SPI Sight Glasses

Sight glasses from Stainless Products (SPI) are engineered for hygienic processing industries and are offered in three options which allow processes to be monitored visually without exposure to the outside elements. Inline and cross type sight glasses are useful for tracking color or consistency when transferring product. Tank glasses allow for fermentation or other processes to be monitored in the midst of operation. They are often installed as a semi-permanent fixture on a variety of tanks.

All SPI sight glasses are 3-A certified and come apart for easy cleaning.
