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

Product Description

The PRO-SOURCE NUL-04N is a standard compressed air lubricator designed to deliver controlled oil mist into pneumatic lines, protecting downstream tools, actuators, and valves from wear. The unit features an aluminum body and a polycarbonate bowl with a built-in sight glass, allowing technicians to monitor oil level at a glance. NBR seals provide reliable compatibility with standard pneumatic oils. At 9.65 inches tall and 2.36 inches wide, the NUL-04N is a compact unit suited for inline installation in compressed air distribution systems. Licensed industrial mechanics and pneumatic system technicians are the primary installers.

The NUL-04N is used in industrial and commercial compressed air systems where downstream pneumatic components require continuous lubrication. It is suited for shop air lines, production equipment, and maintenance stations. The 1/2 inch NPT port accommodates common mid-range air line sizes. The 4.3 oz bowl capacity is appropriate for light-to-moderate duty lubrication cycles. A bowl guard is included for added protection in environments where incidental contact is a concern. The modular connection design supports use in filter-regulator-lubricator (FRL) assemblies.

Installation Notes

Installation should be performed by a qualified industrial mechanic or pneumatic systems technician. Depressurize and lock out the compressed air supply before installation or bowl servicing. Ensure the lubricator is installed in the correct flow direction as indicated on the body. Use thread sealant appropriate for pneumatic systems on all NPT connections and verify all fittings are leak-free before returning the system to service.
