Product Description

High Pressure Hydraulic Sealing Rings HNBR/FKM for Cylinders & Pumps - OEM Available
Hydraulic seals prevent fluid leakage in cylinders/pumps, ensuring efficient system operation. Common types: piston seals, rod seals, O-rings (NBR/FKM/PTFE materials). Used in construction, agriculture, and industrial machinery.
Product Description
Hydraulic Sealing Rings 
Hydraulic Sealing Rings is the key Guardians in Hydraulic Systems, Hydraulic sealing rings play a vital role and are widely used in numerous industries such as construction machinery, automobile manufacturing, and aerospace. Behind the stable and efficient operation of hydraulic systems, hydraulic sealing rings are indispensable and act like loyal guardians, silently ensuring the sealing and reliability of the entire system.
Our Hydraulic Sealing Rings hot sales and common shapes include O-rings, U-rings, Y-rings, and so on. The O-ring, with its simple annular structure, is easy to install and has a good sealing effect, so it is widely used in many occasions.
Our Hydraulic sealing rings mostly use material including:Nitrile Rubber (NBR), Fluoroelastomer (FKM),Polyurethane (PU),Silicone Rubber, Ethylene Propylene Diene Monomer (EPDM).
Our Hydraulic sealing rings are very popular and buyers like to go with us with long term business because:
Our hydraulic sealing rings are designed with precision to ensure a perfect fit ,and Excellent Sealing Performance
We use top - grade materials to manufacture hydraulic sealing rings
Our hydraulic sealing rings have good compatibility with various hydraulic oils and lubricants
Our hydraulica sealing is of long service life and low maintenance requirements of the sealing rings also further reduce the overall cost of use for customers, bringing more economic benefits

Storage& Maintenance
1. Regular Inspection: Periodically check the O-ring for signs of wear, such as abrasion on the surface, and aging, which may present as cracking, hardening, or discoloration. 
2. Timely Replacement: Replace O-rings immediately if they are damaged, deformed, or show signs of aging. A defective O-ring can no longer ensure proper sealing performance.
3. Exposure Avoidance: Prevent O-rings from being exposed to harsh environments for extended periods.
