The rubber seal is the most basic element in the sealing device, and plays a very important role in the contradiction between leakage and sealing.

O-ring materials include nitrile rubber (NBR), fluoro rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc.

O-ring material hardness is the most important index for evaluating sealing performance.

damage during installation, that is, scratches when the edges and corners of the spouse pass through the hole

O-shaped rubber ring is also called O-ring for short because its cross-sectional shape is circular.

O-rings should be stored in places that are not exposed to direct sunlight, humidity and air to prevent accelerated aging of the O-rings.
