• Over compression of rubber gaskets creates long -term leakage!
• How many contractors know the specific installation torque value for a flange gasket yet alone how to properly apply it?
• Fastener assembly loading can be controlled by using a torque spanner.
• Friction is controlled by lubrication.
EUSR approved training will show you how!
