Oil Sight Glass Level Monitor

The Oil Sight Glass Level Monitor (OSGL) allows you to view oil color and clarity while monitoring the level of the oil in the reservoir. Choose a length from 3″ to 24″ corresponding to the distance from your equipment’s oil reservoir access port to the maximum height the oil will reach. View water accumulation and drain it off with the drain valve. An optional magnetic drain valve also captures ferrous particles for analysis. A dual port version is available with a second 3/8″ NPT port to allow installation of a sampling tube.

Oil Sight Glass

The Des-Case Oil Sight Glass (OSG) includes an innovative white bottom to dramatically increase the visibility of oil contaminants that harm equipment. The drain port configuration allows it to drain water properly whether the sight glass is in a vertical or horizontal orientation. With the indication marks on the side of the bottle, you can quickly and easily monitor the rate of water accumulation. The OSG is available in multiple size and connection options, and an optional magnetic drain valve captures ferrous particles for analysis.
