The rod seal type Aston Seals XL, mainly suitable for low pressure conditions or pneumatic  eld, is composed of:

• A dynamic seal element which assures exceptional low friction and high speed performance, as well as high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomers.
• A standard size O-Ring with low permanent deformation as energizing component on the static side
• Low static and dynamic friction, also without lubrication
• No tendency of stick-slip
• Space-saving construction and simple groove design
• Good resistance against extrusion
• High compatibility with nearly all fluids (with the right choice of O-Ring material)
• High speed allowed
• High temperature resistance
