☑️ In the automotive industry, O-rings serve as critical sealing components, and material selection directly impacts performance. Common options include nitrile rubber (NBR), fluorocarbon (FKM), and ethylene propylene diene monomer (EPDM), each with unique properties tailored to specific automotive

What are X-Rings?X-Rings (also known as four-lip seals or Quad-Rings) are a rubber seal with a special cross-section. Its cross-section is "X" shaped, which is different from the circular cross-section of the traditional "O-ring". It is an upgraded version of the O-ring, with better sealing performa

What is TB Rubber Oil Seal?TB Rubber Oil Seal is a high-performance rotary shaft seal with a double-lip structure, which is widely used to prevent lubricating oil leakage and external impurities such as dust, sand, and water vapor from invading bearings or machinery. It is a commonly used oil seal s

Polyurethane Oil Seal is a sealing element made of polyurethane elastomer (PU) material. It is widely used in hydraulic systems, pneumatic devices and heavy-load mechanical equipment, playing a key role in preventing oil leakage and external contaminants from entering the system. Material advantag
