What the Minimum Bore Tells You
The minimum bore is the narrowest inside diameter through the joint, so it limits how wide a tube, rod or thermometer stem can be and still pass through. The 13 and 14 threads share a 7.5 mm bore, while the 32 thread opens to 26.0 mm. Compare this figure with the outside diameter of whatever must go through before choosing a size.
