The A-Series (Grey) Pneumatic Fittings are premium-quality push-in fittings designed for quick, secure, and leak-proof connections in compressed air systems. Manufactured from high-grade engineering plastic (typically PBT or nylon) with brass or stainless steel threaded inserts, these fittings are known for their excellent chemical resistance, durability, and ease of installation.

Tailored for use in industrial automation, machine tools, packaging systems, robotics, and air handling units, the A-Series fittings come in a distinct grey color for easy identification and aesthetic integration. These fittings support metric tubing and are available in a wide range of configurations such as male/female connectors, elbows, tees, crosses, reducers, and plugs—providing complete flexibility in designing or modifying pneumatic circuits.

Each fitting features a reliable gripping mechanism with stainless steel teeth and an internal O-ring that ensures a tight seal under pressure, while allowing quick tube release with the press of a collet. These fittings conform to international standards and are ideal for applications where clean, efficient air flow and easy maintenance are required.
