Size Identification:
The size of the tri-clamp is identified by the diameter of the tube it exists on, not the measurement on the face of the Tri-Clamp.
The below chart can be used to cross-reference the Line/Clamp size, the outer-diameter of face of the clamp, and the inner diameter.
0.5" and 0.75" Use the exact same clamp, but each has their own ferrule size.
1" and 1.5" Use the exact same clamp, but each has their own ferrule size.
