Viewports can be used to monitor oil levels within a sump housing and provide visual inspection of lubricant condition. Viewports with Baffles are used in turbulent conditions.
To resist corrosion, these viewports are offered in brass or zinc plated steel bodies. The lenses can be removed in the field for cleaning, rather than purchasing and installing a new viewport.
