Add lubrication to your air supply to extend the service life of air-powered tools and equipment. These lubricators have either a clear bowl or a sight glass so you can check the oil level for refilling. Adjust the amount of lubricant in the air based on your equipment's performance. If your machine is running loudly or showing signs of wear, increase the amount; if you notice oil building up, decrease it. Install these lubricators in your air line after filters and regulators.

Aluminum and zinc bowls are stronger than plastic bowls, so they won't crack or shatter if dropped.
