Seals
The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.
Description
Static sealing lip to prevent mud from outer edge to enter;
Dedusting effect is good, high resistance to wear;
Special dustproof lip to return the piston rod, rod surface with thin oil film;
The inside of the sealing lip is the same as the Y ring sealing function;
The wild all-weather conditions;

The piston seal is a two-way seal, used in conjunction with two piston guide rings, and has a two-way sealing effect.
The Y-ring is designed as a static seal for the cylinder, which can replace the traditional O-ring/retaining ring combination. Through its unique design and material, the allowable extrusion gap can reach 0.4mm at a pressure of 500bar.
Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.
