Our Flange Seal Rings are perfect for ostomates who want to stay active while feeling secure with their ostomy appliances. Flange Seal Rings are made of a thin, flexible, transparent and breathable adhesive acrylic. They go on top of your flange, creating a waterproof seal around it, allowing you to go swimming, shower, and be active without worrying about your ostomy appliances leaking or separating. Our Flange Seal Rings are available in two sizes: Small: suitable for 45mm to 57mm standard flanges. Medium: suitable for 57mm to 70mm standard flanges, and 45 to 70mm floating flanges
