SEAL KITS

Seals for Telescopic Cylinders – EDBRO, HYVA, BINOTTO

Sealing systems for telescopic hydraulic cylinders are designed to ensure leak-free operation, smooth extension and retraction of multiple stages, and reliable performance under high-pressure conditions. These cylinders are widely used in tipping systems, dump trucks, and heavy-duty hydraulic applications.

We offer a complete range of replacement and OEM-compatible seals for EDBRO, HYVA, and BINOTTO telescopic cylinders. The seals are designed to meet or exceed the original specifications, ensuring compatibility, durability, and efficient performance in demanding working environments.

Sealing Components Typically Include:

• Piston seals – ensure pressure separation between stages

• Rod/gland seals – prevent external leakage around the rod

• Wipers (scrapers) – protect the internal system from dirt and debris

• Guide rings – stabilize moving parts and reduce metal-to-metal contact

• Back-up rings & O-rings – support sealing elements and improve pressure resistance

Materials Used:

• Polyurethane (PU): Excellent wear and extrusion resistance

• NBR (Nitrile Rubber): Good oil and hydraulic fluid compatibility

• PTFE (Teflon): Low friction and high-temperature stability

• Fabric-reinforced rubber (FKM/NBR): For heavy-duty applications

Each seal is manufactured to withstand:

• High operating pressures (up to 300+ bar)

• Wide temperature ranges

• Contaminated working conditions (dust, mud, moisture)
