You will find SAE J1926 vs ISO 11926 fittings spec standards is the same and interchangeable.
SAE J1926 consists of the following parts, under the general title:
Connections for general use and fluid power Ports and stud ends with ASME B1.1 threads and O-ring sealing:
SAE J1926-1 Part 1: Port with O-Ring Seal in Truncated Housing
SAE J1926-2 Part 2: Heavy-Duty (S Series) Stud Ends
