Poppet Adjustment Tool

The poppet on any Underwing Refuelling Nozzle must be set correctly after maintenance. If the poppet protrudes too far out of the underwing Refuelling Nozzle it can fail to seal correctly when the nozzle is closed and stowed. If the poppet is set too far onti the Underwing Refuelling Nozzle body then it can cause deformation of the nose seal which will lead to leakage when connected to the aircraft. This tool enables a quick and easy check to ensure that the poppet on Eaton's Carter 60427, 64348 or 64349 nozzles has been set in accordance with the parameters set out in the maintenance manual.
