Reasons for good sealing of rubber O-ring

The tightness of rubber O-ring has always been an important information in the market. Here is the reason for the good tightness of rubber O-ring.

Rubber O-ring has always been an important product in the domestic sealing equipment market, accounting for a large part of the domestic market share. Of course, this is inseparable from its own superior performance. The rubber O-ring generally used in pump and valve equipment has a simple structure, so the manufacturing process is simple, and the cost is greatly reduced. Therefore, it can better meet the installation and use requirements in practical application, and the disassembly is convenient. Therefore, coupled with good sealing ability, it has become a popular product in the sealing market.

The rubber O-ring is generally installed in the groove. If the design size is inaccurate and the size is out of tolerance, it is likely that the rubber O-ring surface and the groove contact surface are incomplete and the sealing effect is not the best, or the rubber O-ring is compressed too much and squeezed by individual stress at the edge of the groove, resulting in direct damage to the rubber O-ring, The sealing effect will be greatly reduced, and the use cost will also rise greatly. During the sealing work, the rubber O-ring is often in contact with the oil. If the anti-corrosion performance is poor, it is easy to be corroded by the oil, resulting in poor elastic performance, thus affecting the sealing effect. The greater the pressure of the liquid in the seal, the greater the deformation of the rubber O-ring, so the pressure on the sealing surface will increase gradually in the sealing process, so the sealing effect is more obvious, which is also an important reason why the rubber O-ring can play a good sealing effect.
