DIN 2353 Stainless Steel Banjo Fittings, Flange Adapters & Reducers: Compact Solutions for Complex Hydraulic Circuits

Navigate tight spaces and simplify complex system designs with our precision-engineered DIN 2353 Stainless Steel Banjo Fittings and related components. These specialized fittings serve as crucial tube-to-port interfaces, utilizing the reliable flareless bite-type connection system defined by the DIN 2353 / ISO 8434-1 standards-4-7. The unique banjo (eyelet) design allows fluid to pass through a hollow bolt, enabling a 90° or straight connection in confined areas, reducing the need for bulky hose bends and saving valuable space-3-6. Flange adapters and reducers complement this system by providing robust transitions to flange-mounted equipment and managing changes in tube diameter within the metric circuit.

Manufactured from corrosion-resistant AISI 316/316L stainless steel, these components deliver superior durability and leak-free performance in demanding hydraulic applications across mobile machinery, industrial automation, and chemical processing systems.

Product Features & Advantages

  • Space-Optimized Design: The compact, flat banjo fitting body allows for installation in extremely tight spaces where traditional elbows or connectors cannot fit. The hollow bolt design facilitates fluid passage directly through the fastener-6.

  • Reliable, Leak-Free Connection: Utilizes the proven DIN 2353 system where a hardened cutting ring bites into the tube against a 24° cone in the fitting body, creating a robust metal-to-metal seal that withstands vibration and high pressure-4.

  • Enhanced System Versatility: Flange adapters provide a secure transition from metric tube to standard SAE or other flange interfaces, while reducers allow for efficient system scaling and connection between different tube diameters-1.

  • Superior Material Performance: Made from AISI 316 stainless steel, these fittings offer excellent resistance to corrosion from water, chemicals, and saline environments, ensuring long-term reliability and reducing maintenance needs-4-7.

  • High-Pressure Capability: Designed to handle demanding system pressures. Components are available in Light (L) and Heavy (S) series to match specific pressure requirements, with the S series rated for the most severe duty cycles-4-7.

Typical Applications

These fittings are essential in applications where space constraints, reliability, and corrosion resistance are paramount:

  • Mobile Hydraulics: Compact connections on excavators, agricultural machinery, and crane outriggers.

  • Industrial Machinery: Internal hydraulic circuits of machine tools, plastic injection molds, and press lines.

  • Valve & Manifold Connections: Providing a compact, leak-free port connection for hydraulic valves and blocks.

  • Marine & Offshore Equipment: Fluid lines in corrosive environments where 316 stainless steel is required.

Selection & Installation Notes

  1. Correct Identification: For banjo fittings, specify the tube outer diameter (Ød2), the thread size and type (e.g., Metric or BSPP), and the required pressure series (L or S)-2-5. For reducers, specify the input and output tube diameters-1.

  2. Proper Assembly: Ensure the tube end is cut squarely and deburred. Hand-tighten the nut until the tube cannot rotate, then use a wrench to complete the assembly, allowing the cutting ring to properly bite into the tube. Avoid over-tightening-4.

  3. Seal Compatibility: Verify that the standard Viton (FKM) seal is compatible with your system's hydraulic fluid and operating temperature. Consult our team for alternatives if needed-4.
