Eight sided forged ferrule staking crimped fitting and method of manufacture thereof

Abstract

Methods of making hose fittings include providing a stem having a fluid conduit, a first end, a second end with a raised shoulder, and a crimp region disposed between the first end and the second end.A swivel tube nut is placed over the stem, and the swivel tube nut is retained on the stem by the raised shoulder. A ferrule is thereafter placed over the first end of the stem, and the ferrule comprises a partially or fully formed octagonal wrench surface, formed prior to. The ferrule is then crimped, at the octagonal wrench surface, onto the crimp region of the stem.

Description

technical field [0001] The present disclosure relates generally to hydraulic hose fittings, and methods of making such fittings, and more particularly to octagonal shapes on the exterior of the ferrule of the fitting. Background technique [0002] This section provides background information to facilitate a better understanding of various aspects of the disclosure. It should be understood that the statements in this section of this document are to be read in this light and are not admissions as prior art. [0003] Use hose fittings to connect fluid lines or hoses to various types of industrial equipment and machinery via equipment connection ports or manifolds. Hose fittings generally have two ends: one end generally defines a hose connection end, and the other end generally defines an equipment connection end. In one type of hose fitting, a rod is provided having a first end (equipment connection end) and a second end (hose connection end), wherein the second end includes...
