the tubing securely, while high-grade NBR O-rings ensure leak-free operation under pressures up to 10 bar.
• Durable Construction: Lightweight, impact-resistant PBT plastic body combined with nickel-plated brass release rings for long service life in industrial environments.
• Optimal Airflow: Precision internal geometry minimizes pressure drop across all four distribution ports.
