ConvaTec SUR-FIT Natura Moldable Durahesive Skin Barrier System | Convex & Flat Variants
The ConvaTec SUR-FIT Natura Moldable Durahesive Skin Barrier system is a two-piece ostomy base platform designed to provide a secure, customized seal across multiple stoma types and output conditions.
This system includes convex, flat, hydrocolloid collar, and acrylic collar variants engineered to match different leakage risks, stoma profiles, and wear-time requirements.
KEY FEATURES
- Durahesive hydrocolloid for extended wear protection
- Moldable and cut-to-fit options depending on SKU variant
- Convex options for recessed or flush stomas
- Flat options for standard stoma profiles
- Hydrocolloid or acrylic tape collar for edge stability
- Supports SUR-FIT Natura two-piece coupling system
- Designed for liquid and semi-liquid output protection
SKU STRUCTURE (NORMALIZED SYSTEM VIEW)
Convex Hydrocolloid Tape Collar
- SKU 404592 — Small 1-3/4" flange
- SKU 404593 — Medium 1-3/4" flange
- SKU 404594 — 4-1/2" x 4-1/2" flange
Flat Hydrocolloid Collar
- SKU 411800 — Small 1-3/4"

Important: Each SKU represents a different mechanical seal profile. Selection must match stoma shape, output consistency, and flange size requirement.
WHEN TO USE EACH TYPE
- Convex: Recessed, flush, or retracting stomas needing outward pressure
- Flat: Standard protruding stomas with stable output control
- Moldable/Collar systems: When irregular shape requires adaptive sealing
- Acrylic collar: Higher stability adhesive interface for extended wear needs
FIT & SELECTION WARNING (HIGH IMPACT)
Incorrect barrier selection is the leading cause of leakage, skin irritation, and premature wafer failure in SUR-FIT systems.
Convex and flat systems are not interchangeable — they apply different mechanical forces to the stoma.
If you are unsure which SKU or flange size matches your stoma, we strongly recommend confirming before ordering.
FAQ (DECISION ENGINE — NOT GENERIC)
What is the difference between convex and flat SUR-FIT barriers?
Convex barriers apply outward pressure to support recessed or flush stomas, while flat barriers rely on surface sealing for protruding stomas.
When should I use moldable vs cut-to-fit?
Moldable systems conform directly to the stoma shape, while cut-to-fit requires pre-measurement and trimming before application.
Why are there multiple collar types?
Hydrocolloid collars provide flexibility and moisture response, while acrylic collars offer more rigid adhesion stability depending on wear conditions.
Can I mix different SUR-FIT SKUs?
No. The pouch and barrier must match within the SUR-FIT Natura coupling system and compatible flange size.
What causes early leakage in this system?
Most failures are caused by incorrect convex/flat selection, wrong flange size, or poor alignment during application rather than material failure.
NEED HELP SELECTING THE RIGHT SKU?
Choosing the correct SUR-FIT barrier type is critical for preventing leakage and protecting peri-stomal skin.
