The Esco Oil Sight Glass (OSG) is the model that started the Visual Oil Inspection product line over 40 years ago. Water wreaks havoc on lubrication systems, causing premature wear. With the OSG, users have an immediate, 360° visual inspection of the oil and the ability to drain any accumulated water. The OSG, often referred to as a BS&W bowl or water separator, can be 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 oil sight glass where, upon inspection, the user can determine the appropriate action.
Heavy-duty, monolithic oil inspection tool with hexagonal bottom for easier installation. The new Hex-Duty OSG is made of a single piece of UV resistant acrylic . Stronger and more durable, with double the pressure rating at 400 psi. The concave interior bottom allows for easy water draining. Perfect for industrial applications and harsh environments.
