The Hunger Ice Wiper type A-EIS is used in applications
where standard elastomer wipers wear too quickly
as a result of contaminants adhering to the piston rod.
The wiper comprises a metal housing with an integral
brass scraper and NBR wiper ring. The brass scraper
has radial clearance in the housing.
The brass scraper removes any stubborn dirt from the
rod, leaving the secondary NBR wiper to remove smaller
loose particles of dust, water, etc..
