Often referred to as BS&W bowl (bottom sediment and water bowl), our Oil Sight Glass (OSG) can play a critical role in early detection of contamination and allow for constant monitoring of what’s in your oil that can decrease equipment life. Users have an immediate, crystal-clear visual inspection of the oil and a magnified view of the presence of sediment, thanks to an innovative white bottom design. The OSG has the versatility to be installed vertically or horizontally to a drain port depending on space needs for the application. With the addition of indication marks on the side of the bottle, you can quickly and easily monitor the rate of water accumulation. According to the latest API 610 standard (12th edition, January 2021) the use of a BS&W bowl is now recommended for wet sump oil lubricated pumps to detect the presence of water and other gross contamination.
