DEF auto shutoff nozzle.   Compatible with any 120 volt suction pumps on totes and barrels or the self loading tank with 12 volt suction pump. Stainless Steel nozzle and 3/4" hose barb connector.
Please note:
The auto shutoff nozzle will not operate well with our standard freeze tolerant internal submersible pumps.   It takes a chambered pump to deliver the back pressure required to operate the auto shutoff feature.  A chambered pump can not be freeze tolerant. If you only pump at ground level it will operate but you will lose the high lift capability of the pump.
