ConvaTec Sur-Fit Natura Convex Insert for use with 45mm Skin Barriers, Fits 35mm Stomas

ConvaTec Sur-Fit Natura Convex Insert for 45mm Skin Barriers, Fits 35mm Stomas

The ConvaTec Sur-Fit Natura Convex Insert is a simple, effective accessory that adds convexity to a standard flat Sur-Fit Natura skin barrier. Designed to snap into the 45mm flange/ring, this insert helps a flush, recessed, or retracted stoma protrude more effectively so output drops cleanly into the pouch instead of undermining the seal. It's ideal for anyone who loves the reliability of their existing Sur-Fit Natura two-piece system but needs a little extra convexity for confident, leak-resistant wear.

Once snapped into the flange, the insert applies gentle, even pressure around the stoma opening, encouraging the stoma to project into the pouch and helping to flatten peristomal creases. This can dramatically improve wear time and skin protection for challenging stoma profiles, all without switching to an entirely new barrier. Because it works within the standard Sur-Fit Natura coupling, you keep the familiar snap-fit connection you already trust. ConvaTec uses a helpful color-matching system to make selection easy—this insert is green and is built to pair with a 45mm skin barrier and a 35mm (1-3/8 inch) stoma opening.

This insert is sized specifically to fit a 45mm flange with a 1-3/8 inch (35mm) stoma opening and is sold as a box of 5. It is not made with natural rubber latex and, like other ostomy supplies, is FSA/HSA eligible. Select your option below to add it to your Sur-Fit Natura routine.
