SK Series

Aluminium pipes and quick fittings

Explore and discover all the products of the ST line

The experience gained from the SR Series led to the development of the new SK Series, the safe and quick solution for compressed air distribution. The line, composed of aluminum tubes Ø15, Ø18, Ø22, Ø28 mm, is assembled with nylon fittings. Tests show that the SK Series offers excellent resistance to stress caused by pressure changes due to water hammer and perfect durability against salt mist. Additionally, the SK Series significantly reduces assembly times.

Assembly

The first stage of assembling quick-connect fittings is simply inserting the fitting onto the tube.

1. Insert the tube into the fitting

The final assembly step for SK series quick-connect fittings: Once the tube is inserted into the fitting, a click will be heard, indicating the proper activation of the locking mechanism.

2. Push the fitting until it blocks

Fast

The SK Series reduces assembly times thanks to its quick-connect system, ensuring speed in setup and versatility in design, backed by the assurance of a complete system.

Safe

The SK Series assembly system is fast and simple but most importantly safe and reliable. The practical release tool allows you to detach the individual tubes securely, avoiding accidental disconnections.

Easy

Creating a compressed air distribution line has never been so easy. The quick-connect system of the SK Series fittings allows for the rapid installation of the compressed air distribution system without the need for welding or tightening of nuts.
