A42 Wiper
A42
Wiper with a less than 45° sharply-defined lip edge. Made from Polyurethane AU 92. The A42 is a single function wiper. It is pressed against the descending piston rod wiping the dirt from the surface of the rod. The seals, their associated elements and the medium are protected from dirt. The high wear-resistance of the polyurethane provides this wiper with a particularly long service life. Pads on the inner diameter support the correct functional fit and prevent additional pressure build-up in the back area which could press the wiper out of its housing.
Application:
Hydraulic and pneumatic systems, reciprocal movements, medium to heavy dirt load.
Operating Conditions:
Working Temperature: -40°C to 100°C (-40°F to 212°F)
Speed: = 2 m/s
