Sight Glass Assemblies Manufacturer in India
Sight glass assemblies are precision-engineered viewing devices designed to provide visual observation of process fluids, flow conditions, and operational status in pipelines, tanks, vessels, and process equipment. These critical visual inspection components enable operators to monitor liquid flow, detect contamination, verify color and clarity, observe phase separation, confirm CIP/SIP effectiveness, and troubleshoot process issues in real-time without system interruption. Available as inline sight glasses, circular sight glasses, tubular sight glasses, sanitary sight glasses, and illuminated sight glasses, these assemblies are manufactured to meet stringent requirements for pharmaceutical, food processing, dairy, beverage, chemical, and industrial applications.

The inline sight glass (also called flow sight glass) is installed directly in the pipeline to provide continuous visual monitoring of fluid flow, enabling operators to detect flow stoppage, air entrainment, particulate contamination, or phase changes. Circular sight glasses feature round viewing ports mounted on tank walls, vessel heads, or pipeline elbows, providing visual access for level observation, color verification, or process monitoring. Tubular sight glasses incorporate cylindrical glass tubes offering 360-degree viewing capability, ideal for observing liquid columns, interfaces, or flow patterns.
The sanitary sight glass (also called tri-clamp sight glass) features hygienic design with electropolished stainless steel construction, smooth internal surfaces, and quick-release tri-clamp connections meeting 3-A Sanitary Standards and FDA requirements. Illuminated sight glasses incorporate integral LED lighting systems that enhance visibility in dark environments, low-light conditions, or when viewing clear/colorless fluids. The sight glass with wiper includes a mechanical wiper blade operated externally to clean the glass surface during operation, maintaining clear visibility without system shutdown.
Union sight glasses feature threaded union connections enabling easy installation, removal, and glass replacement without cutting piping or breaking flanges. Flanged sight glasses provide robust mounting for high-pressure applications, incorporating reinforced construction and heavy-duty flanges per ASME or DIN standards. Welded sight glasses offer permanent, leak-free installation with butt-weld or socket-weld end connections for critical applications. Additionally, sight glass assemblies manufactured with premium borosilicate glass offer exceptional thermal shock resistance, chemical durability, and optical clarity, while tempered glass or laminated safety glass options provide enhanced impact resistance and safety protection.
Furthermore, SS 304 sight glasses provide excellent corrosion resistance for general food processing and industrial applications at economical prices, while SS 316 sight glasses offer superior chemical resistance for pharmaceutical, aggressive chemical service, and marine environments due to their molybdenum content.
As a leading sight glass assemblies manufacturer in India and trusted sanitary sight glass manufacturer India, we specialize in delivering high-quality visual inspection solutions that conform to international standards including ASME B16.34, DIN 28120, ISO 2852, 3-A Sanitary Standards, ASME BPE, and EHEDG guidelines. Our comprehensive product range includes various sight glass configurations designed for specific process conditions, visibility requirements, and mounting arrangements. Whether you need inline sight glasses for pipeline monitoring or hygienic sight glasses for pharmaceutical clean rooms, our manufacturing facility is equipped with advanced machining, precision glass processing, electropolishing, and pressure testing capabilities to meet your exact specifications.
