The Esco Oil Sight Glass
The original Esco Oil Sight Glass handles most applications
The Esco Oil Sight Glass (OSG) is the model that started the product line over 30 years ago. Water wreaks havoc on lubrication systems, causing premature wear. With the OSG, users have an immediate visual inspection of the oil and the ability to drain any accumulated water. The OSG is installed directly to a drain port located at the bottom of a reservoir or with an elbow for drain ports located on the side of the equipment. The spring loaded drain valve is utilized to drain off any water contamination. Any sediment or particles in the lubricating fluid will matriculate to the OSG where, upon inspection, the user can determine the appropriate action. The Oil Sight Glass 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).
