EXCLUDER M/2 OR is a two piece single acting wiper which consists of one special designed PTFE profile ring and o-rings as energizing element. wiper ensures that foreign particles are not introduced into the hydraulic systems , avoiding wear and damage to all the internal components including seals
•Mobile hydraulics , aluminium injection machines and industrial machinery , control and regulation equipment
We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
EXCLUDER M/2 ORINGS wipers have to be used with GIR or TESCO rod seals to prevent hydrodynamic pressure build up. If that is not possible some precautions have to be taken to prevent hydrodynamic pressure between wiper and seal (see section: Hydraulic Sealing Elements- Sample Designs). At high temperature working conditions FPM energizing O-ring and special mixture PTFE ring are able to be manufactured according to customer's request.
