Product Introduction

A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion. For example, they are widely used in hydraulic cylinders of excavators, bulldozers, cranes, and many other types of heavy equipment.

Hydraulic seals are used hydraulic in cylinders to seal the openings between various components in the hydraulic cylinder. Seals are either moulded or machined and are carefully designed using sophisticated simulation software. Products perform both dynamic and static sealing. The range includes piston, rod, buffer and wiper seals, as well as guide rings and O-rings.

O-rings are one of the most common sealing solutions. HAISUN supplies O-rings in a wide range of sizes and different materials, which make them appropriate for a wide variety of operating conditions and applications. They are easy to install and they enable a simple and cost-effective seal housing design.
