Norgren L68M-6GP-MRQ Micro Fog Lubricator - G3/4 Port
Part Number: L68M-6GP-MRQ
Quick Summary
Norgren L68M-6GP-MRQ is a micro fog lubricator designed to deliver precise lubrication for general pneumatic systems. In many installations, inconsistent oil distribution and frequent maintenance downtime erode productivity; this model combats that with a flow-sensing design that maintains a near-constant oil/air ratio across a wide range of flows. The Olympian Plus family offers modular plug-in options and robust mounting compatibility, supporting quick integration into existing lines. With CE compliance and IP-conscious design principles common to this range, it enables safe operation in challenging environments. This combination helps engineers reduce oil waste, simplify service tasks, and scale lubrication for longer pipework while keeping total cost of ownership in mind.

FAQs
The L68M-6GP-MRQ supports the Olympian Plus plug-in system with compatible yoke assemblies (Y68A-6GN-N1N, Y68A-6GN-N2N) and a wall bracket option (18-001-979), enabling quick, modular mounting on existing lines and space-constrained installations.
Key specs include G3/4 port size, maximum inlet pressure of 17 bar, operating temperature -20 to 80 °C, flow around 175 dm3/sec (371 scfm), start point at 6 dm3/sec, and a body/bowl made of aluminum with nitrile elastomer seals. These drive performance in general pneumatic applications.
Yes. The micro fog design delivers fine mist suitable for long pipework, and the flow-sensing system maintains a stable oil/air ratio across varying flow, improving coverage along extended runs and multiple actuators in a network.
Maintenance is facilitated by a manual drain and compatibility with a quick-fill nipple (18-011-021) and the L68M-KIT service kit. Accessories also include mounting yokes and a wall bracket to simplify ongoing servicing and replacement.
The combination of precise oil/air control, modular installation, and easy servicing reduces lubricant waste, lowers downtime, extends tool life, and accelerates commissioning—delivering measurable reductions in operating costs over the system lifecycle.
