Types of ferrules

Ferrules for textile reinforced hose :

At the forward end of the ferrule, the recess G is designed to lock onto the collar of the hydraulic insert during swaging : the insert and the ferrule therefore become interdependent.
Moreover, the back-stop B is designed to facilitate mounting and enhance reliability of the hose which cannot hinder the positioning of the collar during swaging.
Barbs (detail C) are not very pronounced, so as not to damage either the textile structure of the hydraulic hose or its outer cover which is not skived before swaging.

Ferrules for steel-reinforced hose with internal and external skiving :

At the forward part of the ferrule, the heel T is designed to lock into the collar of the hydraulic insert during swaging in order to obtain an interdependent assembly.
The boss (detail D) is destined to be swaged directly onto the high-tensile steel spirals, which have previously been skived on the inside and outside, locking them into a female recess on the tail of the hydraulic insert.
Resistance is of high quality, assembly being metal to metal.
The barbs (detail D) are designed to ensure sealing of the inner tube through external compression on the metal spirals.
The back inner shape (detail E) of the ferrule is designed to ensure sealing between the ferrule and the outer rubber cover, in such a way as to prevent any external agent from corroding the metal reinforcement of the hose.
Swaging is considered correct when the internal bore of the hose insert has collapsed by several tenths of a millimeter according to recommendations by TECALEMIT FLEXIBLES®.

Ferrules for steel-reinforced hose without external skiving :

At the forward end of the ferrule, the recess G is designed to lock onto the collar of the hydraulic insert during swaging : the insert and the ferrule therefore become interdependent.
Moreover, the back-stop B is designed to facilitate mounting and enhance reliability of the hose which cannot hinder the positioning of the collar during swaging.
The internal barbs (Detail C) are very pronounced and sharp. During swaging, these barbs bite through the rubber outer cover and into the steel braid or spiral of the hose.
Swaging is correct when the internal bore of the hose insert has collapsed by several tenths of a millimeter accroding to recommendations by TECALEMIT FLEXIBLES®

Ferrules for steel-reinforced hose with external skiving :

At the forward end of the ferrule, the recess G is designed to lock onto the collar of the hydraulic insert during swaging : the insert and the ferrule therefore become interdependent.
Moreover, the back-stop B is designed to facilitate mounting and enhance reliability of the hose which cannot hinder the positioning of the collar during swaging.
The barbs (detail C) , of a fir-tree shape, are pronounced without being sharp.
These barbs bite into the steel braid or spiral of the hose which has been externally skived beforehand.
Swaging is considered correct when the internal bore of the hose insert has collapsed by several tenths of a millimeter according to recommendations by TECALEMIT FLEXIBLES®.
