Flange seals and static sealsThe following procedure describes how to fit flange seals and static seals.ActionCheck the flange surfaces. They must be even and free from pores.1It is easy to check flatness using a gauge on the fastened joint (without sealing com-pound).If the flange surfaces are defective, the parts may not be used because leakage couldoccur.Clean the surfaces properly in accordance with the recommendations of ABB.2Distribute the sealing compound evenly over the surface, preferably with a brush.3Tighten the screws evenly when fastening the flange joint.4O-ringsThe following procedure describes how to fit o-rings.NoteActionEnsure that the correct o-ring size is used.1Defective o-rings, including damagedor deformed o-rings, may not be used.Check the o-ring for surface defects, burrs,shape accuracy, or deformation.2Defective o-rings may not be used.Check the o-ring grooves.3The grooves must be geometrically correct andshould be free of pores and contamination.Lubricate the o-ring with grease.4Tighten the screws evenly while assembling.5Make sure that no grease is left on the robotsurface.150 Product manual - IRB 7603HAC039838-001 Revision: M© Copyright 2011-2018 ABB.
