Aston PFS Type

The polyurethane seal type Aston Seals PFS has been developed to assure a SAE flange sealing and to substitute traditional O-Rings when they are not suitable due to difficult conditions such as high pressure or rough surface finish.

The profile is inspired by a semi-compact 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.

• Perfect fluid control under “pumping” pressure also
• High resistance against extrusion
• Excellent wear-resistance
• Extended service life
• Absence of induced radial movements
• Good temperature resistance
• Easy installation without expensive auxiliaries
