1. V-shaped sealing ring is an elastic rubber sealing ring that acts axially and is used as a pressure free seal for rotating shafts. The sealing lip has good mobility and adaptability, can compensate for large tolerances and angle deviations, can prevent internal grease or oil from leaking out, and can also prevent external splashing or dust intrusion.

2. The O-ring is mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is only limited to low-speed rotary sealing devices. The V-shaped sealing ring is generally installed in a groove with a rectangular cross-section on the outer or inner circle to play a sealing role.

Y-shaped sealing rings are widely used in reciprocating sealing devices. In addition, there is a spring tension (spring energy storage) sealing ring, which adds a spring to the PTFE sealing material. There are O-ring springs, V-shaped springs, and U-shaped springs.

※ The sealing ring has excellent sealing performance and long working life. The working life of dynamic pressure sealing is 5-10 times higher than that of conventional rubber sealing products, up to tens of times. Under certain conditions, it can have the same lifespan as the sealing substrate.

※ The sealing ring has low friction resistance and equal dynamic and static friction, which is 1/2-1/4 of the friction force of the "0" shaped rubber ring. It can eliminate the "crawling" phenomenon of low speed and low pressure movement.

The sealing ring is highly wear-resistant and has automatic elastic compensation function after the sealing surface is worn.

The sealing ring has good self-lubricating performance and can be used as an oil-free lubrication seal.

The sealing ring has a simple structure and is easy to install.

※ Working pressure of sealing ring: 0-300MPa; Working speed: ≤ 15m/s; Working temperature: -55-250 ℃.

※ Suitable media for sealing rings: hydraulic oil, gas, water, mud, crude oil, emulsion, water ethylene glycol, acid, alkali, chemicals, etc.
