TPM Combination Seal for Hydraulic Cylinder Piston

The TPM seal assembly is a compact hydraulic piston seal consisting of one elastic sealing ring + two backup rings + two bearing rings. It provides double-acting sealing and guidance integration, suitable for working pressures up to 40MPa and temperatures from -30°C to +120°C. The seal is commonly used in mining hydraulic supports, industrial hydraulic cylinders, and heavy machinery applications.

1. Hydraulic Systems – Used in cylinders, pumps, and valves to prevent fluid leakage and withstand high pressure.  

2. Pneumatic Systems – Ensures airtight sealing in compressors and pneumatic actuators.  

3. Automotive Industry – Applied in shock absorbers, steering systems, and fuel systems for durability and chemical resistance.  

4. Industrial Machinery – Protects rotating shafts and bearings in heavy equipment from contaminants.  

5. Medical Devices – Used in fluid-handling systems due to biocompatibility and sterilization resistance.  

6. Marine & Offshore – Resists saltwater corrosion in ship components and underwater equipment.  

7. Food & Beverage Processing – Complies with FDA standards for seals in hygienic environments.  

8. Renewable Energy – Seals wind turbine hydraulic systems and solar panel components.
