Product Description

MPM is a professional manufacturer of hydraulic cylinders and critical sealing components with decades of experience. We deeply understand the decisive role that sealing systems play in the performance, efficiency, and service life of hydraulic equipment. Therefore, we are dedicated to designing, producing, and testing high-performance hydraulic cylinder seals to ensure your equipment performs excellently even under extreme pressure, temperature, and demanding conditions, free from leakage concerns.

Our sealing solutions are widely used in various fields such as construction machinery, mining equipment, agricultural machinery, marine and maritime applications, and press machinery.

Product Advantages & Features:

• Exceptional Performance: Resistant to high pressure (up to 720 MPa for dynamic seals), high and low temperatures, wear, and impact.

• Long Service Life: Extremely low friction coefficient and outstanding wear resistance significantly extend the maintenance intervals for both the seals and the cylinder.

• Diverse Materials: We offer a variety of materials including Polyurethane, NBR, FKM, and PTFE to suit different hydraulic fluid media and working environments.

• Customization Capability: We can provide fully customized sealing solutions based on your cylinder dimensions, operating conditions, and specific requirements.

• Quality Assurance: Every manufacturing step, from raw materials to the finished product, undergoes strict quality control to ensure consistent and reliable product quality.

Groove surface characteristics: When working pressure>40MPa: S max=H8/f8.
