The Aston Seals AR is a seal with asymmetric lips designed for light and medium duty applications where spaces and friction need to be low.
It can be used either as a single acting seal or, in presence of fast and high pressure variations, in tandem configuration as a “secondary” seal behind a PTFE one.
It is used in the same housing normally destined to PTFE seal of which has similar dimensional characteristics but, compared to it, better sealing capabilities, greater easy installation and lower cost.
The seal is made of a polyurethane compound that ensures excellent properties on wear-resistance, extended service life and resistance against extrusion.

• Good sealing performance
• Low cost solution
• Easy installation
• Designed to snap fit into its housing
• Simple groove design and space-saving construction
• Excellent wear-resistance
• Extended service life
• Good temperature resistance
