Oil Sight Glasses
The Oil Sight Glass product line consists of the original Oil Sight Glass, the Oil Sight Glass & Level Monitor, the Oil Level Indicator, and the 3-D BullsEye. Products available through our partnership with Esco Products, Inc. provide lubrication management professionals with a complete and immediate visual oil analysis.

It provides continuous fluid monitoring of clarity, color, sediment, and water contamination. The drain valve allows for
