Tri-clamp × hose barb adapters (14MPHR style): ½ to 4 in clamp, ¼ to 4 in hose — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/tri-clamp-hose-barb-adapters/ (CC BY 4.0) Basis: Face-to-end A per Steel & O'Brien and Dixon 14MPHR (they agree); barb OD B = hose ID + 0.040 in (Dixon); barb ridges (three, sawtooth) are a Xem Studio profile on those two numbers Catalog version: 2026-10-20 Sizes: see table below - 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.
