PRODUCTS DETAILS

Description-BD Two-way Sealing

The Piston Set OK profile is a bi-directional piston seal designed for heavy-duty hydraulic applications. Its durable, two-piece design installs easily onto a solid piston without the necessity of auxiliary tools. When installed into the bore, the diameter of the OK profile is compressed to close the step cut in the cap to provide excellently, drift-free sealing performance.

Property

Application Range
  Pressure[MPa] Temperature [℃] Sliding speed[m/s] Medium
