Based on the popular FunnelCap for Gallon cans, The FunnelCap with bottle fittings makes it safe and easy to fill piston oil and service aircraft gearbox systems without spilling of oil and without getting FOD in the oil or oil container.

Open half-used oil containers can be stored in the storage room or aircraft without risk of oil leaking out. The flex hose clip ensures a tight seal of the flex hose to the cap stud, and also secures the flex hose to the can to minimize storage space when not in use. The red cap seals the flex hose and ensures a tight seal of the flex hose end.

More flex hoses can be connected to increase the reach.

The flex hose can be removed if desired. The red flex hose cap is then installed on the cover stud and seals to avoid leakage and FOD.
