The 5'11" (1.8m) Varioflex Crushproof hose is produced without the overlapping profile bonded together that is characteristic of most crushproof hoses. It leads to a uniform wall, resulting in a better performing hose when subjected to the flexing and stresses encountered in various applications. The Varioflex process also eliminates potential unraveling and stress points which can result in premature hose failure. The 42638 specifically fits Miele straight air non-electric hose assemblies. This version fits 1.375" (35mm) connections and is silver in color.
