Prestolok's "elastic teeth" stainless steel grab ring technology was not only invented by but was perfected by Parker. These Prestolok brass fittings can be used with most thermoplastic and copper tubing. Male pipe threads come standard with white sealant pre-applied. While the male pipe thread swivels for precision positioning and installation in tight places, these are not recommended for applications that need a live swivel. Parker's Hose Barb fittings are available in both beaded barb and standard barb designs in a wide range of configurations and sizes. Parker's Hose Barbs are also available with SAE straight threads and Metric threads.
