Frequently Asked Questions

Are your seal kits compatible with international cylinder brands?
Yes. Our seal kits are designed using industry-standard profiles and dimensions. We utilize high-grade materials that are technical equivalents to brands like NOK, Hallite, and Trelleborg, ensuring 100% compatibility for repair and OEM services.
What materials do you offer for high-temperature hydraulic seals?
For extreme heat applications (up to 200°C), we provide specialized Viton (FKM) and PTFE-based sealing systems. For standard industrial use, we offer high-tensile NBR and Polyurethane with excellent abrasion resistance.
How do your hydraulic valves ensure circuit safety and stability?
Each of our valves—whether relief, counterbalance, or check—is precision-machined and undergoes individual pressure-test calibration. This ensures immediate response and zero-leakage holding performance in your hydraulic system.
Can you provide custom-sized seal rings for older cylinder models?
Absolutely. If standard sizes don't fit your older equipment, we can manufacture custom seals and guide rings based on your measurements or physical samples with rapid lead times.
What is the expected service life of your hydraulic seals in high-cycle use?
Our seals are engineered for millions of cycles. By utilizing high-fatigue-resistant polymers and precision-molded lips, we minimize friction and wear, significantly extending the maintenance intervals of your cylinders.
Do your components come with material and quality certification?
Yes. Every shipment of valves and seals includes a quality certificate. We maintain full traceability of our material batches to ensure consistent performance across all global industrial applications.
