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 1/8” male NPT outlet to mount directly to a pipe.  The reservoir diameter is 2” and the total height of the unit is 4".

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