Threaded diameter is 50 mm below the metal hose connector to withstand high working pressure in the case of multi- threaded to the main thread when tightened after the two connectors on the inner and outer taper surface closely with a hermetic seal . Cone angle is generally Hydraulic hose fittings 60 degrees , 74 degrees is also useful . The structure , good sealing, but the installation must ensure two countertop concentricity. In order to solve practical engineering often seen repeated demolition, installation and easy concentric and other issues, can also be designed as conical connector mating with the ball .
