Compact SpiralTM Bend Radius
Not only is it 1/2 the bend radius, but it takes
1/3 less effort to bend.
Inner beauty
The inner tube of a hose is
offered in several different
rubber compounds. Each rubber
compound can react differently to
the media being conveyed. The
inner tube must also resist effects
of high or low temperatures
and environmental elements.

popular rubber compounds used
for hose inner tubes:
Strong like spiral
bends like braided
Looking for fexible hose that can
be routed in tight spaces?
Parker has a full line of hoses
designed for one-half SAE bend
radius at full SAE pressure. These
hoses plumb and bend tighter
than other SAE 100R1, 100R2,
100R4, 100R12 and 100R13
type hoses, reducing hose length
requirements by up to 47%. The
tighter bend radius means fewer
bent tube fttings, and longer life
in applications where machinery
movement causes hoses to bend
sharply. It also means reduced
inventory requirements for you.
Compact Spiral Hose has
half the bend radius of its SAE
counterpart and a signifcantly
smaller bend radius than
corresponding-size Parker
conventional spiral hose.
