S
SAE: Society of Automotive
Engineers.
shank: that portion of a fitting,
which is inserted into the bore of
a hose.
skive: the removal of a short length
of cover and/or tube to permit the
attachment of a fitting directly over
the hose reinforcement.
sleeve: a metal cylinder, which
is not physically attached to the
fitting, for the purpose of forcing
the hose into the serrations of the
fitting.
smooth bore: a term used to
describe the type of innercore in
a hose.
specification: a document setting
forth pertinent details of a product.
spiral: a method of applying
reinforcement in which there is
not interlacing between individual
strands of the reinforcement.
spring guard: a helically wound
component applied internally or
externally to a hose assembly, used
for strain relief, abrasion resistance,
collapse resistance.
standard: a document, or an
object for physical comparison, for
defining product characteristics,
products, or processes, prepared
by a consensus of a properly
constituted group of those
substantially affected and having
the qualifications to prepare the
standard for use.
static wire: wire incorporated in a
hose to conduct static electricity.
stem: see nipple.
Sub-Zero: a low temperature
resistant hose that is a registered
trademark of Danfoss Corporation.
surge (spike): a rapid and transient
rise in pressure.
T
Thick-Flange: a hose end fitting
that is trademarked by Danfoss
Corporation.
tube: the innermost continuous allrubber or plastic element of a hose.
tube fitting: see fitting/coupling—
tube.
tubing: a non-reinforced,
homogeneous conduit, generally of
circular cross-section.
V
vacuum resistance: the measure
of a hoses ability to resist negative
gauge pressure.
vibration: amplitude motion
occurring at a given frequency.
viscosity: the resistance of a
material to flow.
vulcanization: a process during
which a rubber compound, through
a change in its chemical structure,
improves or extends elastic
properties over a greater range of
temperature.
W
weathering: the surface
deterioration of a hose cover during
outdoor exposure, as shown by
checking, cracking, crazing and
chalking.
wire reinforced: a hose containing
wires to give added strength,
increased dimensional stability and
crush resistance. See reinforcement.
working temperature: the
temperature range of the
application; may include the
temperature of the fluid conveyed
or the environmental conditions the
assembly is exposed to in use.
WP: working pressure.
swelling: an increase in volume
or linear dimension of a specimen
immersed in liquid or exposed to
a vapor.
