Description The Sawyer Cleaning Coupling is Sawyer's latest water filtration adapter that will allow you to backwash your Sawyer Micro or Squeeze Filter with a plastic bottle. The Sawyer Cleaning Coupling offers an alternative way to clean your Sawyer filter. To clean your filter with the Cleaning Coupling, remove the push-pull cap from your filter, attach the Coupling, then screw the other side of the Coupling onto a bottle filled with clean, filtered water. Once attached, you can forcefully squeeze the bottle to backwash and clean your filter. It's a great tool in making a gravity filtering kit with Vectos, water bottles or other collapsible containers too. Suitable for: Sawyer Micro Squeeze Squeeze Water Filtration Systems. **NOTE** This coupling only works with 28mm threads. This will not work with a BeFree filter or our 42mm Vecto.
