SAE joints (SAE Connector) refers to the American Society of Automotive Engineers (SAE, Society of Automotive Engineers) standard hydraulic, pneumatic or electrical connectors, the following is the meaning of the standard SAE joints common specifications, as well as frequently asked questions about the detailed introduction.
SAE Connector is a hydraulic, pneumatic or electrical connector that meets the standards of SAE, Society of Automotive Engineers, and is widely used in automotive, construction machinery, aerospace and industrial equipment etc. The main features of SAE connector are standardization, high sealing, high pressure resistance and interchangeability to ensure the reliable connection of equipment produced by different manufacturers. The main features of SAE couplings are standardization, high sealing, high pressure resistance and interchangeability, which ensure that equipment produced by different manufacturers can be reliably connected.
SAE couplings common type specification standard:
SAE J514 , scope of application: 37 ° flare hydraulic couplings, the main features: metal-to-metal sealing, high pressure resistance.
SAE J1926, Scope of application: O-ring sealed fittings, main features: repeatable disassembly, anti-leakage.
SAE J2044, Scope of application: hydraulic quick-change couplings, main features: quick connect/disconnect, anti-drip leakage.
SAE J518, Scope of application: flanged hydraulic fittings, main features: for ultra-high pressure systems.
SAE J560, scope of application: automotive electrical connectors, main features: waterproof and dustproof, standardized plugs.

Frequently Asked Questions (FAQ)
What is the difference between SAE fittings and NPT fittings?
SAE fittings usually use O-ring or 37° flare sealing, while NPT (American Standard Taper Pipe Thread) relies on thread sealing and is prone to leakage.
How much pressure can SAE quick-change couplings withstand?
– About 3,000~5,000 psi for regular models and up to 10,000 psi for high pressure models (e.g. SAE J2044).
Can SAE fittings replace ISO fittings?
– No, you need to use an adapter (e.g. SAE to DIN).
