Does your seal become gooey and mushy?

Are you getting leaks or red sore skin under your flange? 

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

Siltac® Silicone 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.

Siltac is quick and easy to apply; simply stretch the silicone seal around your stoma and Siltac will return to its natural shape to provide a snug and comfortable fit.


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