3-D BullsEye - A Better Alternative to Sight Windows on Oil Reservoirs
Esco has developed a product to make the job of a lubrication technician or maintenance manger easier. The standard sight windows on oil reservoirs make it difficult to view the oil level, stain easily, and must be replaced often. Our team at Esco has improved upon the old-fashioned sight plug with the creation of a replacement sight window called the 3-D BullsEye.
The 3-D BullsEye is a clear cylinder made from one solid piece of acrylic with threading on one end and a rounded polished end for easier viewing of the oil on the other. Easily installed by wrapping the threads with Teflon tape, the 3-D BullsEye provides constant oil monitoring from any angle.
The image on the left is of a standard sight window through which it nearly impossible to see the oil. See how easy it is to monitor oil level and quality once the 3-D BullsEye is installed! Just walking by, the lubrication maintenance professional can inspect the reservoir oil.
