The Sawyer Cleaning Coupling offers an alternative way to clean your Sawyer Squeeze filter or dual threaded MINI filter using a standard plastic bottle.

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.

Great tool in making a gravity filtering kit with Vectos, water bottles or other collapsible containers. 

NOTE: This coupling only works with 28mm threads. This will not work with a BeFree filter or our 42mm Vecto.


Filter Material: Plastic
Compatible: 28mm Vecto containers, Sawyer Squeeze Filter models (inc. Dual Threaded MINI)
Weight: ~0.2 oz

28 mm Sawyer Coupling

The 28 mm Sawyer Coupling has several uses, I use it to back flush my Sawyer Squeeze, I use it to transfer water from one bag or bottle to the other, I use it for filtering from my dirty bag to my clean water bag. I use it so much I keep an extra as a back up so when you order don't get just one or you'll find yourself reordering another.

Makes life easier

I would recommend getting one. I use it with a sawyer filters, just screw this to the filter and the filter to the vecto and it makes filtering water super easy. I fill my 1 liter bottle, and fill my hydration bladder with the bottle, and this adapter makes it so easy.

Essential and a perfect fit

These couplings are essential for back flushing and setting up other systems with Sawyer filters. I only needed one, but I could see easily losing one, so I picked up two.
