The U406 is designed to be installed on fuel dispensing hoses,and will separate when subjected to a designed pull force. The dual valves seat automatically, stopping the flow of fuel and limiting any fuel spillage, while protecting the dispensing equipment.
For proper operation, the U406-A/B should be installed with a "straightening"
hose with a minimum length of 9". U406-C/D should be installed with a minimum length of 12" .
