      Extend the life of vehicles and help prevent costly repairs with sight plugs from Grainger. Lube sight checks give a quick visual inspection and show the presence of oil in gear cases, bearing housings, or indicate liquid levels in reservoirs. They are observation windows to check burner flames, gears in motion, relay or switch operation in sealed housing.
