There is no universal hose that works for all
products, in all applications, for all situations.
The hose you select depends on the type of service
it will perform, and the products it is expected
to transport.
Before selecting a hose, there are several factors
to consider, including whether the hose will be
subject to high or low pressures; performing
suction or discharge functions; subject to
extreme heat or cold; subject to rolling, flexing,
or dragging; or exposed to corrosive materials.
Remembering these factors and others will help
you select hoses, clamps, and fittings that are
designed for specific applications, and help you
separate the hoses that do work from those that don’t.
For the purposes of this publication, we have
developed 13 questions you should always answer
when you select a hose. By answering these ques-
tions, your retailer will be able to help you select
hoses, clamps, and fittings that are designed for
specific applications, will best meet your needs,
and provide good value over time.

What
Materials
Will
the Hose Carry?
The materials used to make hoses are just as
diverse as the products that can be pumped
through them. Hoses for application equipment
are designed and built to withstand the
detrimental effects of the fertilizers, fuels,
pesticides, or hydraulic fluids they carry.
If you select a hose that is incompatible with
the material it will carry, the hose lining will
become brittle, stiff, or soft, and will deteriorate.
This can lead to weak areas in hoses that will be
unable to withstand pressure surges and will fail.
Hoses are frequently labeled and designed for specific
uses and for particular chemicals or environments.
