A102 single acting piston nutrings by ALP are designed with shorter outer sealing lip and intended only to be used in piston application of standard cylinders.
They are manufactured with 90 Shore NBR or 92 Shore PU compound as a standard.
A102 piston nutrings offer easy assembly even into closed housings, very economic sealing solution, simple groove design and superior dynamic and static sealing effect to the system.
This type of seals can be used safely in construction machinery, moving platforms, forklifts, agricultural machinery, as well as any other standard cylinders.
It is recommended to use A102 with at least one ALP guiding element, such as A251, A254, A255 or A256, depending on the working conditions.
