Single Feed Manual Lubricators are ideal for continuous operation. Liquid is dispensed when the lubricator is turned on with a toggle shutoff (using the toggle does not affect the metering adjustment).
The reservoir and sight are vented to allow liquid to reach the brush by gravity. An adjustable precision needle valve controls the flow rate; it has a friction lock to guard against loosening from vibration. Drop feeding can be observed through the glass viewing window in the valve body.
This oiler features a polycarbonate reservoir, polypropylene base, aluminum alloy valve body, plated steel shank and Buna-N seals. The pipe mounting has a 1/2” Male NPT thread. The diameter of the reservoir is 3 5/8” and the total height of the lubricator is 11 15/16”.
