Application and properties
Apply to the hydraulic cylinder of piston sealing, generally used in conjunction with the guide sleeve. The seal ring and piston conforming to be a symmetric section to achieve the sealing performance. The Non-standard Y-ring has the function of sealing and provides the elastic force to the sealing ring and compensates for the abrasion. Very high pressure stability under pressure and harsh conditions, high wear resistance, low friction, no crawling phenomenon.
Sealing ring: filled PTFE
Y-Ring: NBR / PU
