Wilkerson L18-03-KK00B Air Lubricator 90 Cfm 3/8 Npt

Product Description

The WILKERSON L18-03-KK00B is a standard compressed air lubricator designed to introduce controlled amounts of oil mist into downstream pneumatic lines. It serves as a critical component in compressed air preparation systems, protecting actuators, valves, and air-powered tools from premature wear caused by dry running conditions. The unit features a 3/8 inch NPT port, a rated flow capacity of 90 CFM, and an aluminum die cast body with a polycarbonate bowl. It is installed by industrial maintenance technicians, pipefitters, and pneumatic system specialists working on compressed air distribution and point-of-use service equipment.

The L18-03-KK00B is suited for use in both light industrial and general manufacturing environments where pneumatic components require consistent lubrication. It fits into compressed air preparation assemblies alongside filters and regulators and is rated for operation down to 14 degrees F, making it appropriate for unheated facilities or outdoor enclosures in moderate climates. Its modular connection design allows integration into FRL (filter-regulator-lubricator) assemblies. The manual drain and bowl guard are practical features for maintenance technicians who service equipment on regular intervals.

Key Features

• 3/8 inch NPT port with NPT end connections for standard compressed air line integration
• 90 CFM flow capacity suitable for moderate-demand pneumatic circuits
• Aluminum die cast body provides durability in industrial service environments
• Polycarbonate bowl with integrated bowl guard for visibility and protection
• Sight glass included for monitoring oil level without disassembly
• Modular connection design compatible with Series 18 FRL assembly configurations
• Manual drain for controlled maintenance cycles

Compatibility

Designed as an OEM-style replacement and new-installation lubricator for Series 18 compressed air preparation systems requiring a 3/8 inch NPT port connection.

Installation Notes

Installation should be performed by a qualified maintenance technician or pipefitter. Depressurize and lock out the compressed air supply before servicing or installing any compressed air line component. Apply thread sealant appropriate for pneumatic service to NPT connections and verify all fittings are leak-free before returning the system to pressure. The lubricator should be mounted vertically with the bowl oriented downward per standard FRL assembly practice.
