Purpose and performance Mainly used for sealing hydraulic cylinder pistons, this seal consists of two components: a high hardness open sealing ring made of special materials, and a rubber rectangular ring that can provide elasticity. Due to the open structure of the sealing ring, the problem of requiring special tools for installation of the grid ring has been solved. The installation space of the 0K seal is small and the groove is simple. Installation is simple and convenient, without the need for tools, can resist impact loads, has low friction resistance and no stickiness, and has excellent friction resistance. Working conditions Temperature range: -30~+110C Working speed: 1m/s Working pressure: 0-80Mpa Medium: petroleum based hydraulic oil, fire-resistant Hydraulic fluid, environmental protection and safety Hydraulic fluid (bio oil), water and others, depending on the sealing ring material Standard materials Sealing ring: filled with PTFE O-ring: NBR or FKM
