Abstract
An end fitting for rubber steam hoses with metal liners of interlocking construction comprises a stem that has zig-zag serrations formed on an intermediate portion of its outer surface for contacting and retaining the inside of a rubber hose, and has rib-type right hand spirals formed on an inner end portion of its outer surface so that a metal liner of interlocking construction is adapted to be screwed onto the spirals for retention of the metal liner from being pulled off the ste. on the stem and preventing the metal liner from being pulled off the stem. A clamp is provided that clamps the rubber hose against the zig-zag serrations to seal the end fitting against the escape of steam, and clamps the rubber hose against the metal liner and the metal liner against the spirals and the inner end portion of the stem outer surface to provide added retention of the metal liner from being pulled off the stem. A portion of the metal liner is always between the stem and the clamp to provide this extra retention and safety against the metal liner being pulled off the stem.
