A compact one piece push-to-connect fitting. All items in the Prestolok
composite range are silicone free. The stainless steel gripping ring
ensures excellent tube retention while the D seal within the fitting
provides a positive seal on the O.D. of the tube, in both static and
dynamic positions, due to an optimized design of the fitting cavity.
