Our Des-Case Oil Sight Glasses (OSG) include an innovative white bottom to dramatically increase the visibility of oil contaminants that harm equipment. The drain port configuration allows some models 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.
Contact us to include an optional magnetic drain valve to capture ferrous particles for analysis.
