AV ROD SEAL
The Aston Seals AV is a single acting rod sealenergized by a V-shaped metal spring resistantto corrosion.
The asymmetric profile, with appropriatelydesigned dynamic lip, short and heavy,ensures a reduction of friction and a longoperating life.
The inside metal spring ensures a tight sealeven at low pressures.
The possibility of combining different
Features
High compatibility with nearly all fluids
Low friction, even in the absence oflubrication
High speed allowed
No tendency of stick-slip
Excellent sealing capability even at lowpressure
Good wear-resistanceHigh temperature resistanceExtended service life
