Large Automatic Bottle Filler (7/16" & 1/2'' tubing)
This dual purpose bottle filler attaches to 7/16" & 1/2" ID syphon tubing. Like our popular 5/16"-3/8" model, this can operate with or without the internal spring. Once the syphon has started, clamp off & attach this filler. Simply push down in bottle to open valve at the tip. Fill bottle to the brim, release and flow will cease. Remove filler and the displacement should leave the proper head space in the bottle.
