Product Description

A customized hydraulic oil seal rubber O-ring is a specialized sealing component designed to meet specific requirements in hydraulic systems. These O-rings prevent fluid leakage, withstand high pressures, and resist wear, chemicals, and extreme temperatures.

 Material Options:

• NBR (Nitrile Rubber) - Good oil/fuel resistance, cost-effective.

• FKM (Viton) - High heat/chemical resistance, ideal for harsh conditions.

• EPDM - Excellent for water, steam, and some chemicals.

• Silicone (VMQ) - Flexible, good for wide temperature ranges.

• HNBR - Enhanced durability for high-pressure applications.

 Customization Options:

• Size (ID, OD, Cross-Section) - Tailored to fit your hydraulic cylinder/piston.

• Hardness (Shore A) - Adjustable for compression and sealing efficiency.

• Temperature & Pressure Ratings - Designed for specific operating conditions.

• Special Coatings - PTFE or other treatments for reduced friction.

• Colors & Markings - For easy identification in assembly.

 Applications:

• Hydraulic cylinders, pumps, valves, and actuators.

• Heavy machinery (construction, agriculture, mining).

• Automotive and aerospace hydraulic systems.

• Industrial equipment requiring leak-proof seals.
