Pro-source UL-02NAL Air Lubricator 1/4 Inch Npt Aluminum

Product Description

The PRO-SOURCE UL-02NAL is an intermediate compressed air lubricator designed to deliver controlled oil mist into a pneumatic system, reducing friction and wear on downstream tools, cylinders, and valves. The body and bowl are both aluminum construction, keeping weight low while providing solid corrosion resistance in typical shop and industrial environments. The 1/4 inch NPT port accommodates standard compressed air line connections. With a 4.3 oz bowl capacity and an integrated sight glass, operators can monitor oil level without removing the bowl. A bowl guard is included for additional protection against impact and debris. This lubricator is installed by maintenance technicians, pipefitters, and pneumatic system specialists.

The UL-02NAL suits intermediate-duty pneumatic circuits in light industrial, manufacturing, and workshop settings. It supports modular connection, making it compatible with matched filter and regulator units in FRL (filter-regulator-lubricator) assemblies. The 1/4 inch NPT port size fits common small-bore pneumatic lines serving air tools, actuators, and similar components. NBR seals provide reliable performance with standard petroleum-based air line oils. This unit is appropriate for residential shop setups and light commercial pneumatic systems where intermediate lubrication is specified.

Key Features

• 1/4 inch NPT port for direct connection to standard compressed air lines
• Aluminum body and aluminum bowl for lightweight, corrosion-resistant construction
• 4.3 oz bowl capacity supports extended service intervals between refills
• Integrated sight glass allows visual oil level monitoring without disassembly
• Modular connection design enables inline FRL assembly with compatible filter and regulator units
• Bowl guard included for impact and debris protection in shop environments
• NBR seal material compatible with standard petroleum-based pneumatic oils

Compatibility

Designed as an OEM-style intermediate lubricator for 1/4 inch NPT compressed air systems. Supports modular FRL assembly configurations where compatible filter and regulator components share the same port size and modular connection standard.

Installation Notes

Installation is performed by qualified maintenance technicians or pipefitters. Depressurize and bleed the compressed air line completely before removing or installing any FRL component. Apply thread sealant appropriate for compressed air service to NPT threads and tighten to hand-tight plus a standard turn — do not overtighten aluminum-bodied fittings. Verify oil level in the sight glass before returning the system to service and confirm drip rate per equipment manufacturer guidelines before resuming pneumatic tool operation.
