1 PT 1 MERKEL PT 1 Low Friction Wiper Low friction wiper consisting of one profile ring with a sealing edge and a wiper edge, as well as two O-Rings as pre-load components. A wiper for improvement of overall tightness, PT 1 is fitted preferably in combination with our rod seals. We recommend a bore hold for relieving pressure. No pressure release is needed for these seals with a good pump-back action. Where there is a combination of seals without sufficient pump-back capability a pressure-relieving hole is required.

Medium/Temperature85 NBR B247 support cylinders hydraulic jacks mining hydraulics hydraulic presses Single-acting elastomeric rod wiper with support components. NBR rod wiper which finds its main use with large diameters. very good seat in the outer diameter very good wiping action wiper can be used for a broad temperature range no anti-rotation in housing and no pressure build-up between seal and wiper

4 P 7 Wiper MERKEL P7 Wiper Single-acting rod wiper made from Polyurethane with integrated metal retainer. PUR wiper for axial-accessible housings. Medium/Temperature85 NBR B247 cranes Single-acting rod wiper made from Polyurethane with integrated metal retainer. PUR wiper for axial-accessible housings. firm seat in installations space(press fit) made from highly wear-resistant polyurethane no open ring gap (dirt pocket) outwards between rod and housing easy to manufacture housing no corrosion between housing and wiper retainer

7 PU 5 MERKEL PU 5 Wiper Rod wiper with additional static sealing lip and support components; sealing edge of wiping lip lightly chamfered. The PU 5 is a single-acting wiper, use even in standardized housings according to ISO 6195 Type A. Medium/Temperature95 AU V149 fork lift trucks HGV loading cranes mining hydraulics telescopic cylinders loading platforms support cylinders hydraulic jacks cranes Rod wiper with additional static sealing lip and support components; sealing edge of wiping lip lightly chamfered. Single-acting wiper, use even in standardized housings according to ISO 6195 Type A. additional static sealing lip prevents ingress of dirt and water spray wiper lip with lightly rounded sealing edge wipes dirt away safely and leaves a residual oil film on the retracting rod the support on the wiper heel prevents twisting in the groove as well as pressure build-up between wiper and seal

8 PU 11 MERKEL PU 11 Double Acting Wiper The PU 11 double acting wiper is designed for improvement of overall tightness and has dimensions even for standardized housings; according to ISO 6195 type C. The PU 11 is fitted preferably in combination with our rod seals OMS-MR. The doublelipped wiper can take pressures up to 1.6 MPa. The lightly rounded sealing edge wipes dirt away safely and leaves a residual oil film on the retracting rod. Tightness, working life and friction behavior of the entire system are affected positively. Medium/Temperature95 AU V149 Hydraulic oils HL, HLP-30 C/-22 F to +110 C/ fork lift trucks standard cylinders U-Cup with wiper lip (double-lipped wipers); sealing edge of wiper lip lightly chamfered. Double wiper for improvement of overall tightness; dimensions even for standardized housings according to ISO 6195 type C. PU 11 is fitted preferably in combination with our rod seals OMS-MR. The double-lipped wiper can take pressures up to 1.6 MPa. sealing lips directed inwards fulfill the U-packing function wiper lip with lightly rounded sealing edge wipes dirt away safely and leaves a residual oil film on the retracting rod tightness, working life and friction behavior of the entire system are affected positively
