These fittings are one-quarter turn fittings (meaning they require only a quarter turn to connect). They are typically seen in low to medium pressure air and water hose assemblies. These fittings are versatile across many industries and a convenient way to quickly connect hoses of different diameters. This is capable because all sizes up to 1” interchange with each other. All our Universal Air Hose fittings are rated to 150 psi.

To connect, push two couplings together with a quarter twist. Couplings have a safety clip and lanyard to prevent accidental disconnection.
