The Auto Luber automatic lube pot from PipeHunter works with any greaseable swivel union, supplying up to 100 cc of lithium-based grease. Designed for swivel unions and hard-to-reach lubrication points, the luber installs by removing the grease zerk. A visual inspection tells if the supply is running low.
