Movement and impurities? I work out with a wiper

The wipers play a very important role in the hydraulic and pneumatic systems as they have the function of preventing foreign bodies such as dust, sand or metal shavings from penetrating inside the piston, preventing the possible damage to gaskets and surfaces of the system itself.

 

 
 

For each piston its wiper

SET R06

The R06 wipers have an internal diameter with a profile that prevents pressure build-up in the rear part, to prevent ejection from the seat. The profile offers low friction, excellent degree of scraping, ability to absorb external stresses, easy assembly. The R06 wipers are suitable for a semi-closed seat and are produced in NBR 90 Shore A.

SET R07

The R07 wipers have an internal metal insert which guarantees adequate rigidity to prevent their expulsion. The profile offers low friction, excellent degree of scraping, ability to absorb external stresses, easy assembly. The R07 wipers are suitable for an open seat, they are produced in NBR 90 Shore A.

SET R08

The R08 wipers have a (single) lip with a step on the external diameter in order to obtain a greater anchorage on the seat bottom diameter. The profile offers low friction, excellent degree of scraping, ability to absorb external stresses, easy assembly. The R08 wipers are suitable for a semi-closed seat, they are produced in NBR 90 Shore A.

SET R09

The R09 wipers have a vulcanized external metal cage, in order to prevent the expulsion of the same. The profile offers low friction, excellent degree of scraping, ability to absorb external stresses, easy assembly. The R09 wipers are suitable for an open seat, they are produced in NBR 90 Shore A.
