KZT is used in combination with piston seals and anti-wear rings. This product is used in combination with anti-wear and piston ring seals to prevent cylinder oil from mixing with foreign particles, resulting in seal damage and a long service life. The piston rod seal is used in combination with a metal bushing to prevent damage to the rod due to the impurity immersion function of the PTFE. It is used to move the piston and rod in the cylinder. It has good guiding effect and can absorb radial force at any time to prevent metal-metal contact in the cylinder and reduce friction. According to your specific requirements, KZT has many materials that can be used for the guide ring.

This product is used in combination with anti-wear and piston rings to prevent cylinder oil mixing. Foreign objects and damage to seals and long seals ervice life. Piston rod seals, used in combination with oil pressure to prevent oil storage pressure.
