description

O-ring rubber seal is static sealing part for hydraulic, fuel and lubrication flanges, connectors and valve blocks. It seals the gap by compression deformation to retain fluid and block dirt and muddy water. Aging, cracking, extrusion damage and permanent compression set will lead to leakage, unstable pressure and hydraulic system contamination.

FAQ 

Q：Can I keep using the O-ring if it seeps slightly?
A：Not recommended. The rubber has lost compression, leakage will get worse and dirt may enter the hydraulic system.

Q：Can I reuse the intact O-ring after removal?
A：No. Permanent compression deformation occurs, re-installation leads to poor sealing.

Q：Can ordinary grease be used for lubrication during assembly?
A：Use compatible grease only. Incompatible grease will cause rubber swelling and premature failure.

Q：What causes O-ring extrusion damage?
A：Overpressure, excessive clearance, lack of groove chamfer and twisting during assembly are common causes.
