Notes
- Clamp face one end, a three-ridge hose barb the other; ridges reach the published barb OD (hose ID + 0.040 in) and ramp back to the hose ID. Overall length matches the published A where the barb fits in it; otherwise the actual length is in each file note.
- ½–¾ in clamp means the 25 mm mini flange; 1–1½ in means the 50.5 mm flange.
- Every clamp face is the ISO 2852 profile used across this site: 2.85 mm rim, flat face with the gasket groove (K 1.6 deep, R3 1.2 bottom, 23° walls, P2 0.8 edges) on C2, 20° back cone.
