High-Quality Construction Materials

• Threaded Body: Made from nickel-plated brass, providing excellent corrosion resistance and mechanical integrity.

• Push-in Sleeve & Gripper: Constructed using PBT and stainless steel for wear resistance and firm grip on the tube.

• Sealing Components: NBR seals ensure a tight, secure connection that prevents leakage under dynamic conditions.

This combination of materials guarantees long service life even in applications with vibration, temperature changes, or continuous movement.

Quick and Tool-Free Tube Installation

One of the standout features of the QSL-1/4-8 fitting is its push-in connection system, which allows users to insert 8 mm OD tubing securely by hand. The internal gripping claws hold the tube in place tightly, while the integrated O-ring ensures a leak-proof seal.

To release the tube, simply push back the blue release collar—making maintenance and rerouting fast and simple, even in field conditions.

Versatile Thread Compatibility

The 1/4-inch external thread follows BSPP (British Standard Pipe Parallel) standard, making it suitable for a wide range of pneumatic valves, cylinders, manifolds, and air tools with matching threaded ports.

The threads are equipped with a pre-applied sealing coating, removing the need for additional sealing tape or paste in most applications and reducing installation time.
