Features of Piston Rod Seals
1. The piston rod seal is a combined seal, which is prestressed by the O-ring to compensate for the initial state and work.
2. The seal is filled with additives such as graphite, copper powder, and carbon fiber, which can effectively reduce frictional resistance and improve wear resistance.
3. Since the piston rod seal is used in combination, it can avoid contact between metals, significantly improve the supporting capacity, and withstand certain lateral forces.
Piston rod seals are mainly made of polytetrafluoroethylene-based materials or polyurethane materials. Specifically designed for hydrodynamic applications, these materials offer excellent abrasion resistance and excellent extrusion resistance. Compatible with virtually all media, rod seals are unrivaled in extreme temperature conditions.
