Wilkerson L18-03-KL00B Air Lubricator 90 Cfm 3/8 Npt

Product Description

The WILKERSON L18-03-KL00B is a standard compressed air lubricator designed to introduce controlled amounts of oil mist into a compressed air system, protecting downstream pneumatic tools, actuators, and valves from premature wear. Built to Series 18 specifications, this unit features a 3/8 inch NPT port, an aluminum die cast body, and an aluminum bowl with a 4 oz capacity. It supports airflow up to 90 CFM, making it suitable for moderate-demand industrial and commercial pneumatic circuits. A licensed HVAC, industrial maintenance, or compressed air system technician typically installs and services this component as part of a filter-regulator-lubricator (FRL) assembly.

This lubricator is well suited for use in compressed air distribution lines serving pneumatic tools, cylinders, and control components in light-to-medium industrial environments. It is rated for a minimum working temperature of 14 degrees F (-10 degrees C), making it appropriate for most indoor compressed air applications. The unit supports modular connection for inline FRL assembly configurations and includes a sight glass for easy oil-level monitoring. Manual drain operation allows the technician to service the bowl on a scheduled basis.

Key Features

• 90 CFM airflow capacity suitable for moderate pneumatic demand circuits
• 3/8 inch NPT port with standard NPT end connections for direct inline installation
• Aluminum die cast body and aluminum bowl for lightweight durability
• 4 oz bowl capacity with included sight glass for quick visual level checks
• Manual drain for scheduled service without full disassembly
• Modular connection support allows integration into FRL assemblies
• Nitrile seal material compatible with standard compressor oils

Compatibility

Designed as an OEM-style replacement or new-installation lubricator for compressed air systems requiring a 3/8 inch NPT inline lubricator in Series 18 modular FRL configurations.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system safety procedures. Depressurize and lock out the compressed air line before installing or servicing the unit. Ensure airflow direction matches the directional arrow on the body, and verify all NPT threads are properly sealed with thread sealant tape or compound rated for compressed air service. Confirm oil type used is compatible with nitrile seals and with the downstream components in the circuit.
