OPW 7HB® Series Automatic Diesel Nozzle Description

The OPW 7HB® Series Automatic Diesel Nozzle is built for modern self-service and card-lock fueling systems, offering reliable spill prevention with every use. It's engineered to stay closed until your system is pressurized, the 7HB only activates when it's safe and automatically shuts off when pressure drops.

This FlowLock™ feature means it's already sealed when it’s returned to the dispenser, reducing drips, spills, and environmental risk. With a 1" NPT inlet and an easy-to-replace 1 3/16" O.D. spout, this fuel nozzle is engineered for durability, control and is well-trusted in the field.

Available in black, green, and yellow, the 7HB series helps operators color-code for efficiency and compliance.
