RX2 high-performance double working 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. 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.

RX2 is a double working rod seal with positioning function. This seal is able to separate 2 media like oil and gas. It is normally used in hydraulic accumulator systems. The special shape makes it impossible for medium to pass in a static and dynamic situation. It can also be used in other fluids when the wright compound is chosen. However it contains elements that might be changed with other compounds before you are able to apply it with other fluids. Please ask your AST representative for information.

Max. Velocity is 3 m/s also depending on the material used and the medium it is working in.
