Pro-source UL-08N Air Lubricator 1 Inch Npt 8 Oz Bowl

Product Description

The PRO-SOURCE UL-08N is a heavy-duty compressed air lubricator designed to introduce controlled amounts of oil into a pneumatic system downstream of a filter and regulator. It features a 1 inch NPT port, an aluminum body, and a polycarbonate bowl with a sight glass for oil-level monitoring. At 9.25 inches tall and 4.31 inches wide, this unit is sized for industrial and commercial air lines where reliable lubrication of pneumatic tools, cylinders, and valves is required. The NBR seal material provides compatibility with standard petroleum-based lubricating oils used in compressed air service.

The UL-08N is suited for use in industrial facilities, manufacturing lines, maintenance shops, and heavy commercial pneumatic systems. It is typically installed as part of a filter-regulator-lubricator (FRL) assembly on compressed air distribution lines. The modular connection feature allows it to be joined directly to compatible PRO-SOURCE filter and regulator units without additional fittings, simplifying installation in new or retrofit FRL setups. It is appropriate for applications requiring consistent tool and actuator lubrication in continuous-duty environments.

Key Features

• 1 inch NPT port accommodates high-flow compressed air lines
• Aluminum body construction for durability in industrial environments
• Polycarbonate bowl with integrated bowl guard for oil level visibility and protection
• 8 oz bowl capacity reduces refill frequency in continuous-duty applications
• Includes sight glass for at-a-glance oil level monitoring without disassembly
• Modular connection design for direct coupling with compatible FRL components
• NBR seals compatible with standard petroleum-based pneumatic lubricating oils

Compatibility

Designed as an OEM-style heavy-duty compressed air lubricator for 1 inch NPT pneumatic air lines and FRL assemblies in industrial and commercial compressed air systems.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or maintenance professional. Depressurize and isolate the air line completely before installing or servicing this lubricator. Mount the unit vertically with airflow in the direction indicated on the body, and ensure all NPT threads are properly sealed with thread sealant appropriate for compressed air service. Do not exceed the pressure rating of the system or use lubricants incompatible with polycarbonate bowl materials.
