    These O-rings are specifically designed for use with a wide range of 1/4", 3/8", and 1/2" quick connect couplers used in water/liquid transfer, hydraulic service, compressed air, and vacuum applications. O-rings ensure your hydraulic couplers and fittings maintain optimal performance and do not excessively leak fluid upon connection or disconnection.

    Viton® O-rings are brown in color and rated to a maximum temperature of 400° F.
