Fittings
UNIC is a manufacturer of fittings, components used in pneumatic systems for assembling plastic tubes. The tubes are securely attached to the fitting by tightening a collar, ensuring a perfect seal. These fittings are particularly suitable for environments where vibrations or extreme climatic conditions may cause changes to the tube’s characteristics over time.
