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

NBR (nitrile rubber) seals are one of the most widely used sealing materials. Due to their good oil resistance, wear resistance and economy, they are widely used in the automotive, hydraulic, pneumatic, machinery manufacturing and other industries. But even if they are all NBR materials, the selecti

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
