Rancilio Composite Paper Heating Element Gasket This paper-composite gasket is the forgiving option for heating element service on older or slightly warped boiler surfaces, where a PTFE gasket might not seal reliably. It's discontinued by Rancilio, but remains far more compression-forgiving than PTFE on questionable surfaces, the tradeoff is that it can be tough to remove once compressed for a long stretch. SPECIFICATIONS 63 x 48 x 2 mm COMPATIBILITY Fits: Rancilio heating element mounting flange INSTALLATION Straightforward DIY task during element replacement, though budget extra time for gasket removal if the machine hasn't been serviced in years. PRO TIPS If the old gasket won't budge, don't force it with metal tools against the boiler face, soak it or use a plastic scraper to avoid scratching the sealing surface.
