One-way operating AUAS

                                                          Merkel Wiper AUAS

•   Single acting wiper for the protection of cylinders against ingress of dirt use in standardised housings, amongst others, according to ISO 6195 Type B

• As a preference, we recommend the use of the more modern type AUAS R.

             The wiper lip with a radius reliably wipes away dirt and simultaneously          leave a residual film of oil on the retracting rod; friction behaviour, tightness and service life of the whole system are further improved

One-way operating AUASOB

                                                     Merkel Wiper AUASOB

• Single acting wiper for the protection of cylinders against ingress of dirt, use in standardised housings according to ISO 6195 Type A

One-way operating AUPS

                                                     Merkel Wiper AUPS

• Single acting wiper for the protection of cylinders against ingress of dirt, especially also as protective component and sealing component for pivoting bearings, amongst others, in standardised housings according to ISO 6195 Type B
• Secure seating in the housing (press fitting), no rotation with the shaft on pivoting motion
• Regreasing of pivoting bearings possible without problems; lip opens at low overpressure; old grease can escape

• NBR dirt wiper that is primarily used for large diameters
• Good seating at the outside diameter
• Very good wiping action
• Wiper can be used for a wide temperature range
• No twisting in the housing and no pressure build-up between seal and wiper

Two-ways operating P 8

                                                 Merkel Double Wiper P 8

• The Merkel Double Wiper P 8 exerts inwards the wiping function of a U-ring, and a wiping action outwards against soiling
• Strong wiping action against dirt
• Very good sealing effect against residual film of oil on the extending rod
• Wear-resistant

Two-ways operating P 9

                                                 Merkel Double Wiper P 9

• The Merkel Double Wiper P 9 exerts inwards the wiping function of a U-ring, and a wiping action outwards against soiling

Two-ways operating PRW1

                                                        Merkel Double Wiper PRW1

• Double wiper for housings based on ISO 6195 Type A
• No pressure build-up between wiper and rod seal due to integrated pressure relief (patented)
• Improved sealing of overall system due to dynamic sealing lip with punched sealing edge
• Wiping lips has outstanding wiping action against dirt
• Static sealing lip for additional protection against ingress of dirt and water

Two-ways operating PT 1

                                                 Merkel Double Wiper PT 1

• Double wiper for improvement of total tightness. Merkel Double Wiper PT 1 is preferably fitted in combination with our rod seals Merkel Omegat OMS-MR, Merkel Compact Seal T 20 or Merkel U-Ring LF 300
• Low friction, free of stick-slip
• Excellent regulation and positioning in operation
• Material variants for short stroke and high frequency available on enquiry
• High reliability, can accept the full operating pressure for short periods
• We recommend a pressure relieving bore. With buffer seals with good deformation value, pressure relief is not necessary. In any case, on the combination of seals without sufficient deformation value, e.g. Merkel Compact Seals NI 300, KI 310 and KI 320 a prssure relieving bore is required

Two-ways operating PT 2

                                                    Merkel Double Wiper PT 2

• Excellent regulation and positioning in operation
• Low friction, free of stick-slip
• Material variants for short stroke and high frequency, available on enquiry
• Especially suitable for large diameters

• Wiper lip with lightly rounded sealing edge reliably wipes away dirt amd leaves a residual oil film on the retracting rod
• Tightness, service life and friction behaviour of the entire system are improved
• Merkel Double Wiper OU 11 is preferably fitted in combination with our rod seals Merkel Omegat OMS-MR. The double-lip wiper can take pressure up to 1.6 MPa. If higher pressures can build up we recommend a pressure relieving bore between
