These are for gas station pressure pumps and have an automatic shut off when fuel level is high, however they do not have a hold open rack (user must hold the nozzle, self-service). They are NOT designed for lower flow pumps, such as farm tank, off-road, or truck mounted pumps (preset Service Station shut off won't work at low flow). Standard nozzles rated down to -40°C (-40°F). Typically 3/4" Spout for gasoline, 1" for diesel.

Warning: <<Not for farm tank, gravity, truck mount low flow systems>>
