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 when checking both color and clarity of the oil on small wet sump applications such as pumps and gearboxes, while allowing an unobstructed 360°view of the oil level from any angle. 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.
