Engineer robust and reliable metric hydraulic circuits with our comprehensive range of Stainless Steel DIN Fittings. This product family provides a complete connection system for both rigid tubing (DIN Tube Fittings) and flexible hoses (DIN Hose Fittings), all engineered to precise international standards for guaranteed performance and interchangeability. Manufactured from corrosion-resistant AISI 316/316L stainless steel, these fittings are the professional choice for demanding applications in mobile machinery, marine hydraulics, chemical processing, and industrial automation where durability and leak-free operation are critical.
Our products are defined by two core ISO standards: ISO 8434-1 for the tube-side connection and ISO 12151 for the hose-side and port interface. This dual-standard compliance ensures every connection point in your system is secure, compatible, and built to last.
Complete Metric System Compatibility: Designed specifically for metric-dimensioned systems, with tube sizes measured by outer diameter (OD) and threads in metric pitches (e.g., M14x1.5), ensuring perfect fit and function in European and globally designed equipment.
Superior Flareless Bite-Type Grip: The core of the DIN tube fitting system is the 24° cone seal and hardened cutting ring (bite ring). This design creates a permanent, vibration-resistant mechanical grip on the tube without requiring flaring, offering exceptional pull-out resistance and a reliable metal-to-metal seal.
Unmatched Corrosion & Chemical Resistance: Fabricated from AISI 316/316L stainless steel, these fittings provide outstanding resistance to rust, pitting, and a wide range of chemicals, making them ideal for harsh environments where carbon steel would fail.
Standardized for Global Interchangeability: Adherence to ISO 8434-1 and ISO 12151 guarantees that our fittings are dimensionally identical to those from other major global manufacturers. This simplifies sourcing, maintenance, and system design.
Optimized Pressure Ratings: Available in three distinct pressure series—Light (L), Heavy (S), and sometimes Extra Light (LL)—allowing you to select the optimal fitting for your system's working pressure, from standard duty to ultra-high-pressure applications.
The strength of the DIN system lies in its standardization. The table below clarifies how the hose fitting standards (ISO 12151) interface with the tube end connection standards (ISO 8434), creating a seamless link between hose, fitting, and port.
| Hose Fitting Connection (ISO 12151 Part) | Corresponding Tube End / Port Standard | Common Name & Key Feature |
|---|---|---|
| ISO 12151-1 | ISO 8434-3 O-Ring Face Seal | ORFS (O-Ring Face Seal). Provides a superior static seal via a captive O-ring. |
| ISO 12151-2 | ISO 8434-1 24° Cone | DIN / Metric 24° Cone. The standard bite-type connection for metric tubes. |
| ISO 12151-4 | ISO 6149 Metric Stud Ends | Metric Stud with O-Ring. Common straight-thread port connection for metric systems. |
| ISO 12151-5 | ISO 8434-2 37° Flared | 37° Flare (JIC). A globally recognized metal-to-metal sealing flare. |
Core Design Standard: ISO 8434-1
This is the fundamental standard for metric flareless tube fittings. It specifies the dimensions, performance requirements, and testing for the 24° cone and cutting ring assembly used in straight connectors, elbows, tees, unions, and stud ends.
The tables below summarize the critical specifications and size ranges for our Stainless Steel DIN Hydraulic Fittings.
1. Pressure Series & General Specifications
| Parameter | Specification | |
|---|---|---|
| Governing Standards | ISO 8434-1 (Tube Fittings), ISO 12151 Series (Hose Fitting Ends) | |
| Connection Type | Flareless Bite-Type (Cutting Ring) per ISO 8434-1 | |
| Sealing Method | 24° Cone Seal (Metal-to-Metal) | |
| Pressure Series | Light (L): Up to 400 Bar | Heavy (S): Up to 630 Bar |
| Primary Material | AISI 316 / 316L Stainless Steel | |
| Temperature Range | -20°C to +100°C (standard), wider with special seals |
2. Key Dimension Reference Table (Example: DIN 2353 Light Series (L) Straight Fitting)
| Tube OD (mm) | Thread Size (Metric) | Wrench Size (SW) mm | Approx. Length (L1) mm |
|---|---|---|---|
| 6 | M10x1 | 13 | 28 |
| 8 | M12x1.5 | 17 | 32 |
| 10 | M14x1.5 | 19 | 36 |
| 12 | M16x1.5 | 22 | 40 |
| 15 | M20x1.5 | 27 | 47 |
Note: Dimensions are indicative. For Heavy Series (S), Elbows, Tees, and Hose Tail variants (e.g., with BSPP thread), specific dimension drawings are available.
Our Stainless Steel DIN Fittings are essential in industries that rely on robust, metric fluid power systems:
Mobile Hydraulics: Excavators, loaders, agricultural and forestry machinery.
Industrial Plant: Machine tools, presses, plastic injection molding machines, and automation lines.
Marine & Offshore: Hydraulic systems on decks, winches, and in engine rooms.
Energy & Engineering: Wind turbines, test rigs, and heavy engineering equipment.
Specify with Confidence: To order, specify the Tube Outer Diameter, the desired Pressure Series (L or S), the Fitting Type (e.g., 90° Elbow, Straight Connector), and the End Connection (e.g., M18x1.5 Male Thread, Hose Tail -12).
