rigidity that ensures that the hose stays true to your
lines and a superior flexibility to allow for unparalleled
alignment compensation.
In addition to installation ease, Parker preformed
products increase productivity thanks to dramatic
reductions in weight, leak paths and the number of
components. They also are highly cost effective for the
manufacturer. With excellent shape retention, Parker
products can be easily coiled and packed in standard
boxes, saving on shipping costs and inventory space.
Extremely Lightweight
Compared to rubber equivalents, Parflex products
are lighter in weight due to their fiber reinforcements.
In fact, a Parflex hose can weigh more than 70% less
than a comparable rubber hose assembly. As a result
of this greater strength-to-weight ratio, thermoplastics
are easier to work with. Operator handling becomes
less fatiguing and it is quicker and easier to route hoses
onto equipment.
Economical Small Bore
Prior to thermoplastics, system designers had to use
hoses that wereoversized for certain applications.More
economical, small-bore rubber hose was simply not
available in sizes smaller than 1/4” for applications with
flows less than 3 gallons per minute. The use of over-
sized hoses resulted in substantial waste in systems;
costing more, reducing response times and increasing
installation times.
Today, system designers have a wealth of options to
the 1/4” rubber hose. In fact, thermoplastic hose manu-
facturers have established full lines of hose for every
application. With sizes that include
1/4”
,
3/16”
,
1/8”
,
and
3/32”
,
Parflex compact designs allow tighter bend
radius characteristics, work well in smaller enveloped
areas and give excellent fluid compatibility and higher
abrasion resistance.
The Parflex Polyurethane Air Hose (Ultra-Lite
Superbraid) weighs 29% less than equivalent
thermoplastic products and 63% less
than equivalent rubber air hoses.
