PDL Double Working Piston 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.
Product Description
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.
PDL is a double working piston seal for relatively low pressures fitting in an O-ring groove. The special shape gives it a very low friction and is therefore very suitable to replace an O-ring in a dynamic application. It is used in hydraulic systems as well in pneumatics. It can also be used in other fluids.
Max. Velocity is 5 m/s also depending on the material used and the medium it is working in.
