Platypus - GravityWorks Push-Pull Cap Adapter

Sometimes the most useful piece of gear is the one that makes everything else work together better.

The GravityWorks Push-Pull Cap Adapter is a small but genuinely handy accessory for anyone running a Platypus gravity water filter system. It connects the clean hose output directly to any water bottle fitted with a push-pull cap, letting you filter straight into your bottle without managing an open vessel or worrying about spills. For paddlers and backpackers who already carry a push-pull cap bottle as their daily drink bottle, this removes one extra step at the end of a long day on the water.

It also works as a line-in connector, threading into a hydration reservoir's drink tube or shutoff valve once the bite valve is removed, so you can filter directly into your pack reservoir. Compact and ultralight, it's the kind of small adapter that quietly earns its place in your kit.
