Schmalz DR-MOS SI Silicone Sealing Rings Review: Specs, Price and Applications
Schmalz DR-MOS SI sealing rings are made from special foam for sealing on structured surfaces where normal suction pads cannot seal, such as studded, rippled or rough surfaces.
They come in a range of diameters and heights, fit standard FGA (1.5 bellows) and FG (2.5 bellows) silicone pads and attach with silicone adhesive. They are supplied as accessories, not pre-mounted.

Bonding to existing silicone pads keeps the standard pad's fitting and bellows.
Integration and Selection
Choose ring size to match the pad, bond with silicone adhesive and test on the actual surface.
Replace rings as they wear.
