JIC vs SAE Hydraulic Fittings, how to distinguish them?

JIC hydraulic fittings and SAE hydraulic fittings both play an important connecting role in the hydraulic system, but there are some differences between them in terms of standardization, design features and application areas. The following is a detailed comparison of the two:

Standard-setting organization：

JIC hydraulic fittings: follow the JIC (Joint Industrial Council, the United States Industrial Joint Committee) standards. The committee from the UN (Unified National) thread selected some specifications as their own special standards, these specifications are known as the JIC thread, and then applied to the manufacture of hydraulic fittings.
SAE hydraulic fittings: follow SAE (Society of Automotive Engineers) standards, a widely recognized industry standards organization whose standards are highly authoritative and influential in the automotive industry and related fields. Although the term “SAE hydraulic fittings” may not directly refer to a specific type of fitting, SAE standards do cover many aspects of hydraulic systems, including fitting size, performance and other requirements.

Design Features：

JIC hydraulic fittings: typically have a 74 degree flared fitting design, similar to tube fittings, but more often used for connections. jic fittings tend to have fine threads for high pressure, high sealing requirements.
SAE hydraulic fittings (assumed to be a specific type of fittings following the SAE standard): their design features may vary depending on the specific type, but generally follow the SAE standard requirements for size, performance, etc. The SAE standard emphasizes the interchangeability, durability, and reliability of the fittings to ensure stable operation in the complex and changing environment of the hydraulic system.

Application Areas：

JIC hydraulic couplings: widely used in various hydraulic systems, including construction machinery, metallurgical equipment, petrochemical, aerospace and other fields. Its high sealing and high pressure tolerance make it an ideal choice for high pressure and high temperature environments.
SAE hydraulic fittings: also applicable to a variety of hydraulic systems, but may be more related to the automotive industry. the wide application of SAE standards in the automotive industry means that SAE hydraulic fittings have an important position in the field of automobile manufacturing, repair and modification.

Check the marking:

Proper hydraulic joint products are usually labeled with the standards they follow or the manufacturer’s information. By looking at the markings on the fitting or related documents, you can initially determine whether it belongs to the JIC standard or SAE standard.
Compare sizes and specifications: Although there may be dimensional overlap between fittings of different standards, a careful comparison of key parameters such as thread size, pipe diameter, etc. can usually reveal significant differences.
