Crimp sleeves (ferrules) for permanently swaging fittings onto hoses - the standard attachment method for hydraulic and many industrial hose assemblies, compressed with a crimping machine to defined dimensions. Correct sleeve-fitting-hose matching and crimp diameter are safety-critical. Note that crimped ferrules must never be used on steam hoses - bolted safety clamps only.
