The Quick Connect Refiller as a whole is true to it's name in that it is truly a Quick Connect nozzle. It can be put on a ball shut off and controlled without shutting down the hose lay or opening and shutting the gate on an engine. Or, it can be changed over from a garden hose nozzle in seconds to fill an empty back-pack pump. AND, it can be stored neatly in small spaces at only 3.5" long.
Just supply your own shut-off valve and this nozzle will:
fill a bladder bag in 30 seconds
fill a blivet in 1 minute
*This nozzle is small and compact for easy storage.
