316 Stainless Steel Sight Glasses

These sight glasses are rated to a maximum operating pressure of 150 PSI. The temperature range spans from -40°C on the low end to 500°C (400°F) at the high end. This broad range makes them suitable for cryogenic, ambient, and high-heat process applications across pharmaceutical, food, and chemical industries.

Yes. The borosilicate glass used in these sight glasses complies with FDA 21CFR177.2600 and FDA 21CFR177.1550. The glass material is also approved under 3-A Sanitary Standards and is USDA approved, making it fully suitable for use in pharmaceutical, food processing, dairy, and biotech sanitary piping systems.

The Tri Clamp End Cap Sight Glass is available in five standard tri-clamp sizes: 1.5", 2", 3", 4", and 6". Each size is designed to be compatible with standard tri-clamp lines, clamps, and gaskets, ensuring easy integration into existing sanitary process piping systems without additional modifications.

These sight glasses are engineered for pharmaceutical and biotech processing lines, food and beverage sanitary piping, chemical and petroleum handling systems, USDA-regulated dairy facilities, and general industrial fluid monitoring. Their multi-standard compliance and robust construction make them a versatile solution across regulated and high-purity process environments.

Borosilicate glass offers significantly higher thermal shock resistance, chemical inertness, and mechanical strength compared to standard soda-lime glass. In process piping applications, this means greater durability when exposed to aggressive chemicals, steam, or rapid temperature changes — all while meeting pharmaceutical and food-grade compliance standards like FDA 21CFR and 3-A.

The tri-clamp end cap design provides a secure, leak-resistant seal that integrates seamlessly with any standard tri-clamp line, clamp, and gasket without specialized tooling. It enables quick assembly and disassembly for cleaning and inspection — a critical requirement in CIP/SIP-compatible pharmaceutical, food, and biotech processing environments where sanitation and uptime are essential.
