How is tri clamp measured?

Answered by Rodney Landry

Tri Clamp fittings are commonly used in the food and industry for their sanitary design and easy installation. The measurement of a Tri Clamp fitting is determined by the outside diameter (OD) of the tubing, rather than the diameter of the ferrule flange.

When it comes to Tri Clamp sizes, there are two categories: smaller OD tubing (1/2″ and 3/4″) and larger OD tubing (1″ and 1.5″). For the smaller sizes, the Tri Clamp ferrules sizes are combined for each pair. This means that 1/2″ and 3/4″ Tri Clamp fittings share the same ferrule size, as do 1″ and 1.5″ Tri Clamp fittings.

To measure a Tri Clamp fitting, you need to measure the outside diameter of the tubing that the fitting will be attached to. This can be done using a caliper or measuring tape. Once you have the measurement, you can refer to a Tri Clamp sizing chart to determine the appropriate Tri Clamp size for your tubing.

It's important to note that Tri Clamp fittings are designed to provide a secure and leak-proof connection between two pieces of tubing. The clamp end ferrule is used to hold the two pieces of tubing together, creating a tight seal. The use of a Tri Clamp fitting ensures that the connection is sanitary and easy to clean, making it ideal for use in food and beverage applications.

In my experience as a brewer, I have found Tri Clamp fittings to be incredibly convenient and reliable. The ability to easily disassemble and clean the fittings is particularly beneficial in the process, where sanitation is crucial. Additionally, the standardized sizing of Tri Clamp fittings allows for easy interchangeability between different components, making it simple to modify or expand a brewing system.

Understanding how Tri Clamp fittings are measured is essential for anyone working with these fittings in the food and beverage industry. By correctly measuring the outside diameter of the tubing and selecting the appropriate Tri Clamp size, you can ensure a secure and sanitary connection for your application.
