Oil Sight Glasses
Esco Products is a trusted plastic oil sight glass supplier. 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 plastic 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 plastic oil sight glass where, upon inspection, the user can determine the appropriate action.
Premium acrylic, monolithic oil sight glass designed to withstand the harshest environments. An improvement upon the Esco 3-piece Oil Sight Glass, this sight glass is now a single piece of acrylic and offered in 1-ounce or 3-ounce bottle sizes and with either ¼”, 3/8”, ½” or ¾” NPT.Price From: $69.95
