Bulls Eye Sight Glasses For Tanks – N150 Series – Gulf Coast Glass

These bull's eye sight glasses are used to observe the level of a tank at a specific point within it. Thanks to their direct view into the interior, they allow for the observation of not only the level but also atypical conditions within the system, such as bubbling, evaporation, and changes in coloration.

The most common connection is with NPS (National Pipe Standard) straight threads, which create the seal at the base of the tank. For installation, these sight glasses already include the seals that seal against the tank wall.

GULF COAST GLASS brand bull's eye sight glasses, N150 series, are designed to operate at 150 PSI. Depending on the temperature, appropriate glass and seals can be recommended. They can be manufactured in brass, stainless steel, or carbon steel.

These sight glasses, manufactured according to the N150 series, make it easy to observe the level, as they have a perforated surface on the back painted in white, allowing for quick level observation due to the contrast it creates with the background color.
