3" Tri Clamp Sight Glass — 316 Stainless Steel

This tri clamp sight glass is rated for a maximum operating pressure of 150 PSI. This rating makes it suitable for a wide range of industrial, food processing, and pharmaceutical piping applications. Always verify that your system's operating conditions fall within this rated limit before installation.

The sight glass supports a minimum temperature of -40°C and a maximum temperature of 400°F (500°C). This broad range accommodates cryogenic-adjacent applications as well as high-heat processing lines in pharmaceutical, chemical, and food manufacturing environments.

Yes. The tri-clamp end cap ferrule design ensures compatibility with any standard tri-clamp line, clamp, and gasket. This makes it a drop-in solution for existing sanitary piping systems without requiring special adapters or modifications to your process line.

Yes. The borosilicate glass used in this sight glass complies with FDA 21CFR177.2600 and 21CFR177.1550, and is approved by 3-A Sanitary Standards and the USDA. This makes it fully suitable for food-grade, dairy, nutraceutical, and pharmaceutical processing applications.

The Tri Clamp End Cap Sight Glass is available in five sizes: 1.5", 2", 3", 4", and 6". Each size is constructed from 316 stainless steel with a seamless tri-clamp end cap ferrule and borosilicate glass, maintaining the same pressure and temperature ratings across all sizes.

This sight glass is widely used in pharmaceutical and biotech processing lines, food and beverage sanitary piping, chemical and petroleum handling systems, USDA-regulated dairy facilities, and general industrial fluid monitoring applications. Its multi-standard compliance makes it a versatile choice across heavily regulated industries.
