wedi S-Dry Mixing Valve
wedi S-DRY Mixing Valve Collar - Waterproof Valve Seal for Shower Systems
The wedi S-DRY Mixing Valve Collar is a purpose-built waterproofing accessory that seals around the shower’s mixing valve—one of the most common leak-risk penetrations behind tile. It bonds into the membrane layer to help block moisture migration behind wall tile.
Features
-
Seals a critical penetration point: Helps protect the wall assembly by sealing around the mixing valve opening where water can otherwise get behind tile.
-
Flexible collar design: Prefabricated “flexi collar” style for quicker, more consistent installs than field-cut patches.
-
Fits common valve openings (and can be modified): Listed as Ø 3-15/16 in. and wedi notes it may be modified by cutting the fleece to open the diameter for larger valves (avoid cutting the top half).
-
Simple thinset install: Applied with cement-based tile adhesive (thinset) and pressed flat to remove air pockets; seams in wet areas are treated with a joint sealant to prevent water migration behind tape.
-
Packaged individually: Handy for ordering exactly what you need per valve.
