Yes, cold-drawn seamless precision steel tubes are an excellent choice for hydraulic systems, especially in high-pressure, high-precision applications. Our production focuses on premium-grade tubes compliant with DIN 2391, EN 10305-1, and EN 10305-4, ensuring superior performance in demanding hydraulic environments.
✔ High Pressure Resistance – Our cold-drawn seamless tubes (e.g., ST52, E355) maintain structural integrity even under extreme hydraulic pressures.
✔ Tight Dimensional Tolerances – Standards like DIN 2391 ensure consistent inner diameters (ID) and smooth surfaces, minimizing turbulence and pressure drops.
✔ Superior Surface Finish – Hydraulic systems require smooth internal surfaces to prevent contamination; our tubes meet Ra ≤ 0.8 µm (or better upon request).
✔ Corrosion Resistance – We offer zinc-phosphated, galvanized, or stainless steel options for harsh environments.
✔ High Strength-to-Weight Ratio – Cold-drawn tubes provide better mechanical properties than hot-finished pipes.

When designing hydraulic systems, choosing the right fittings is crucial. Our precision tubes work best with tube fittings, but let’s compare them with hose fittings:
Feature | Tube Fittings (for DIN/EN Precision Tubes) | Hose Fittings |
Connection Type | Compression, flare, or bite-type (e.g., DIN 2353, ISO 8434-1) | Barbed, clamped, or threaded |
Pressure Handling | High pressure (up to 1000+ bar with proper fittings) | Lower pressure (typically < 350 bar) |
Vibration Resistance | More rigid, less prone to leaks | Flexible but may loosen over time |
Precision Alignment | Perfect for machined hydraulic blocks | Less precise due to hose flexibility |
Best Used With | Our DIN 2391 / EN 10305 tubes | Rubber or thermoplastic hoses |
Key Takeaway: For high-pressure, leak-free hydraulic systems, precision steel tubes with compression fittings are the best choice.
The surface finish of hydraulic tubing is critical for efficiency and longevity. Our precision tubes meet strict standards:
✅ Cold-Drawn Seamless (CDS) – Smooth internal surface (Ra ≤ 0.8 µm) for reduced friction.
✅ Phosphated (Zinc-Phosphate Coating) – Enhances corrosion resistance and improves oil retention.
✅ Honned / Skived & Rolled – Ultra-smooth finish (Ra ≤ 0.4 µm) for high-performance hydraulics.
✅ Galvanized (Optional) – For outdoor or corrosive environments.
DIN 2391 – Defines precision seamless tubes for mechanical & hydraulic applications.
EN 10305-1 (E235, E355) – Cold-drawn seamless tubes for precision engineering.
EN 10305-4 (St52, St37.4) – Tubes with special tolerances for hydraulic systems.
✔ Compliant with DIN 2391, EN 10305-1, EN 10305-4 for guaranteed quality.
✔ Superior surface finishes for optimal hydraulic performance.
✔ Compatible with high-pressure tube fittings (DIN 2353, ISO 8434).
✔ Custom sizes & coatings available (zinc, phosphate, honing).
For hydraulic systems requiring reliability, precision, and durability, our cold-drawn seamless steel tubes are the optimal solution.
