Nominal tube OD is shown for the standard inch sizes and the conversion to equivalent millimeter sizes. Figures are for reference only, as any boss can be used for a tubing size depending upon other design criteria. See SAE J846 for more information.

SAE J1926-1, predominantly used in North America, utilizes UN/UNF threads coupled with O-ring sealing to secure connections and prevent leakage. On the other hand, ISO 11926-1, widely adopted globally, especially in Europe, employs metric threads, aligning with international standards to support global equipment compatibility.

Q IS0 IS0 11926=3:1995(E) IS0 48. O-rings shall conform to the dimensions given in table4 and shall meet or exceed the quality re- quirement grade N of IS0 3601-3. 7.1.3 Procedure 7.1.3.1 Thread lubrication

SAE J1926-1 — SAE Straight Thread O-ring Port. Conforms to MS16142. Does NOT conform to MS33649 (8). SAE J1926-1 is the same to ISO 11926-1 standard for O-Ring Boss (ORB) Fittings. Nominal tube OD is shown for the standard inch sizes …

Unlike tapered threads, parallel thread ports do not require sealing by the threads. The seal is obtained by other means, typically an elastomeric seal. When assembled properly, parallel thread ports provide the best leak-free port connection available. DIN Metric flat face (ISO 9974).

SAE J1926-1 is SAE Straight Thread O-ring Port Conforms to MS16142. Does NOT conform to MS33649 (8). SAE J1926-1 is the same to ISO 11926-1 standard. ISO 11926-1 is International standard organization from a worldwide federation of national standards bodies.

Nov 9, 2023 · The specifications for SAE J1926 and ISO 11926 fittings demonstrate their compatibility and interchangeability. These standards fall under the umbrella of “Connections for general use and fluid power Ports and stud ends with O-ring sealing,” where SAE J1926 utilizes ASME B1.1 threads, and ISO 11926 uses ISO 725 threads.

Connections for general use and fluid power — Ports and stud ends with ISO 725 threads and O-ring sealing — Part 1: Ports with O-ring seal in truncated housing. This publication was last reviewed and confirmed in 2021. Therefore this version remains current.

This part of ISO 11926 specifies dimensions for ports with inch threads complying with ISO 725 for use with the adjustable and non-adjustable stud ends detailed in ISO 11926-2 and ISO 11926-3. It also specifies test methods and the designation of these ports.

Sep 27, 2023 · Understanding these specific technical details is fundamental in ensuring the appropriate selection and use of O-ring ports conforming to the SAE J1926-1 (ISO 11926-1) standard. Adequate adherence to these standards guarantees not only the efficiency and functionality of the ports but also their compatibility and longevity in various applications.
