🛠 The Engineering Advantage

Maximum Integrity with One-Piece Forging: Unlike fabricated tees, our monolithic forged body provides a continuous grain structure, eliminating welds and joints. This offers the highest possible resistance to the combined stresses of system pressure and vibration at the critical junction point.

Balanced Flow Path for System Stability: The internal passages are precision-machined to ensure smooth, balanced flow distribution between the run and branch ports, minimizing turbulence and maintaining consistent pressure in your hydraulic circuit.

Proven, Standardized Design: By adhering to the globally recognized DIN 2353 / ISO 8434-1standard, our tees 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). This high-pressure solid lubricant ensures smooth assembly and allows for reliable reassembly.

❓ Frequently Asked Questions (FAQ)

Q1: Why is a one-piece forged body so important for a tee fitting?

A tee is a high-stress point in a hydraulic system. A one-piece forged body is significantly stronger and more resistant to fatigue than a tee made by welding pieces together. This eliminates welds as potential failure points, greatly enhancing the long-term safety and reliability of your system.

Q2: What is the difference between a Union Tee and a Branch Tee?

A Union Tee(this product) connects three tube lines together. A Branch Tee connects two tube lines (the "run") and has a threaded port (the "branch") for connecting an instrument or a different type of fitting. Choose the tee that matches your connection requirements.

Q3: Can I use this tee to connect tubes of different sizes?

Our standard Union Tee connects three tubes of the same size. However, we offer Reducing Union Tees that allow you to connect tubes of different diameters. Please contact our engineering team for available size combinations.

Q4: Are your DIN 2353 tees interchangeable with Parker EO® or Voss®?

Our fittings are manufactured to be dimensionally compliant with the DIN 2353 / ISO 8434-1 standard, making them interchangeable with other brands that also adhere to this standard, such as the Parker Ermeto (EO/EO-2) series. For critical applications, we always recommend using a consistent set of Stark components for guaranteed performance.
