ConvaTec SUR-FIT Natura Two-Piece Standard White Stomahesive Skin Barrier With Mold-To-Fit Opening
/
ConvaTec SUR-FIT Natura Durahesive Moldable Skin Barrier with Collar | Convex & Flat System
The ConvaTec SUR-FIT Natura Durahesive Moldable Skin Barrier with collar is a two-piece ostomy base designed for adaptive sealing and secure coupling within the SUR-FIT Natura system.
This barrier uses mold-to-fit technology to conform around the stoma, reducing the need for cutting while improving seal consistency across varied stoma shapes.
KEY FEATURES
- Durahesive hydrocolloid for liquid output protection
- Mold-to-fit opening reduces cutting and measurement errors
- Available in convex and flat configurations (SKU dependent)
- Collar system improves edge stability and wear performance
- Supports SUR-FIT Natura two-piece pouch coupling system
- Multiple flange sizes for pediatric to adult applications
SKU SYSTEM (FULL NORMALIZED MATRIX)
Convex Durahesive Moldable (Acrylic Tape Collar)
- SKU 404592 — 45mm flange — small stoma range
- SKU 404593 — 45mm flange — medium stoma range

Important: Durahesive is optimized for liquid output protection, while Stomahesive is generally used for more formed output conditions. Geometry (convex vs flat) must match stoma profile.
WHEN TO USE THIS SYSTEM
- Stoma shape is irregular or changes over time
- Need improved sealing without precise cutting
- Managing liquid or semi-liquid output
- Experiencing leakage with standard cut-to-fit systems
FIT & DECISION WARNING (CRITICAL)
Leakage in this system is most often caused by incorrect geometry selection (convex vs flat), not adhesive failure.
Convex is required for flush or retracted stomas to push the stoma outward. Flat is used when stoma protrusion already provides separation from skin.
Moldable technology reduces sizing errors but does not replace correct geometry selection.
If unsure, confirm before ordering.
FAQ (DECISION ENGINE — HIGH INTENT)
What is the main advantage of moldable barriers?
They reduce sizing errors by adapting directly to the stoma shape during application, improving seal consistency compared to manual cutting.
When should convex be used?
Convex is used when the stoma is flush or recessed and output is undermining the barrier seal.
What causes leaks in this system?
Most leaks result from incorrect convex/flat selection or improper molding technique, not product defect.
Does Durahesive work better for liquid output?
Yes. Durahesive is designed to resist breakdown from liquid output and provides a “turtlenecking” effect for added protection.
Can all SKUs be mixed with any SUR-FIT pouch?
No. All components must match SUR-FIT Natura coupling size and system compatibility.
NEED HELP SELECTING?
Correct barrier selection directly impacts wear time, leakage prevention, and skin protection outcomes.
