SAE fittings are hydraulic hose connectors that comply with SAE (Society of Automotive Engineers) standards and are suitable for use in high-pressure hydraulic systems and hydraulic transmission systems. Our SAE fittings offer high strength, wear resistance, and corrosion resistance, and can withstand pressures up to 5000 psi. They are widely used in hydraulic systems to connect hoses, pipes, and equipment, ensuring sealing and reliable transmission under high pressure.
SAE fittings can be categorized into flared SAE hydraulic fittings, O-ring face seal (ORFS) SAE hydraulic fittings, SAE flange hydraulic fittings, and SAE ORB hydraulic fittings.
As a supplier of hydraulic fittings, we manufacture a wide range of SAE fittings in large volumes, offering custom production in either carbon steel or stainless steel, as well as hydraulic hose assemblies. Our minimum order quantity is 500 units, with better pricing available for larger orders.
We also offer custom manufacturing services, allowing us to adjust the size, materials, and style to meet your specific needs. Simply send us an inquiry, and our team will create a hydraulic solution tailored to your requirements.
Types of SAE Fittings
SAE O-ring seal fittings utilize the compression deformation of elastic O-rings to achieve a leak-free seal, possessing extremely strong leak-proof performance. They are widely used in industrial and engineering machinery pipelines subjected to high pressure, high vibration, and strong pulses.

Features of SAE fittings
SAE fittings
Various seal types: Depending on the application, these primarily include 37° flare seals (JIC; metal-to-metal line contact), O-ring face seals (ORFS; flat-face compression of an O-ring, offering superior leak resistance), and O-ring flat-face flange seals (Code 61/62; flange faces clamped by bolts), accommodating requirements ranging from low pressure to ultra-high pressure (up to 6000 PSI/414 bar).
Wide range of applications: Covering hydraulic systems from low pressure to ultra-high pressure. Depending on the type, these fittings can generally withstand operating pressures from 350 bar to over 6000 psi.
Easy installation: The rationally designed structure allows for easy assembly, disassembly, and maintenance.
Standardization and Interoperability: Dimensions and construction strictly adhere to SAE standards, ensuring high interchangeability across brands and a mature supply chain; they are interchangeable with products from major brands such as Parker and Gates.
Excellent vibration resistance: Specifically, ORFS and flange-style fittings utilize a flat-face compression and O-ring design; compared to traditional threaded seals, they effectively resist loosening and leakage caused by high-frequency vibration and pressure pulses.
Applications of SAE Fittings
Construction Machinery: Hydraulic circuit connections for excavators, loaders, and cranes.
Agricultural Machinery: Hydraulic transmission and control systems for tractors and harvesters.
Industrial Hydraulic Equipment: Hydraulic presses, injection molding machines, and metallurgical machinery.
Oil & Gas & Energy: High-pressure hydraulic systems for oil drilling equipment and offshore platforms.
Automotive & Aerospace: Key hydraulic control components such as brakes, steering, and landing gear.
How to Choose SAE Fittings?
When selecting SAE fittings, first determine the required standard and type. SAE fittings include various styles, such as JIC 37° cone (SAE J514), O-ring face seal (SAE J1453), flanged (SAE J518), and pipe threaded (SAE J512). Different fitting types are suitable for different pressure ranges and operating conditions. For example, JIC fittings are commonly used in medium- and high-pressure hydraulic systems, while ORFS fittings are more suitable for vibration resistance and zero leakage requirements. Flange fittings are often used for large-diameter, high-flow pipes.
Operating pressure is a key factor in determining fitting selection. Generally speaking, pipe thread fittings are suitable for low-pressure systems, while JIC fittings are commonly used in medium- and high-pressure hydraulic systems. ORFS fittings are a more reliable option for high-pressure, vibration-resistant systems or where extremely tight sealing is required. For high-pressure and high-flow systems, flange fittings are more suitable.
In terms of fittings material, carbon steel fittings are the most widely used and suitable for general hydraulic systems. Stainless steel fittings are more corrosion-resistant and are commonly used in the marine, chemical, or food industries; brass fittings are more common in low-pressure or pneumatic systems. The sealing method should also be considered: JICs are metal-to-metal seals suitable for high pressures but require high installation precision; ORFS and flanges rely on O-ring seals, effectively resisting vibration and achieving zero leakage.
Finally, it is important to confirm that the fitting size and thread size are compatible with the system. SAE fittings are typically designated by dash size (e.g., -04, -06, -08) and differentiate between UNF and UN threads. If the system uses BSP or NPT threads, adapter fittings will be required. Overall, when selecting SAE fittings, consider the standard type, operating pressure, sealing method, material, size, and application environment to ensure safe and reliable operation of the hydraulic system.
