You will often find writting of SAE ORB fittings in North America countries, they often choose SAE J514 and SAE J1453 standard dimensions, with the smae UNF thread fittings and different sealing methods.
SAE J1926 pressure rating as follow:
SAE J1926-2 fitting heavy duty S series stud end, be used at working pressures up to 63 MPa for
nonadjustable stud ends and up to 40 MPa for adjustable stud ends.
SAE J1926-3 fittings light duty L series stud end, be used at working pressures up to 40 MPa for
nonadjustable stud ends and up to 31 .5 MPa for adjustable stud ends.
SAE J1926 torque value as follows:
SAE J1926-2 ORB fitting qualification torque value from 10 to 370N.m.
SAE J1926-3 ORB fitting qualiication torque value from 8 to 300N.m.
SAE port fittings has connection types as follows:
ORFS tube to ISO 11926 fitting
These o-ring seal tube fittings is often found in caterpillar, John deere, bobcat etc heavy duty equipment and Case tractor.
