The Problem With Small Oil Filler Openings
Many aircraft engines, gearboxes, and hydraulic reservoirs have oil filler openings smaller than 18mm in diameter. Standard filler tools do not fit. The result is improvised filling – oil spills, overfilling, and the risk of contamination entering the system during servicing.
TheCanKey Cut-To-Size Filler Nozzles solve this directly.
What Is Included
Each set contains two transparent PE plastic components:
|
Cut-To-Size Nozzle Trimmable to match the exact diameter of any filler opening under 18mm. Trim once, fit precisely, fill cleanly. One size adapts to all. |
Cap Nozzle Seals the open nozzle between uses – preventing dust, debris, and contamination from entering during handling and storage. |
The transparent design gives maintenance personnel full visibility of oil flow during filling – helping avoid overfilling and spills on every service.

in combination with a TheCanKey FunnelCap — sold separately.
Select the FunnelCap that matches the container you are pouring from:
-
FunnelCap | Bottle Cap
— for plastic oil bottles -
FunnelCap | Quart Can
— for one-quart turbine oil cans -
FunnelCap | Gallon Can
— for gallon cans and hydraulic fluid containers
Limited space or a short distance to the filler port?
Consider adding a
Short Flex Hose (9″)
— designed for restricted access and tight engine bays where a rigid nozzle cannot reach.
