RDT High-Pressure Rod 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
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.
RDT is a double working rod seal for high pressure applications in combination with large gaps. It has a limited positioning function. It is only used in hydraulic systems. It can also be used in other fluids. It is used on its own. It is not suitable for high velocity in combination with high frequency.
Max. Velocity is 15 m/s also depending on the material used and the medium it is working in. It can be used on metallic rod materials or on ceramic rod coatings when applying the right compounds. For High density rod materials such as Inconel and Duplex, please ask you AST representative for our possibilities.
