Sealing ring: filled with modified thermoplastic material
Expansion ring: Nitrile rubber NBR
2. Application scope
DT type piston seals are mainly used in heavy-duty hydraulic equipment and are particularly suitable for double acting pistons. These types of seals are suitable for working pressures up to 50MPa, and can be even higher in some cases.
Please refer to Parker's OK series standards when designing and selecting.
3. Features and advantages
3.1. Resistance to impact load;
3.2. Small shape;
3.3. High wear resistance;
3.4. Suitable for grooves according to the international standard ISO 7425-1;
3.5. Due to the special material properties of the hydraulic cylinder sealing ring, it has strong anti extrusion ability under high pressure and large gaps;
3.6. Even after holding the pressure for a long time, the friction between starting and moving is very low;
Due to the open structure of the hydraulic cylinder sealing ring, it is easy to install on the integral piston without the need for auxiliary tools.
