Are 1 and 1.5 tri-clamp the same?

Answered by James Kissner

Tri Clamp sizes refer to the outer diameter (OD) of the tube that the fitting is designed to connect. In the case of 1″ and 1.5″ Tri Clamp fittings, they have different tube ODs, meaning they are not the same.

A 1″ Tri Clamp fitting is designed to connect to a tube with a 1″ OD, while a 1.5″ Tri Clamp fitting is designed to connect to a tube with a 1.5″ OD. This size difference is important because it determines the compatibility of the fitting with the tubing or piping system you are working with.

The flange OD of both the 1″ and 1.5″ Tri Clamp fittings is the same, measuring approximately 1.984″. This means that the fittings can be secured using the same size clamp, which has a 1.5″ clamp size.

To further clarify, let’s consider an example. If you have a system with a 1″ tube OD, you would use a 1″ Tri Clamp fitting to connect it. On the other hand, if you have a system with a 1.5″ tube OD, you would use a 1.5″ Tri Clamp fitting. In both cases, you would use a 1.5″ clamp to secure the fitting.

It’s important to note that Tri Clamp fittings are commonly used in sanitary applications where cleanliness and ease of disassembly are crucial. The clamp design allows for quick and secure connections, making them popular in industries such as food and beverage, pharmaceuticals, and biotechnology.

When selecting Tri Clamp fittings, it’s essential to ensure that the tube OD matches the fitting’s size to achieve a proper connection. Using the wrong size fitting can result in leaks or other issues that may compromise the integrity of the system.

1″ and 1.5″ Tri Clamp fittings are not the same. They have different tube ODs, but they share the same flange OD and use a 1.5″ clamp for securing. It’s crucial to select the correct Tri Clamp size to ensure a proper and secure connection in your sanitary system.
