The Des-Case Oil Sight Glass and Level Monitor provides continuous and instantaneous monitoring of oil including the level. It comes in standard heights from 3” to 24″, to correspond to the distance from the oil reservoir access port and the maximum height the oil will reach, and can be customized for special applications.
OSGL allows the user to view the oil colour, clarity and accumulation of water or other contaminates. The strong, clear cast acrylic body allows for viewing of the level. The spring loaded drain valve is positioned to quickly discharge any water before it damages the oil lubricity. Red and green Buna O-rings are included with the OSGL to mark upper and lower limits, or to designate running oil level and idle oil level. Each Visual Inspection Sight Glass & Level Monitor comes with a 2 micron breather, which allows the oil level to equalize with the level inside the system. If you require a closed loop system, install the OSGL without the breather and use the top opening to port back into your equipment.
A Dual Port Oil Sight Glass & Level Monitor version is available with a second 3/8″ NPT port opposite the installation nipple to allow the installation of a Sample Port for oil sampling.
The Oil Sight Glass and Level Monitor is effective in most operating environments with the maximum temperature rating of 230 °F and the maximum pressure rating of 265#. (Operating Temperatures and Pressures: 180°F to 265 PSI, 203°F to 66 PSI, 230°F at atmospheric pressure).
