The Platypus Quick-Disconnect Kit: This handy little add-on splices into any Platy tubing (or other 1/4” inner diameter tubing) to enable quick and spill-proof removal of hoses allowing you to refill your reservoir without rerouting your hose through your backpack.
Purchased this item to use with the Platypus gravity filter system. Splicing in a 1/4 plastic 'y' and this item enables a seperate water supply to be connected for fillig a glass or small pot.
