Marlen All-Flexible Ostomy Mounting Rings & Urostomy Pouches

Marlen's All-Flexible line is built for people who want a secure, reusable ostomy system that conforms to the body's natural contours. Every piece in this collection — from the flat and convex mounting rings to the clear urostomy pouches — shares the same soft, pliable construction that made Marlen a longtime favorite among ostomates who prioritize a comfortable, watertight seal over disposable convenience.

The mounting rings are the foundation of the reusable system. Each measures 3-3/4 inches in outer diameter (oval styles run 3-3/4 x 2-3/4 inches) and comes in a range of stoma openings so you can match the ring precisely to your stoma size. Precutting to the right diameter matters: too large invites leakage and skin exposure, too small can pinch the stoma. Marlen offers openings from 3/4 inch through 1-3/8 inch, in both flat profiles for flush or protruding stomas and oval convex designs (GN-60) that apply gentle pressure around a retracted or flush stoma to help it protrude into the pouch.

You'll also find a material choice. Green neoprene rubber rings (GN-101, GN-50, GN-60) are durable and reusable, giving a firm yet flexible mount that holds up to repeated cleaning. White vinyl rings (WV-101-E, WV-101-B) offer a softer, latex-free alternative for wearers with rubber sensitivities.

For urostomy wearers, the Marlen All-Flexible Urostomy Pouches in Regular (MAF12114) and Large (MAF-12-114) sizes feature a clear film for easy stoma monitoring and a built-in anti-reflux valve design that keeps urine away from the skin. Pairing these pouches with the matching mounting rings creates a complete, low-profile appliance many find quieter and more discreet than one-piece disposables.

If you're new to the system, size your rings first from a measured stoma, then choose the pouch style that fits your output. This collection is part of our broader ostomy and urology offerings — browse All Products to find complementary skin barriers, adhesives, and accessories.
