A127 double-acting heavy duty piston seals with Z-cut

Categories

A127 double acting piston seals are designed for heavy duty applications. They are easily assembled thanks to the their Z-cut sealing ring.

A127 are highly resistant to hydraulic shock loads during operation, and they show resistance to extrusion thanks to the their high performance special material.

A127 seals have very low friction forces, even at the first starting movement in idle hydraulic cylinders, in pressurized or nonpressurized environment.They have excellent static and dynamic sealing property.
