PFS

The polyurethane seal type Aston Seals PFS has been developed to assure a SAE !ange sealing and to substitute traditional O-Rings when they are not suitable due to di"cult conditions such as high pressure or rough surface finish. The pro#le is inspired by a semicompact rod seal type SD which has demonstrated great efficacy and versatility. A flush fitting with the outside diameter reduces the radial movements induced by the frequent “pumping” phenomenon of pressure. 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.
