1 Scope This British Standard specifies the basic dimensions necessary to ensure interchangeability of hydraulic connectors and adaptors for connecting rigid and flexible tubing to hydraulic fluid power system components. Fourteen styles of adaptor and five styles of hose fitting are specified. Adaptors and hose fittings have been allocated style designation letters and female end fittings type designation letters, according to their shape and dimensions. For female ends, a conventional plain nipple is specified for face sealing and a nipple with a groove for “O”-ring sealing. The appropriate “O”-rings for use with the fittings and adaptors are also specified. A spherical seating is specified as an alternative to the female conical seating, provided that all other limiting dimensions are maintained. This standard specifies maximum working pressures but does not specify materials, production processes or dimensions that are not related to interchangeability.
NOTE 1 Hose fitting styles B, D, E and G may be made from swept elbow bends as specified in BS 5327.
NOTE 2 It is the responsibility of the designer to ensure that materials and production processes are compatible with the fluids to be encountered in service.
