The life of the combination tube-hose assembly is often
limited to the service life of the hose alone. A replacement
assembly may not be available, since equipment dealers are
unable to stock all of the many odd tube configurations.
Parker Ferrul-Fix hose end fitting now makes it possible to
salvage the bent tube section of the original assembly for replace-
ment. Most importantly, it gets you back into operation FAST!
Ferrul-Fix Installation Instructions
Fast, on-the-job repair for ruptured bent tube hose assemblies
and power steering lines.

3-
Piece Design – Body, nut, ferrule. Wedging action of
ferrule, when drawn down by nut, forms seal between
body and ferrule, while cutting edge of ferrule bites into
tube wall forming another positive seal.
ƒ
ƒ
Visible Bite – Extent of bite at cutting edge of ferrule is
completely visible when fitting is disassembled, an
important safety feature. Self-centering action assures
an even bite around circumference of tube.

Parkerized Finish – Ferrul-Fix fittings have the
Parkerized black finish, providing built-in torque in
make-up.
