Rucker NL12-400-OPL Pneumatic Lubricator

Rucker NL12-400-OPL Pneumatic Lubricator is a compact in-line device designed to introduce lubrication into compressed-air systems. It features a 1/2 in NPT connection and is rated for operating pressures up to 150 psi. In operation, a controlled amount of oil is added to the air stream to lubricate downstream components, helping to reduce wear in cylinders, valves, and pneumatic tools. The NL12-400-OPL designation places it within Rucker’s NL lubricator family, aligning with standard in-line install practices for factory air lines. For best results, install the lubricator near the point of use to ensure reliable lubricant delivery along the line and to minimize maintenance downtime.
