Ensure superior, leak-proof connections for your metric hydraulic systems with our precision-engineered Stainless Steel Flareless Tube Fittings. Designed for direct tube-to-tube connection, these high-performance fittings adhere to the rigorous DIN 2353 and ISO 8434-1 standards, guaranteeing global interchangeability and reliability. The innovative flareless (bite-type) design eliminates the need for tube flaring, providing a robust, permanent grip that withstands high pressure and vibration. Machined from corrosion-resistant AISI 316/316L stainless steel, they are the ideal choice for demanding applications in chemical processing, marine, offshore, and industrial machinery where safety and durability are paramount.
Zero-Leak, High-Pressure Seal: The precision 24° cone sealing system creates a metal-to-metal seal between the fitting body and the nut, ensuring a leak-free connection resistant to pressure surges and vibration.
Secure Flareless Grip: The hardened cutting ring (bite ring) uniformly bites into the tube as the nut is tightened, forming a permanent mechanical hold without compromising the tube's integrity. This flareless compression method provides exceptional pull-out resistance.
Full Standard Compliance: Manufactured to exact DIN 2353 / ISO 8434-1 specifications, ensuring perfect compatibility with all metric tubing and ports designed to this global standard.
Superior Material & Finish: Made from AISI 316/316L stainless steel, offering excellent corrosion resistance in harsh environments. A passivated finish provides added protection against oxidation and contamination.
Easy, Tool-Free Assembly: No special flaring tools are required. Assembly is simple, clean, and fast, reducing installation time and labor costs while ensuring a consistent, reliable connection every time.
| Parameter | Specification / Description | |
|---|---|---|
| Design Standard | DIN 2353 | ISO 8434-1 |
| Connection Type | Flareless Bite-Type (Compression Fitting) for Tube-to-Tube and Tube-to-Port connections. | |
| Sealing Method | 24° Cone Seal (Metal-to-Metal contact at the cone seat). | |
| Gripping Method | Hardened steel Cutting Ring (Bite Ring) that grips the tube. | |
| Thread Type | Metric parallel threads according to standard. | |
| Primary Material | AISI 316 / 316L Stainless Steel (304 available on request). | |
| Pressure Rating | Light Series (L): Up to 250 bar (3,600 psi). Heavy Series (S): Up to 630 bar (9,100 psi). | |
| Temperature Range | -20°C to +100°C (standard). Up to +150°C with high-temperature seal materials. | |
| Tube Compatibility | Metric Seamless Steel Tubes and Stainless Steel Tubes (e.g., 6mm, 8mm, 10mm, 12mm, etc.). | |
| Seal Material (Cone) | Standard: Steel on Steel. Optional seals available for specific media. | |
| Configuration | Straight Connectors, Elbows (90°, 45°), Tees, Crosses, Bulkhead Unions, etc. |
These fittings are essential for creating reliable, high-pressure lines in systems requiring pure metric connections:
Industrial Hydraulics: Power units, machine tools, presses, and plastic injection molding machines.
Mobile Equipment: Hydraulic systems in European-engineered construction, agricultural, and forestry machinery.
Process Engineering: Chemical, petrochemical, pharmaceutical, and oil & gas instrumentation lines.
Marine & Offshore: Hydraulic systems on decks and engines where corrosion resistance is critical.
General Industry: Any application requiring a robust, maintenance-free connection for metric tubing.
To ensure a correct and leak-proof system, please specify the following when ordering:
Fitting Type & Configuration: (e.g., Straight Connector, 90° Elbow, Tee).
Tube Outer Diameter (OD): The exact metric diameter of your tubing (e.g., 10 mm).
Series: Light Series (L) for standard duty or Heavy Series (S) for high-pressure applications.
Material: 316 Stainless Steel (standard) or alternative.
⚠️ Critical Installation Note: Ensure the tube is cut squarely and deburred. Hand-tighten the nut until the tube cannot rotate, then tighten with a wrench for the specified number of turns (usually 1.25 to 1.5 turns) until a visible "bite" is achieved. Do not overtighten.
