Piston Seal NBR

Installation points of Piston Seals:

1. Make sure that the cylinder barrel has a lead-in chamfer; if not, please use a mounting sleeve.
2. Deburring and chamfering or rounding of sharp edges to cover the threaded end of the screw.
3. Remove machining residues like chips, impurities and other foreign particles, and clean all parts.
4. It will be easier to install the seals if they are oiled or greased. Compatibility between Seal materials and these lubricants must be observed.
Do not use greases with solid additives such as molybdenum disulfide or zinc sulfide.
5. Use installation tools without sharp edges

It is recommended to use the installation tool, if it is not possible to use the installation tool to complete the installation, be sure to observe the following points:

1. Use oil, water, or use a hot air blower to heat to 80 ℃ to 100 ℃ (about 8~10 minutes, so that it expands and softens, and then it will shrink by itself.
shrunk to original shape) is easier to install.
2. Using a tool without sharp edges, expand the Sealing ring.
3. Use a separate recovery tool to complete the leveling of the seal ring, or use a cylinder with an introduction chamfer to level the installation in an open groove. Installation in an open groove is very simple, and the installation sequence is the same as that of the seal. The configuration is the same. During installation, the seals should be flat, and no storage is allowed.
in twisting. During the final installation (before the piston is loaded into the cylinder), the elastomer- or spring-forced seal must be leveled and rounded to prevent the seal from being cut or bitten. This can also be achieved by using a cylinder barrel with a sufficient length of lead-in chamfer or by using a levelling sleeve.
