High Anti-rust Grade SAE British DIN Stainless Adapters and Fittings
Premium hydraulic connectors designed for exceptional performance and longevity in high-temperature (up to 550°F) and high-pressure (up to 10,000 PSI) settings are stainless steel adapters and fittings. These fittings, which are made of 316/304 stainless steel, have unparalleled corrosion resistance, which makes them perfect for industrial systems, marine applications, and abrasive fluids. They guarantee leak-proof connections across crucial hydraulic and pneumatic systems and come in a variety of thread standards (BSP, NPT, JIC, SAE, and Metric) and configurations (straight, elbow, tee, and cross).
Description
1. Material & Grades
316 Stainless Steel: Superior corrosion resistance against saltwater, chemicals, and acids (ideal for marine/oil/gas).
304 Stainless Steel: Cost-effective for general industrial use with moderate chemical exposure.
Optional Grades: 321 (high-temp), 17-4PH (high-strength) for specialized needs.
2. Thread Types & Sizes
Global Compatibility: BSP (British), NPT (American), JIC (37° flare), SAE, Metric threads.
Size Range: 1/8 inch to 2 inches, covering most hydraulic and pneumatic requirements.
3. Pressure & Temperature Ratings
Adapters: 3,000–10,000 PSI (size-dependent).
Hose Fittings: Up to 5,000 PSI for dynamic applications.
Temperature Range: -50°F to 550°F, suitable for cryogenic to high-heat fluids.
4. Configurations
Straight, 45°/90° Elbow: Flexible routing in tight spaces.
Tee, Cross, Bulkhead: For complex system layouts.

Key Advantages
✔ Unmatched Durability: 3–5x longer lifespan than carbon steel in corrosive environments.
✔ Safety: No rust/debris contamination in sensitive systems (e.g., food, pharma).
✔ Low Maintenance: No plating or galvanizing needed.
✔ Global Standards: Meets SAE, DIN, ISO, and ASTM specifications.
Application
✔ Oil & Gas: Offshore rigs, pipelines (resists H2S/sour gas).
✔ Chemical Processing: Acid/alkali fluid transfer.
✔ Marine: Saltwater cooling, ballast systems.
✔ Food/Beverage: 316L for sanitary fittings.
✔ Pharmaceutical: Non-reactive, sterilizable surfaces.
