Description
Description
The Scraper A5 is a one-piece rod scraper designed with two wiping lips to remove contamination and residual oil films from piston rods. Available in NBR, FKM or polyurethane (TPU), the A5 is offered for a range of hydraulic and pneumatic environments. NBR is suitable for general hydraulic and pneumatic use, FKM provides enhanced chemical resistance, and TPU is intended for mobile hydraulics exposed to heavy contamination. The secondary sealing lip improves removal of residual oil and the additional step on the outer diameter ensures a tighter fit and improved wiping action. Material hardness ranges from 90 to 95 Shore A, depending on the selected material.
Fields of application
