Parker® Prestolok Nylon Push-to-Connect Fittings
Prestolok Composite Fittings are 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. Prestolok composite should not be used for live swivel applications. Body and collar are made of glass reinforced Nylon 6.6, gripping ring is stainless steel, and D seal and O-rings are Nitrile.
