The One-Ear Clamp Kit contains a selection of W4 stainless steel one-ear stepless clamps in multiple sizes, together with a swaging pincer tool for installation. A complete solution for anyone fitting or replacing crimp-style hose clamps across a range of hose diameters — suitable for automotive cooling and heating systems, caravan and marine freshwater plumbing, fuel lines, and other applications where a low-profile, single-use crimp clamp is preferred over an adjustable worm drive.

One-ear stepless clamps (Oetiker-style) crimp to a fixed diameter and cannot be loosened or re-used — once the ear is swaged, the connection is permanent. This makes them ideal for factory-style installations and OEM replacements where tamper-evidence and a clean finish matter. The W4 (304SS) grade provides good corrosion resistance for automotive, marine freshwater, and outdoor applications.

For bulk packs of clamps only (without the tool), see the One-Ear Stepless Clamps 100-pack listed separately.
