Note: If the Fluid Section is to be used with a Polyester/Vinylester resin system then a liberal coat
of Red Grease should be applied to the Piston Cups before installing on to the Piston Body. The
Piston Cups on an Epoxy or Urethane system should be clean and in good condition with no
lubricant or grease. If in doubt contact the material manufacturer for recommendations.
