The aluminum pressure feed line oiler is a made-in-USA in-line lubricator that meters a controlled amount of oil into a pressurized air line, keeping downstream pneumatic tools, valves and bearings lubricated every hour they run. A cast aluminum body keeps the unit lightweight and corrosion resistant, a sight glass shows oil level and flow at a glance, and a metering adjustment screw regulates the feed rate. Threaded NPT inlet and outlet ports come in 1/2, 3/4 and 1 in. sizes.

Pressure-feed metering uses the supply lines own pressure differential to push oil into the airstream instead of relying on a gravity drip. Fill the reservoir with pneumatic tool and rock drill oil and plumb the oiler upstream of a paving breaker or rock drill; Crowder Supplys other hose oilers cover additional capacities and styles.
