Kwik Connect fittings have a unique oval-shaped collet, making it easier to grip, easier to connect and easier to disconnect. The rounded stainless teeth within the fittings are the secret to a perfect seal and a proprietary design minimises the wear on the tube, this allows for more frequent reuse of the tube and fittings. Kwik Connect fittings are not recommended for use with liquids other than water and food or beverage products.
