Ensure superior performance and longevity in your hydraulic systems with our premium Stainless Steel Hydraulic Hose Fittings. Engineered for the most challenging environments, these fittings provide robust, corrosion-resistant connections between hoses and system ports. Manufactured from high-grade AISI 304, 316, and 316L stainless steel, they excel in industries like marine hydraulics, chemical processing, food and beverage, and high-pressure washdown where resistance to rust, chemicals, and extreme temperatures is critical.
Our comprehensive range complies with the international ISO 12151 series of standards, guaranteeing interchangeability, reliable sealing, and safe operation under high pressure. Available in reusable (re-attachable) and permanent crimp styles, they are compatible with various hose types, including spiral wire, braided, and thermoplastic hoses.
The ISO 12151 standards specify the dimensions, performance requirements, and testing for hose fittings with different end connections. Each part of the standard corresponds to a specific port connection type defined in the ISO 8434 series. This ensures a perfect, leak-proof interface between the hose assembly and the equipment.
| ISO 12151 Standard Part | Corresponding Port Standard (ISO 8434) | Connection Type & Key Features |
|---|---|---|
| ISO 12151-1 | ISO 8434-3 | O-Ring Face Seal (ORFS). Features a flat face with a groove for an O-ring. Provides an excellent, leak-free static seal ideal for high-pressure and high-vibration applications. |
| ISO 12151-2 | ISO 8434-1 | 24° Cone with O-Ring (DKO/ Metric Cone). A common metric style where sealing is achieved by an O-ring compressed on a 24° cone seat. |
| ISO 12151-3 | ISO 6162 | SAE 4-Bolt Flange. Used for high-pressure, high-flow applications (e.g., Code 61 for 3000 PSI, Code 62 for 6000 PSI). Provides a very secure connection. |
| ISO 12151-4 | ISO 6149 | Metric Stud Ends (with O-Ring). Features a straight metric thread and seals with an O-ring against a flat surface, common in European machinery. |
| ISO 12151-5 | ISO 8434-2 | 37° Flared (JIC). A globally popular style that seals via metal-to-metal contact of two precision 37° flare seats. |
| ISO 12151-6 | ISO 8434-6 | 60° Cone (BSPP). A British standard parallel thread fitting that seals with a 60° cone and often an O-ring or copper washer. |
Material & Testing: All fittings are manufactured from stainless steel to resist corrosion and pitting. They are designed to pass stringent performance tests for impulse, pressure, and burst as required by the standards.
The tables below provide key specifications and example dimensions for popular fitting types. Our range covers sizes from small instrumentation to large industrial flows.

| Primary Materials | AISI 304, 316, 316L Stainless Steel |
| Pressure Rating | Varies by style; typically up to 6,000 PSI for high-performance fittings like flanges. |
| Temperature Range | Compatible with standard hydraulic fluids from -40°F to +250°F (-40°C to +121°C), subject to seal material. |
| Seal Options | Standard Buna-N (NBR). Viton (FKM), EPDM, and others available for specific fluid/ temperature compatibility. |
2. Example Dimensions: 37° Flare (JIC) Male Swivel Elbow (90°) – per ISO 12151-5
| Hose Dash Size | Thread Size (Male JIC) | Dimension A (Length) | Dimension B (Centerline Height) | Wrench Flat (AF) |
|---|---|---|---|---|
| -06 | 3/8"-24 | 1.97" (50 mm) | 1.26" (32 mm) | 0.94" (24 mm) |
| -08 | 1/2"-20 | 2.20" (56 mm) | 1.38" (35 mm) | 1.10" (28 mm) |
| -10 | 5/8"-18 | 2.44" (62 mm) | 1.50" (38 mm) | 1.26" (32 mm) |
| -12 | 3/4"-16 | 2.68" (68 mm) | 1.57" (40 mm) | 1.38" (35 mm) |
3. Example Dimensions: ORFS (O-Ring Face Seal) Straight Plug – per ISO 12151-1
| Hose Dash Size | ORFS Thread Size | O-Ring I.D. | Hex Size | Overall Length |
|---|---|---|---|---|
| -06 | 3/8" | 0.75" (19.1 mm) | 0.88" (22.4 mm) | 1.50" (38.1 mm) |
| -08 | 1/2" | 0.88" (22.4 mm) | 1.06" (26.9 mm) | 1.69" (42.9 mm) |
| -10 | 5/8" | 1.06" (26.9 mm) | 1.25" (31.8 mm) | 1.88" (47.8 mm) |
| -12 | 3/4" | 1.19" (30.2 mm) | 1.38" (35.1 mm) | 2.00" (50.8 mm) |
Unmatched Durability: Stainless steel construction ensures exceptional resistance to corrosion, weathering, and many chemicals, leading to a longer service life than carbon steel, especially outdoors or in washdown environments.
Guaranteed Compatibility & Safety: Adherence to ISO 12151/8434 standards guarantees correct mating with equipment ports, preventing leaks and system failures. They are designed to meet or exceed performance requirements for impulse fatigue and burst pressure.
Superior Seal Integrity: Whether using the O-Ring Face Seal (ORFS) for zero-leakage or the 37° flare (JIC) for robust metal-to-metal contact, our fittings provide reliable seals that withstand vibration and pressure spikes.
Wide Application Range: Suitable for a vast array of media—including hydraulic oil, water, fuel, and certain chemicals—across industries like mobile equipment, shipbuilding, energy, and manufacturing.
Proper assembly is critical. Ensure hose ends are cut squarely and cleanly. For permanent fittings, use the correct crimping die specified by the fitting manufacturer. For reusable fittings, follow the recommended assembly torque. Always match the fitting thread and sealing type (JIC, ORFS, BSPP, etc.) exactly to the equipment port.
