Pre-sized ostomy barriers in Canada — shop skin barriers with fixed stoma openings manufactured to exact specifications. Pre-sized barriers are designed for specific stoma dimensions and coupling sizes, offering a precise factory-engineered fit for established ostomy systems.
Who are pre-sized barriers for? Pre-sized barriers are typically used with specific 2-piece system configurations where the stoma opening and flange coupling are matched to a particular setup. They're common in ConvaTec Synergy and Stomahesive systems and select Hollister product lines. If you need more flexibility in stoma opening size, consider a cut-to-fit or pre-cut barrier instead.
What to look for: Match the exact stoma opening size and flange/coupling diameter to your current system. These barriers are designed for specific configurations, so confirming your model number and size from your current product packaging is essential before ordering.

Pre-Sized Barriers FAQ
What is a pre-sized ostomy barrier?
A pre-sized barrier has a fixed stoma opening that is manufactured to a specific dimension. Unlike cut-to-fit barriers, the opening cannot be adjusted. These barriers are designed for particular system configurations where the stoma size and flange coupling are precisely matched.
How is a pre-sized barrier different from pre-cut?
Both come with a fixed opening, but pre-sized barriers are typically part of specific system configurations (like ConvaTec Synergy or Stomahesive lines) where the stoma size, flange type, and coupling are all matched together. Pre-cut barriers are more broadly compatible and come in a wider range of individual stoma sizes.
How do I know if a pre-sized barrier will fit?
Check the product's stoma opening size and flange coupling diameter against your current system. The safest approach is to match the exact model number from your current product packaging. If you're unsure, consult your stoma care nurse before switching products.
What systems use pre-sized barriers?
Pre-sized barriers are commonly found in ConvaTec product lines including Synergy Stomahesive, Synergy Durahesive, and select Sur-Fit configurations, as well as certain Hollister CeraPlus products. Each system has its own coupling mechanism, so barriers are not interchangeable between brands.
How often should I change my ostomy barrier?
Most manufacturers recommend changing your barrier every 3 to 7 days, depending on the product and your individual situation. Signs it's time to change include lifting edges, itching or irritation under the barrier, or reduced adhesion. Always follow the manufacturer's instructions and your clinician's guidance.
