Type “AO” Oilers

Type “AO” Stock Oilers are available with the standard 1-quart Reservoir (as shown in the A-9 and A-18 pictures), and with the new 1/2 gallon Reservoirs (shown above).

The “O” in the “AO” stands for the Overflow Valve in the pan. This overflow protection prevents the bottom pan from spilling excess lubricant.
