🛠 The Engineering Advantage

  • Maximum Strength with One-Piece Forging: Unlike multi-piece or welded elbows, our monolithic forged body provides a continuous grain structure through the bend. This eliminates weak points and offers the highest possible resistance to the pressure spikes and mechanical stresses common in hydraulic systems.
  • Optimized for Compact Layouts: The 90° design allows for immediate directional changes, enabling cleaner, tighter tube routing in crowded spaces like hydraulic power units and mobile equipment engine bays.
  • Proven, Standardized Design: By adhering to the globally recognized DIN 2353 / ISO 8434-1standard, our elbows guarantee dimensional interchangeability and performance you can trust for both new system builds and MRO replacements.
  • Molybdenum Disulfide Coated Nuts: To combat galling in high-torque hydraulic applications, all nuts are coated with Molybdenum Disulfide (Moly), a high-pressure solid lubricant that ensures smooth assembly and allows for reliable reassembly.

📌 Targeted Application Support

  • Hydraulic Power Units (HPUs): Ideal for routing lines from pumps and valves within the HPU frame.
  • Mobile & Heavy Equipment: Provides robust, vibration-resistant 90° turns for hydraulic lines on excavators, tractors, and mining equipment.
  • Shipbuilding & Offshore: Creates compact, corrosion-resistant pipe runs in tight engine rooms and on deck machinery.
  • Industrial Machinery: Connects hydraulic cylinders and motors where space is limited.



Frequently Asked Questions (FAQ)

Q1: Why is a one-piece forged elbow better for hydraulic systems?
A one-piece forged body is significantly stronger than an elbow made by welding two pieces together. The continuous grain structure of a forging provides superior resistance to the high-pressure pulses (hydraulic shock) and constant vibration that can cause welds to fail over time.
Q2: What is the difference between the L series and S series for elbows?
The "L" (Light) and "S" (Heavy) series correspond to different pressure ratings as defined by the DIN 2353 standard. The S serieshas a more robust, heavy-wall construction for higher pressuresystems (up to 630 bar), while the L seriesis more compact and designed for medium-pressure applications (up to 315 bar).
Q3: Does a 90° elbow affect the flow rate?
Yes, any bend in a system will create some pressure drop. However, our elbows are designed with a smooth, full-flow internal bore to minimize turbulence and keep pressure loss to a minimum, ensuring your system operates efficiently.
Q4: Are your DIN 2353 elbows interchangeable with Parker EO® or Voss®?
Our fittings are manufactured to be dimensionally compliant with the DIN 2353 / ISO 8434-1standard, making them interchangeable with other brands that also adhere to this standard, such as the Parker Ermeto (EO/EO-2) series. While Swagelok also offers some DIN-compliant products, their primary offering is double ferrule, so careful verification is needed. For critical applications, we always recommend using a consistent set of Stark components.
