K98 Hydraulic rod seals

K98 is a single acting hydraulic sealing element consisting of a specially formed polyurethane u-ring and an elastomer o-ring. It is designed to be used in systems where pressure changes and shock pressures occur, in operations with vibration, in applications with long-term locked applications.

Advantages

Superior static and dynamic sealing effect
Design providing good sealing performance at shock, low and variable pressures
Safely operating with the elastomer o-ring in long duration locking systems
High wear resistance

Area of Application

Mining industry
Iron and steel industry
Scrap metal presses
Mobile machinery
Marine hydraulics
