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

This acrylic reservoir with an aluminum alloy base is suitable for temperatures up to 160° F.  It features a self-closing filler cap.  Buna-N seals are used.  There is a plated steel 1/2” male NPT outlet to mount directly to a pipe.  The diameter of the reservoir is 4 1/4” and total height is 7 11/16”.

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