Propane o-rings is a circular rubber seal with a circular cross-section, which is mainly used to prevent the leakage of liquid and gas medium in mechanical parts under static conditions. In some cases. The O-ring can also be used as the dynamic sealing element of axial reciprocating motion and low-speed rotary motion. According to different conditions, different materials can be selected to adapt to it.

The propane o-rings with a large cross-section should be selected as much as possible when selecting O-ring. In the case of the same clearance, the volume of O-ring squeezed into the gap should be less than the maximum allowable value.

For different kinds of fixed seal or dynamic seal applications, propane o-rings provides designers with an effective and economical sealing element. The O-ring is a bidirectional sealing element. The initial compression in the radial or axial direction during installation gives the O-ring its own initial sealing ability. The total sealing force is composed of the sealing force generated by the system pressure and the initial sealing force, which increases with the increase of the system pressure. O-ring in the static sealing situation shows a prominent role. However, O-rings are often used in dynamic applications, but they are limited by the speed and pressure at the seal.
