Pipe sight glasses allow quick, reliable visual inspection of liquid flow or levels within pipe systems, tanks, gear cases, bearing housings, and mixers. Constructed from durable steel with a nickel-plated surface, these fittings are designed to withstand demanding conditions while providing clear visibility of fluid movement and levels. The glass window is permanently fused to the housing, ensuring strength, leak resistance, and long service life. The sight glasses with a built-in reflector improve contrast in low-light conditions for dark liquids. The sight glasses with a built-in reflector and ball indicator show liquid movement or level changes from a distance. The sight glasses with a built-in bullseye lens enhance visibility at different angles or at a distance in clear or low-contrast fluids.
