Piston seal 90x79x4.2 GER

GER piston seals have designs in 2 parts consisting of special compound PTFE ring and O-ring used as pressure ring. This de suitable up to a pressure of 400 bar in double acting cylinders. The advantages compared with other sealing systems are line velocity reaching at 5 m/s, non-stick slip feature in long static use, low friction endurance, durability against high temperatur big variety of chemical liquids, providing piston as one part and small. By using O-ring, used as pressure ring, in different combinations it is possible to solve all sorts of problems. Technical Data Pressure: 400 bar Temperature: with NBR O-ring: -35 to +105 with FKM O-ring: -35 to +200 Speed: 5m/s Media: Hydraulic oils (mineral oil-based) Material Material: Almost all media O-ring: NBR/FKM Color: Green/Brown O-ring: Black/Brown Advantages High static and dynamic sealing effect Low friction, high efficiency Stick-slip free starting, no sticking Easy installation
