Light-Integrated Sight Glass Fittings: Combined Sight & Illumination in a Single Port

John Moncrieff’s light-integrated sight glass fittings combine process illumination and visual access into one compact, engineered assembly. Designed for direct mounting on vessels, tanks, silos, mixers, and pipelines, these units deliver bright, focused LED lighting and clear sight into your process through a single hygienic or industrial-grade port.

Available in screwed, clamp, or flanged configurations with integrated LED luminaires, quick-release or hinged closures, and a range of nominal sizes, these fittings reduce nozzle count, simplify installation, and improve operator visibility in non-Ex process areas.
