Providing Quality Oil Care to Industry

Des-Case Oil Sight Glasses

With the new and improved oil sight glass (OSG), our engineers reimagined how an oil sight glass plays a critical role in early detection of contamination and allows for constant monitoring of what’s in your oil that can decrease equipment life. Users have an immediate, crystal-clear visual inspection of the oil and a magnified view of the presence of sediment, thanks to an innovative white bottom design. The new OSG has the versatility to be installed vertically or horizontally to a drain port depending on space needs for the application. With the addition of indication marks on the side of the bottle, you can now quickly and easily monitor the rate of water accumulation.
