Borosilicate Glass Tri Clamp Sight Glasses — 316 SS

These sight glasses are rated for a maximum operating pressure of 150 PSI. The temperature range spans from -40°C to 500°C (400°F), making them suitable for demanding industrial environments including high-heat chemical processing and low-temperature pharmaceutical applications.

Yes. The borosilicate glass used in these sight glasses is compliant with FDA 21CFR177.2600 and FDA 21CFR177.1550, and meets 3-A Sanitary Standards as well as USDA approval. This makes them suitable for pharmaceutical-grade, food-safe, and dairy processing applications.

The body is constructed from 316 Stainless Steel, a pharmaceutical and food-grade alloy known for excellent corrosion resistance. The viewing element is borosilicate glass, which provides superior chemical resistance and thermal stability compared to standard soda-lime glass.

These sight glasses are used across pharmaceutical and biotech processing lines, food and beverage sanitary piping systems, chemical and petroleum processing, USDA-regulated dairy and food production facilities, and general industrial fluid monitoring applications where visual inspection of flow is required.

Yes. The seamless tri-clamp end cap ferrule design is compatible with any standard tri-clamp line, clamp, and gasket. This ensures easy integration into existing sanitary process systems without requiring specialty hardware or modifications to the pipeline.

Borosilicate glass offers significantly higher chemical resistance, thermal shock resistance, and mechanical strength compared to standard glass. Its low thermal expansion coefficient makes it ideal for applications with extreme temperature fluctuations, and its inertness makes it safe for use with food, pharmaceutical, and chemical media.
