Oil Reservoirs, or Oil Cups, use gravity to dispense liquid.  They are designed to serve as a central reservoir of an oiling system. 

This polycarbonate reservoir with a polypropylene base is suitable for temperatures up to 225° F. It features a cap that swivels out of the way for easier filling, while remaining attached to the reservoir.  Buna-N seals are used.  There is a 1/8” female NPT outlet with a 5/8”-18 thread for remote mounting.  The reservoir diameter is 2” and the total height of the unit is 3 1/4".

Additional shutoff and sight feed valves are needed for the regulation of liquid flow (see “Oil Flow Control Valves”).
