Natura Durahesive Skin Barrier, with Malleable Convexity and Adhesive Acrylic Collar | CV-404593
Durahesive® Moldable Convex Barrier
The ConvaTec Natura® Durahesive® moldable convex skin barrier (manufacturer reference 404593) is a convex barrier from the two-piece Natura® system featuring a no-cut moldable opening: it is shaped directly by hand to fit the stoma without needing to be trimmed with scissors. It suits stomas ranging from 22mm to 32mm (7/8" to 1 1/4") in diameter. Made of Durahesive® material with a white acrylic tape collar, it attaches via click coupling to any compatible 45mm Natura® system pouch — such as the precut barriers ref. 413181 and 413182 from the same line. Sold in a box of 10.
Key Features
- Moldable technology (no cutting): shaped by hand to the exact contour of the stoma, no scissors needed, for stomas from 22mm to 32mm (7/8" to 1 1/4").
- Durahesive® Material: extended-wear hydrocolloid that swells on contact with liquid or pasty output to protect peristomal skin.
- White acrylic tape collar: soft, discreet under clothing.
- Secure click coupling: compatible with ConvaTec Natura® two-piece system pouches, 45mm size; allows the pouch to be changed without removing the barrier.
- Built-in convexity: gentle pressure around the stoma, useful for flat, retracted stomas or those located in a skin fold.

Indications for Use
This moldable convex barrier is intended for people living with an ileostomy, colostomy, or urostomy whose stoma is flat, retracted, or irregularly shaped, for whom a fixed-size precut opening does not fit well. The moldable technology allows the opening to be shaped by hand, without cutting, to fit non-circular stoma contours. Before using a convex product, it is recommended to consult a wound, ostomy, and continence nurse or healthcare professional to confirm that this type of barrier is suitable for your stoma and peristomal skin.
Frequently Asked Questions
What is ConvaTec reference 404593?
404593 is the reference number assigned by ConvaTec to the Natura Durahesive convex skin barrier with moldable technology, white acrylic tape collar, 45mm coupling size, for stomas from 22mm to 32mm, sold in a box of 10.
What is the difference between a moldable barrier and a precut barrier like ref. 413181 or 413182?
A precut barrier (ref. 413181, 413182) has a fixed round opening already cut to a precise size (25mm or 28mm). The moldable barrier (ref. 404593) is not precut: it is shaped directly by hand to fit the exact contour of the stoma, which works well for irregular or oval-shaped stomas, within a 22mm to 32mm range.
Is this barrier compatible with the same pouches as the precut Natura barriers?
Yes. All of these barriers share the same 45mm coupling size and are compatible with ConvaTec Natura® two-piece system pouches.
Is this product sold individually?
Yes. Stomo Médical offers this barrier individually (CV-404593-1) or in a box of 10 (CV-404593).
How long can I wear this barrier?
Wear time varies by individual and stoma output type. Follow the recommendations of your healthcare professional or ostomy nurse.
