Sawyer Hydration System Adapter

The Sawyer SP110 adapter is a simple plastic fitting weighing 10 grams that lets you plumb a Sawyer Squeeze-series filter directly inline with a hydration bladder tube. Instead of filtering water into a bottle first and then pouring it into the bladder, filtered water flows straight through the tube to the bite valve, which simplifies the routine at water stops on trail. It fits standard 1/4-inch (6 mm) inner-diameter tubing and is compatible with three filters in the Sawyer lineup: the Squeeze, the Micro, and the Mini Dual Thread. It comes in blue and gray. The adapter does not filter water on its own — it is purely a connector, so the actual filtration performance (removal of bacteria and protozoa) depends entirely on whichever filter is attached. Given its negligible weight, it is a cheap, low-effort upgrade for anyone who already owns a compatible Sawyer filter and wants to run their hydration system inline rather than decanting water by hand.
