The flange size ensures a secure and leak-proof connection between the pouch and skin barrier in two-piece systems. Choosing the correct flange size, like the 2(3/4)" flange in Convatec 401577 SUR-FIT Natura or the Convatec 421642, is vital for comfort and preventing leakage. Flange sizes vary to accommodate different stoma sizes and user preferences, so a range of sizes is available to ensure the best fit for each individual.
