O-ring face seal hose fittings is designed by ISO 12151-1 and SAE J516 section 18. Two standards is technically equivalent to the hose fittings.
ISO 12151-1 Types of ORFS hydraulic hose fittings including as follows:
Male hose fitting, straight (S)
Female swivel hose fitting straight Styles A (SWSA) and B (SWSB)
Female swivel hose fitting 45° elbow [short (SWE45S) and medium (SWE45M)]
Female swivel hose fitting 90° elbow [short (SWES), medium (SWEM), long (SWEL)
Applications for short, medium and long ISO 12151-1 hose fittings
The ORFS hose-fitting portion of a hose assembly shall be tested in accordance with ISO 19879, and the complete hose assembly shall be tested in accordance with ISO 6605.
“Hose fittings with O-ring face seal ends conform to ISO 12151-1, Connections for hydraulic fluid power and general use–– Hose fittings Part 1: Hose fittings with ISO 8434-3 O-ring face seal ends.”
