GUARD, COVERS, AND DOCUMENTATION
Metal hose assemblies often require special accessories or components to ensure long service life in
severe applications, or to make the assemblies easier to use. There are many accessories that may be
specifed, including:
• Guards, made from metal and other materials, can be provided to protect an assembly from
overbending, abrasion, impact, and thermal damage.
• Jacket and tracer hoses are used with corrugated hose assemblies to keep certain media at
elevated or reduced temperatures so that it can be conveyed easily.
• A sacrifcial bronze braid can be inserted between the hose and the stainless steel braid to
improve cycle life.
One or several accessories can be easily combined with an assembly to more effciently transport
media, protect the assembly, or both.
This is not an exhaustive list of possible accessories, please consult Hose Master’s Inside Sales
Department for details.
Spring Guard
When there is potential for damaging an assembly in service, a
guard can be easily installed during fabrication. This type of guard
consists of a metal spring that is attached behind the ftting. The
style of guard can be tailored to meet the specifc application and
the type of hose.
Protective Cover
If the potential for impact or high-temperature damage is not severe,
or if the additional weight and bulk of a full-metal guard is
unacceptable, rubber or plastic scuff guards can be installed to
protect the corrugated hose and braid.
Insulating Jacket
If the corrugated hose is to convey high-temperature media, and
there is a potential for skin contact, an insulated protective jacket
is available. The jacket consists of braided fberglass insulation,
covered and impregnated with silicone rubber that is then installed
over the corrugated hose and sealed. The jacket can also be used
to insulate the corrugated assembly and either prevent ambient
heat from being conveyed to the media or to reduce heat loss.
Tagging
A variety of tags and identifcations can be affxed to
assemblies. These include cardboard, plastic, and metal tags.
Serial numbers, application information, assembly performance
capabilities, and other customer-specifc information can be
provided either on tags or permanently engraved onto one or both
braid collars.
Certifications
Standard written certifcations for materials or inspections can
be supplied for corrugated hose or assemblies. Certifcations of
conformance to specifc customer requirements, such as military
certifcations, PMI (Positive Material Identifcation), and PED are also
available upon request.
