Our Oil Level gauge is a very simple brass and heat proof glass tubular level gauge unit to provide level indication, primarily on oil tanks. As standard they are fitted from the base, but a double banjo fitting on top and bottom is also possible.. Please check the data sheet below for the various fitting options.. If you need a connection not listed, let us know and we can prepare and adaptor. The oil sights work on an open circuit.. The brass guard offers the glass great protection against accidental damage, yet still providing a clear visual.


This simple unit is ideal for small tanks where you need to always have a visual on the oil level. For clearing simply remove the top cap and the tubes can be removed, replacement glass tubes can always be supplied on request.
