Flange size is crucial when purchasing a stoma cap because it must match your ostomy system for a secure, leak-proof fit. The best flange size is the one that corresponds exactly to your existing barrier or wafer system. Common sizes include measurements like 1-3/4" (45 mm), ensuring a snug and comfortable seal. For example, the Convatec 401909 SUR-FIT Natura Disposable Flange Cap features a 1-3/4" (45 mm) flange size, making it suitable for users with that specific requirement. Many stoma caps are available in multiple flange sizes, ensuring you can find the perfect match for your system.
