Pro-source NUL-04NAL Air Lubricator 1/2 Inch Npt

Product Description

The PRO-SOURCE NUL-04NAL is a standard compressed air lubricator designed to inject a metered amount of oil into a pneumatic system's airstream, protecting downstream tools, cylinders, and valves from wear and corrosion. Built with an aluminum body and aluminum bowl, this lubricator accepts a 1/2 inch NPT port connection and stands 9.65 inches tall with a 2.36 inch width. A sight glass is included for easy oil-level monitoring without shutting down the line. It is suited for use in FRL (filter-regulator-lubricator) assemblies and standalone pneumatic circuits serviced by industrial maintenance technicians and pipefitters.

This lubricator is intended for use in compressed air systems requiring continuous lubrication of pneumatic components such as air motors, impact tools, and actuators. The 4.3 oz bowl capacity provides a practical service interval for light to moderate duty applications. The modular connection design allows integration into multi-unit FRL assemblies, making it a straightforward replacement or new-installation component in both shop and industrial environments. A bowl guard is included to protect the bowl during operation.

Key Features

• 1/2 inch NPT port size for common pneumatic line connections
• Aluminum body and bowl construction for lightweight corrosion resistance
• NBR seal material compatible with standard petroleum-based pneumatic oils
• Includes sight glass for visual oil level inspection without line shutdown
• Bowl guard included for added protection in shop environments
• Modular connection supports FRL assembly configurations

Compatibility

Designed as an OEM-style replacement or new-installation lubricator for standard compressed air systems with 1/2 inch NPT porting.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pipefitter. Depressurize and lock out the compressed air supply before removing an existing lubricator or installing this unit. Apply thread sealant appropriate for pneumatic service on all NPT connections and confirm all fittings are leak-free before returning the system to service. Orient the lubricator vertically per standard FRL installation practice to ensure proper oil feed.
