Valve Body: Service and Repair
REPLACEMENTNOTICE: When working with FIPG material, perform the following:
^ Using a razor blade and gasket scraper, remove all old FIPG material from the gasket surfaces.
^ Clean all components thoroughly to remove all foreign matter.
^ Clean both sealing surfaces with a non-residue solvent.
^ Apply FIPG material in a bead of approximately 1 mm (0.04 inch) on the sealing surface.
^ Reassemble parts within 10 minutes of applying FIPG material. Failing to do so will require the FIPG material to be removed and reapplied.
