The Graphite 5 (GR905) Glass Seal is a 3mm self-adhesive high-temperature rope that seals the glass panel inside the door frame of your Hi-Flame Graphite 5. When this seal deteriorates, air bypasses the glass and interferes with airwash performance. This genuine spare part is easy to apply and restores a proper seal around the glass, keeping the panel clear and the airwash effective.
