Polyvinyl Chloride Flexible Hose

New concept in flexible hose with a combination of
properties never before attained in hose construction.

FLEXIBILITY
Cobovac-W hose can be installed with tight bends without restricting the inside diameter.  The patented over and under vinyl construction provides extreme flexibility with proven vinyl toughness.
OPERATING TEMPERATURE
Cobovac-W vinyl hose performs within a wide range, from - 20F to +170F.  Specific upper and lower limits depend upon application specifics.
CHEMICAL RESISTANCE
Cobovac-W vinyl hose is an industrial champion for handling corrosive chemicals.  It safely conveys all acids, alkalies, gases and fumes compatible with vinyl.
SMOOTH BORE
Cobovac-W vinyl hose features an unique patented construction that results in a smooth bore for moving all materials.  There is no exposed coil to interfere with the flow.
NON-FLAMMABLE VINYL
The vinyl material in Cobovac-W hose is self-extinguishing.  This makes it ideally suited for hazardous applications where flammability is a problem.
LONG LENGTHS
The exclusive Cobovac-W manufacturing process permits supplying this hose in continuous lengths within the limitations imposed by handling, packing and shipping.
OUTDOOR EXPOSURE
Thousands of hours of continuous exposure to sunlight will not crack or peel the vinyl material.  Cobovac-W vinyl hose has long service life when used indoors or outdoors.
FINE APPEARANCE
Modern design - uniform construction - smooth plastic material and high gloss gray color gives Cobovac-W hose unsurpassed appearance.  Gray is the standard color but any color is available on special order.
