Square Cutting
The stripwound profile is helical. When it is cut by traditional methods, the hose
end will also be helical, creating a gap between the fitting and the end of the
hose. This gap can cause the fittings to separate from the hose during use.
Square cutting the hose ends ensures that the hose and the fitting are flush.
Interlocked metal hose is used in a variety of applications. Just as the hose, fittings, and other assembly
parts must be tailored to suit the demands of the service, so must the methods of joining these components.
Hose Master has developed specialized fabrication procedures to ensure the integrity and serviceability of
metal hose assemblies in even the most extreme applications.
Epoxy
Fittings may be attached to interlocked hose using a two-part epoxy. An
epoxied fitting-to-hose connection, made with properly prepared fittings, can be
as strong as or stronger than the hose itself at service temperatures up to
200ºF. Epoxy is recommended for packed interlocked hose to avoid damaging
the packing material. Epoxy also affords a convenient method for field
attachment of a variety of fittings to interlocked hose.
Welding/Brazing
Welding provides the strongest possible connection between the hose and
fittings. Whenever possible, the weld is made on the interior hose-to-fitting
joint, in order to provide a smooth surface over which the media flows. Welding
is generally not recommended for packed interlocked hose, as the packing may
be damaged by the high welding temperature.
ID/OD Welding
Welding the interior hose-to-fitting joint provides for a smooth transition,
preventing product from becoming damaged. Also, welding on the outside of
the hose prevents exterior contamination from entering the crevice and
provides additional strength.
FABRICATION OPTIONS

Mechanical Attachment (Tar & Asphalt)
Certain high-temperature applications, like tar and asphalt service, require a
fitting that actually threads and locks onto the hose corrugations. A high-
temperature packing is used to seal against leakage. These fittings are leak-
tight up to 500º F and are easily field attached.

Flow-Tite
The internally expanded design eliminates the need for welded or epoxied
ends, while providing a leak-free, full-flow connection. These fittings are ideal
for use with packed stripwound hose in dense-phase pneumatic conveying
systems, or whenever a smooth assembly interior is required.
