Are there dips or uneven skin around your stoma which cause leaks?
Does your current ostomy seal leave gaps around your stoma?

Sound familiar? That’s why we’ve found an alternative to traditional hydrocolloid convex seals that is kinder to skin and we want everyone to know about it.

Silvex® Silicone Convex Ostomy Seals are made with Sil2™ Breathable Silicone Technology. Sil2™ supports the skin’s natural barrier function and allows the skin around your stoma to breathe and heal by protecting it from irritants.

Silvex® seals come with all the same benefits as our flat silicone seal, Siltac, but in a mild convex shaped seal.  Silvex is for ostomates with uneven skin, dips or a moat around their stoma. It helps to fill the dips and gaps while gently pushing the stoma out to create a spout, helping output into the bag. Silvex’s flexibility means it comfortably responds to the changing size and shape of your stoma throughout wear.


We recommend you find your stoma size and then size DOWN to ensure a snug and secure fit.
