Gravity filler cap & adapter

Eaton’s fuel filler adapter assembly uses the power of gravity to fill the airplane. Incorporating a flapper-type check valve, our adapter minimizes fuel loss in the event of fuel cap failures or cap losses. The flapper also prevents damage to the lower wing skin by limiting refueling nozzle insertion depth.
