Description
The MERKEL PT1 double wiper consists of a PTFE profile ring with a sealing edge and a wiper edge and two O-rings as the elastic preloading elements. The profile ring is manufactured from the MERKEL special compound MT28 (PTFE/ bronze) which is characte- rised by particularly good pressure and abrasion resistance. The double wiper can be combined with NBR or FPM O-rings to suit the medium and temperature. The sealing edge formed on the PTFE profile ring in the direction of the pressure space reliably wipes off any adhering residual oil film on the out stroke of the piston rod. The residual oil volume is transported back into the pressure space during the return stroke when a seal with good return capability (e.g. OMS-MR) is used.
