The correct method of installing the hydraulic sealing ring is as follows:


1. Check the relevant surfaces of the piston, cylinder and installation guide sleeve to ensure that they are fully clean, burr-free and edgeless.

2. The installation tools shall be smooth, edgeless and sharp to ensure that the seals will not be damaged in any form during the installation process.

3. A small amount of grease can be put on the relevant surface of the seals and cylinder to facilitate installation, but the residual grease is not allowed between the rubber elastomer and the sliding seal ring, otherwise it will affect the sealing performance.

4. Whether vertical or horizontal installation should maintain the coaxiality of the piston and cylinder, too much eccentricity is likely to damage the seal.
