Piston Rod Seal - China

Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.

The 0-ring has a preloading effect, making the groove embedding more stable, and can be applied to higher pressures and allow larger extrusion gaps, high Under low pressure conditions, the sealing effect is equally significant.

Rod seal, single function, embedded groove stability, special structural design; high pressure resistance, allows larger extrusion clearance.
