GT4 double working rotary seal
Seals are particular exposed to pressure, friction and temperature. Our aim is to design and make seals or sealing systems that perform optimal for all these parameters. Following from these parameters is wear, extrusion etc. Our materials are low friction and wear resistant. When applying the right surface parameters in combination with seal type and materials, we are able to supply a very wear and extrusion resistant sealing system for almost all applications.
Below you can find an overview of sealing and bearing materials. Please select the suitable material for your application. When you have any difficulties with selection of a material, contact your AST representative.
Sealing surfaces are very much known for influencing the wear, extrusion and the leakage rate for a sealing system. When applying our sealing systems, please follow our specifications. You will find these specifications through the schedule below.
GT4 is a double working high pressure O-ring activated rotation piston seal. This seal is very good wear resistant because the compound choice. It can be used in high pressure applications. It is used for hydraulic applications only. The maximum velocity is depending on the pressure applied. The rule of thumb is to use it with a maximum PV value of 4 (MPa x m/s).
Max. Velocity is 3 m/s.
