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 plated steel 1/2” male NPT outlet to mount directly to a pipe.  The reservoir diameter is 3 5/8” and the total height of the unit is 6 13/16".

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