Horizontal Style Oil Sight Glasses

Esco Products Horizontal Oil Sight Glass

Horizontal Style When Access is Limited

The Horizontal Mounted Oil Sight Glass provides continuous fluid monitoring of the clarity, color, sediment and water contamination by allowing operators the ability to see your oil, monitor it and drain the water accumulation as soon as it appears for equipment that is located too close to the ground to install the Vertical Oil Sight Glass, which is typical for many gear boxes. Minimum ground clearance is not problem, as the eccentric placement of the inlet nipple and outlet drain valve allow for the same efficient functionality of the legacy Oil Sight Glass but in a horizontal position. When the Tattle Tales, Bottom Sediment and Water Bowls, BS&W, Pig Tails or Bulls Eyes cannot do the trick because of limited vertical access, this product is your answer.
