Oil Sight Glass

Des-Case Corp. has developed a redesigned oil sight glass (OSG) engineered to provide increased visibility, durability and versatility for visual oil analysis. A clear cylinder that installs in the drain port of the oil reservoir of pumps, gearboxes, bearing housings and other equipment, the sight glass can provide continuous monitoring of the clarity, color, sediment and water contamination of the equipment’s oil.

The new OSG has a white bottom intended to enhance visibility, along with dual mount versatility for use in both horizontal and vertical applications. The polyamide casing provides a clear view and can withstand tough environments, Des-Case said.

Other improvements include a sloped floor for better sediment drainage, indication marks to easily monitor accumulation of water and improved UV resistance and compatibility with all gear and mineral oils, most synthetic oils and diesel.
