There are a lot of blisters on the surface of rubber O-rings in the later stage of production, which not only greatly reduces the appearance of the product, but also affects the performance of the product. So what are the reasons for the bubbles? What are the solutions?

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.
