A better alternative to oil reservoir sight windows
Esco has developed a product to make the job of a lubrication technician or maintenance manager easier. The standard sight windows on oil reservoirs make it difficult to view the oil level, they also stain easily and need to replaced quite often. Lubrication Engineers has replaced the traditional sight plug with a sight window called the 3-D BullsEye.
The 3-D BullsEye is a clear cylinder made from a solid piece of acrylic with threading on one end and a rounded polished end on the other side, for easily viewing the oil. The sight window is simple to install provides constant oil monitoring from any angle.
