Platypus - In Line Adapter for GravityWorks

Exceptionally light and easy to use, the Push/Pull Adapter allows any GravityWorks(TM) system to filter directly into any Platy bottle fitted with a Push/Pull cap. For filtering directly into your hydration reservoir, simply remove the blue end and plug the white adapter directly into your hydration hose or shutoff valve with the bite valve removed. Refilling a reservoir in the field was never so easy.
