🛠 The Engineering Advantage

Superior Tube Grip for High Vibration: The case-hardened single ferruleis designed to progressively bite into the tube as the nut is tightened, creating an exceptional mechanical grip that resists the most demanding vibration and pressure pulses found in hydraulic systems.

Proven, Standardized Design: By adhering to the globally recognized DIN 2353 / ISO 8434-1standard, our unions guarantee dimensional interchangeability and performance you can trust for both new system builds and MRO replacements.

Forged Body for High-Pressure Integrity: Our unions are machined from one-piece forged 316/316L stainless steel, providing a superior grain structure that withstands high working pressures and hydraulic shocks without fatigue.

Molybdenum Disulfide Coated Nuts: To combat galling in high-torque hydraulic applications, all nuts are coated with Molybdenum Disulfide (Moly). This high-pressure solid lubricant ensures smooth assembly and allows for reliable reassembly.

❓ Frequently Asked Questions (FAQ)

Q1: What does "DIN 2353" mean?

DIN 2353 is a German industrial standard (now harmonized with ISO 8434-1) that specifies the design and dimensions for metric bite-type tube fittings. Compliance with this standard ensures that our fittings are dimensionally interchangeable with other DIN-compliant products and meet proven performance criteria.

Q2: What is the difference between the L series and the S series?

The "L" stands for Light (Leicht) series and "S" stands for Heavy (Schwer) series. The S series has a thicker, more robust construction and is designed for higher pressure applications, while the L series is more compact and used for medium-pressure systems. You must choose the series that matches your system's pressure requirements.

Q3: Can I use your single ferrule fittings with gas?

While our single ferrule fittings provide an excellent seal for hydraulic fluids, for critical gas or vacuum applications, we generally recommend our Double Ferrules series, which is specifically designed for maximum gas sealing integrity.

Q4: Are your single ferrule fittings interchangeable with other brands?

As long as the other brand is also manufactured in compliance with DIN 2353 / ISO 8434-1, our components (bodies, nuts, ferrules) are designed to be dimensionally interchangeable. However, for critical applications, we always recommend using a consistent set of Stark components for guaranteed performance.
