8mm Group Seal for E61 Groups

This 8mm Group Seal suits all E61 Groups. Made with durable rubber, this seal is designed to be positioned into your coffee machines group around the shower plate. Ideally group seals should be replaced every six months as the rubber will become brittle with consistent heating and cooling. If the rubber becomes brittle you may notice that your machine begins leaking around the portafilter and that the portafilter may become difficult to remove.
