In high-pressure hydraulic systems where leaks equate to downtime and safety risks, the connection is your first line of defense. Stainless Steel JIC (Joint Industry Council) Hydraulic Fittings are engineered to be that impervious barrier. Renowned for their robust metal-to-metal seal, these SAE J514 and ISO 8434-2 compliant fittings provide unmatched reliability in environments plagued by vibration, pressure spikes, and corrosive elements. By specifying our AISI 304 or 316 Stainless Steel JIC fittings, you invest in a solution that eliminates common failure points, offering superior corrosion resistance and long-term durability where carbon steel fittings would falter.
The legendary reliability of Stainless Steel JIC 37° Flare Fittings stems from their precise mechanical design. The connection is formed between the 37-degree angled surfaces of the fitting body and a pre-flared tube, secured by a sleeve and flare nut. This creates a strong, leak-free joint that performs consistently under extreme conditions, offering a clear high-pressure hydraulic connector solution to common leakage problems.
Key Engineering & Performance Benefits:
Proven Leak-Free Seal: The metal-to-metal contact of the 37° flare provides a vibration-resistant seal, ideal for systems operating up to 2500 PSI and beyond, effectively fixing hydraulic fitting leak concerns at the design stage.
Superior Material Integrity: Forged from AISI 304 (1.4401) or 316 (1.4571) Stainless Steel, our fittings resist corrosion from moisture, chemicals, and salt spray, making them essential for marine, chemical, and food processing applications.
Direct Standard Compliance: Manufactured to meet ISO 8434-2 and SAE J514 dimensional and performance standards, ensuring perfect interchangeability and system integrity.
Broad Compatibility & Range: Available in a complete range of sizes from 1/8" to 2" in both straight and 45° or 90° configurations, providing versatility for any tube or hose layout.
The combination of a reliable seal and stainless steel construction makes JIC fittings for marine hydraulics, construction equipment, and the chemical industry the definitive choice. They are indispensable in sectors where failure is not an option:
Mobile & Off-Highway Equipment: Withstanding constant shock and vibration in hydraulic fittings for construction equipment, agricultural machinery, and logging equipment.
Marine & Offshore: Providing critical corrosion resistance for saltwater environments in steering systems, winches, and deck machinery.
Chemical Processing & PLC Systems: Handling aggressive fluids and solvents in transfer lines, pump connections, and instrumentation.
Industrial Manufacturing: Ensuring uptime in high-cycle applications like metal forming presses, plastic injection molding machines, and automation systems.
Energy & Transportation: Used in fuel lines, lubrication systems, and ground support equipment where reliability is paramount.
For your selection and design convenience, below is the key specification reference for our core JIC Straight Fitting series. All products are manufactured from AISI 304/316 Stainless Steel and comply with ISO 8434-2 and SAE J514 standards.
| Nominal Size | Thread Specification (Male) | Tube OD (Applicable) | Suggested Working Pressure | Compliant Standards |

| 1/4" | 7/8"-14 UNF | 6 mm / 1/4" | Up to 3000 PSI | SAE J514, ISO 8434-2 |
| 3/8" | 1-1/16"-12 UNF | 10 mm / 3/8" | Up to 3000 PSI | SAE J514, ISO 8434-2 |
| 1/2" | 1-5/16"-12 UNF | 12 mm / 1/2" | Up to 2500 PSI | SAE J514, ISO 8434-2 |
| 3/4" | 1-5/8"-12 UNF | 18 mm / 3/4" | Up to 2500 PSI | SAE J514, ISO 8434-2 |
| 1" | 2-1/16"-12 UNF | 25 mm / 1" | Up to 2000 PSI | SAE J514, ISO 8434-2 |
| 1-1/2" | 2-1/2"-12 UNF | 38 mm / 1-1/2" | Up to 1500 PSI | SAE J514, ISO 8434-2 |
| 2" | 3"-12 UNF | 50 mm / 2" | Up to 1200 PSI | SAE J514, ISO 8434-2 |
Selection Guide:
Size Selection: Choose the corresponding nominal size based on your system's tube outer diameter. Ensuring the tube is cut squarely and flared correctly to a 37° angle is crucial for a perfect seal.
Pressure Consideration: The pressures in the table are suggested routine working pressures based on stainless steel material. For pulsating pressure or extreme temperature applications, please consult our engineers.
Thread Compatibility: The threads of JIC fittings are typically UNF (Unified Fine Thread). Adapters are required when connecting to SAE O-Ring boss ports or BSPP threaded interfaces.
Selecting the correct fitting is crucial for system safety and performance. For applications involving high vibration or alternating pressures, comparing JIC vs ORFS fittings can determine the best seal type for your needs. When looking to buy JIC hydraulic fittings, ensure your supplier provides full material certification and compliance statements. As a leading stainless steel JIC fitting supplier and manufacturer, we offer comprehensive technical support to help you specify the perfect component, ensuring optimal performance and safety from the start.
Choosing a fitting is more than a procurement decision—it's an engineering choice that impacts your entire system's lifecycle. Our Stainless Steel JIC Hydraulic Fittings deliver a proven, standards-based solution that minimizes downtime and maximizes safety. By opting for stainless steel, you secure a long-lasting alternative to carbon steel hydraulic fittings, significantly reducing maintenance costs and risks.
