Pro-source UL-03NAL Air Lubricator 3/8 Inch Npt Aluminum

Product Description

The PRO-SOURCE UL-03NAL is an intermediate compressed air lubricator designed to deliver controlled oil mist into pneumatic systems, protecting downstream tools, cylinders, and valves from wear. Built with an aluminum body and aluminum bowl, this unit accepts a 3/8 inch NPT port connection and stands 7.75 inches high with a 2.52 inch width. The lubricator supports modular connection, making it compatible with standard FRL (filter-regulator-lubricator) assembly configurations. A built-in sight glass allows technicians to monitor oil flow rate without disassembly. The NBR seal material provides reliable performance across a broad range of operating conditions. Weighing 1.76 pounds, it is compact enough for panel or inline mounting in most industrial and shop air setups.

This lubricator is suited for use in compressed air lines serving pneumatic hand tools, automation equipment, and production machinery in both light industrial and manufacturing environments. It is typically installed as part of an FRL assembly at the point of use, upstream of air-powered tools or actuators. The modular connection feature allows it to be added to or removed from an existing filter and regulator stack without specialized fittings. Maintenance technicians and pipefitters commonly install this type of unit during initial system commissioning or as a replacement in aging air preparation circuits.

Key Features

• 3/8 inch NPT port size for direct inline installation in standard compressed air lines
• Aluminum body and bowl construction for lightweight, corrosion-resistant performance
• NBR seals compatible with petroleum-based compressor oils
• Integrated sight glass for visual oil flow monitoring during operation
• Bowl guard included to protect the bowl from impact damage
• Modular connection supports integration into FRL assemblies
• 4.3 oz bowl capacity for adequate oil reservoir in typical shop air applications

Compatibility

Designed as an OEM-style replacement or new-installation lubricator for intermediate compressed air preparation systems using 3/8 inch NPT connections.

Installation Notes

Installation is performed by qualified pipefitters or maintenance technicians familiar with compressed air system plumbing. Depressurize and isolate the air line completely before installing or servicing this lubricator. Use thread sealant appropriate for pneumatic fittings on all NPT connections and verify there are no leaks before returning the system to service. Refer to applicable OSHA and NFPA pneumatic system guidelines for safe operating pressure limits.
