The seal type Aston Seals UPN is the natural further development of the UP seal. It is a high performance all purpose lipseal suitable for both rod and piston which combines the advantage of a highly elastic rubber and the abrasion resistance of polyurethane. The UPN profile assures a good reaction against shock pressure peaks and low friction in all conditions.

The energizing O-Ring guarantees a good sealing performance in the low pressure range. The material used to produce this seal
is a polyurethane compound that ensures excellent properties on wear-resistance, extended service life and resistance against
extrusion.
