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”).

| Tri-Clamp Size / Tube OD | Tri-Clamp Flange OD |
|---|---|
| 1/2″ & 3/4″ | 0.984″ |
| 1″ & 1-1/2″ | 1.984″ |
| 2″ | 2.516″ |
| 2.5″ | 3.047″ |
| 3″ | 3.579″ |
| 4″ | 4.682″ |
| 6” | 6.570” |
| 8” | 8.602” |
| 10” | 10.570” |
| 12” | 12.570” |
