Norgren L74M-4AP-QPN Air Lubricator 1/2 Inch Npt

Product Description

The NORGREN L74M-4AP-QPN is a standard micro fog compressed air lubricator designed for use in pneumatic systems that require consistent oil mist delivery to downstream components such as cylinders, valves, and air tools. Built with an aluminum body and a polycarbonate bowl, this unit provides durable construction alongside visible oil level monitoring. It features a 1/2 inch NPT port and a manual drain, making it a straightforward inline lubricator for general compressed air service. The overall height is 8.81 inches and the overall width is 3.15 inches. This lubricator is installed and serviced by industrial maintenance technicians, pipefitters, and pneumatic system specialists.

The L74M-4AP-QPN is suited for industrial and commercial pneumatic applications where air-line lubricators are required to protect actuators, pneumatic motors, and control valves from wear. Its micro fog design delivers fine oil particles that travel efficiently through the air line to downstream components. This unit is typically installed as part of a filter-regulator-lubricator (FRL) assembly or as a standalone lubricator in a compressed air distribution system. It is appropriate for use in manufacturing, maintenance, and process automation environments.

Key Features

• 1/2 inch NPT port for direct inline installation in compressed air systems
• Aluminum body construction for durability in industrial service environments
• Polycarbonate bowl allows visual monitoring of oil level during operation
• Manual drain for controlled oil reservoir servicing
• Compact form factor at 8.81 inches high and 3.15 inches wide

Compatibility

Designed as an OEM-style replacement or direct installation lubricator for standard 1/2 inch NPT compressed air lines in industrial pneumatic systems.

Installation Notes

Installation is typically performed by a licensed pipefitter or qualified industrial maintenance technician. Depressurize and isolate the compressed air line completely before installing or servicing this lubricator. Ensure the unit is oriented correctly per the flow direction arrow on the body, and verify that downstream components are compatible with oil-mist lubrication before placing the system back in service. Refer to applicable compressed air system codes and the site safety plan when working on pressurized pneumatic lines.
