How to Size a Tri-Clover/Tri-Clamp Fitting.
Have you ever wondered how to choose the correct Tri-Clamp size? Or how to measure an existing Tri-Clamp fitting?
The sizing is based on the outside diameter (OD) of the tube, not on the outside diameter (OD) of the flange.
For example:
- If your tube OD measurement is 2 inches, then your Tri-Clamp size is 2”.
- If your existing Tri-Clamp fitting’s flange measures approximately 2.5 inches OD (2.516”), then your Tri-Clamp size is 2”.
Consult the chart below for corresponding Size / Tube OD and Flange OD measurements.
Note:
- Sizes ½” and ¾” have the same flange OD of approximately 1 inch (0.984”).
- Sizes 1” and 1-1/2” have the same flange OD of approximately 2 inches (1.984”).
