Aro-Flo Series Air Line Lubricator, 3/8 NPT Ports, 85 SCFM Flow Rating

With 3/8 NPT ports, it matches standard 3/8 NPT air line fittings, so it’s set up to thread into a 3/8 NPT system without needing a port adapter just to make the connection.

At 85 SCFM, this unit handles a solid range of general pneumatic tool setups without choking airflow. The oil delivery adjusts to match the flow rate, so the ratio stays consistent whether demand fluctuates or stays steady. As long as your combined tool demand doesn't push past that 85 SCFM ceiling, wear reduction is exactly what it's built for. Keeping it installed close to the downstream tools also helps make sure the oil mist actually reaches the equipment before it settles out.

That 85 SCFM flow rating is what you'll want to pay attention to. This lubricator should keep your impact wrench humming as long as your supply is steady.
