Rubber Oil Seal
Rubber oil seal is a mechanical sealing element used to seal oil or other liquids. It is usually composed of rubber and metal materials. It prevents the leakage of lubricating oil or other liquids and prevents external dust and impurities from entering the sealing elements of mechanical equipment. It has excellent elasticity, wear resistance, and oil resistance, and is widely used in automobiles, industrial equipment, household appliances, and other fields.
AOBO focuses on the production of various high-quality rubber oil seals, providing a variety of material options, including oil-resistant NBR nitrile rubber, high-temperature resistant FKM fluororubber, environmentally friendly and non-toxic silicone, aging-resistant EPDM terpolymer rubber, etc., to fully meet your different needs.

- Silicone rubber: It has excellent high and low-temperature resistance and is suitable for food-grade or medical-grade applications.
- Nitrile rubber (NBR): It has excellent oil resistance and provides long-lasting and stable sealing performance.
- Acrylic rubber (ACM): It is resistant to high temperatures and oils, especially suitable for the automotive industry, meeting your needs for high-performance materials.
- Ethylene propylene diene monomer (EPDM): It is resistant to aging and ozone, suitable for providing long-term protection for your outdoor equipment.
Structure of AOBO Rubber Oil Seal
The structural design of the AOBO rubber oil seal is scientific and reasonable, providing you with excellent sealing performance and durability.
AOBO Rubber oil seals are usually composed of the following parts:
- Sealing lip: As the part in direct contact with the shaft, the sealing lip is the core guarantee of the sealing effect of your equipment, ensuring that the medium does not leak.
- Metal skeleton: The built-in metal skeleton provides strong support for the oil seal, enhances the strength and stability of the overall structure, and makes your equipment more reliable.
- Spring: The spring is designed to increase the contact pressure between the sealing lip and the shaft, ensuring that the sealing lip fits tightly with the shaft, further improving the sealing effect, and providing you with lasting protection.
- Rubber body: The rubber body wraps the metal skeleton, giving the oil seal excellent elasticity and sealing performance, adapting to various complex working conditions and meeting your diverse needs.

AOBO provides rubber oil seals in a variety of specifications and materials to meet the special needs of your different industries.
