ConvaTec Sur-Fit Natura Convex Insert for use with 45mm Skin Barriers, Fits 32mm Stomas

ConvaTec Sur-Fit Natura Convex Insert for 45mm Skin Barriers

The ConvaTec Sur-Fit Natura Convex Insert is a smart accessory that adds convexity to your standard flat Sur-Fit Natura skin barrier. Designed to snap into a 45mm flange/ring, this insert applies gentle pressure around the stoma to help flush, recessed, or retracted stomas protrude more effectively. It's an ideal solution for anyone who needs the flush-promoting benefits of convexity without switching to an entirely new pre-shaped convex barrier.

Once seated inside your 45mm skin barrier, the insert creates a slightly protruding, dome-like profile that helps direct output down into the pouch and away from the peristomal skin. This improved seal reduces the risk of leaks and undermining, promotes a more secure fit, and can extend your comfortable wear time. Because it works with the barriers you already use, the insert lets you customize your Sur-Fit Natura two-piece system to match your body's unique needs. This model has a 1¼ inch (32mm) opening and is part of ConvaTec's color-matching system for a reliable fit—this size is green.

This convex insert is sold in a Box of 5 and is designed specifically for 45mm Sur-Fit Natura skin barriers to fit a 32mm stoma. Like all ConvaTec ostomy products offered here, it is not made with natural rubber latex and is FSA/HSA eligible. Confirm your barrier size and stoma measurement, then select your option below to order.
