Carry-Lite® Specifications
Hose manufactured to this specification shall be of
superior quality and workmanship. This heavy-duty double jacket fire hose
shall be designed to withstand the rough usage of front line fire fighting.
Construction & Features
- The hose shall be of double jacket construction.
- Both inner and outer jackets shall be made with high tenacity
filament polyester yarn in both the warp and weft directions, to provide
maximum strength and very snag resistant.
- The hose outer jacket shall have a minimum filler yarns of 10.0 per
inch (394 per Meter)
- The hose shall be available in any of eight colors listed with our
Permatek treatment, upon request.
- The hose shall be resistant to most chemicals and petrol products,
rot & mildew, hydrolysis, and resist deterioration due to exposure to
UV-rays and ozone
- The hose must be of sufficient body and weight to meet the demands
of heavy-duty fire fighting.
Performance
- The hose, in all sizes, shall have minimum service, test, and burst
pressures as specified in the Technical Chart. Hoses which do not meet
these minimum pressures, shall not be considered as meeting this
specification.
- The hose shall have a maximum flow with minimum friction loss.
- The hose jacket shall be highly abrasion resistant, highly flexible,
and very snag resistant.
- There shall, be no defects, dirt, knots, lumps or other
irregularities affecting the performance of the hose.
- The hose must resist kinking and remain flexible to -65°F (-55°C).
- The hose shall not rise up from the test surface.
- The hose must resist kinking.
Lining
- The hose lining shall have excellent resistance to most chemicals,
petrol products, ozone and U.V.
- The hose lining shall be capable of being approved for potable
water, when so ordered.
- The thermoplastic lining material used for this specification
shall have a flawless record in the fire hose industry.
- Both the inner and exterior jackets shall be lined by the
patented Mertex® method without the use of adhesives or backing
material, to lock the fibers in place. The lining material in its
molten state shall fill the corrugations of the weave fusing to
every warp and filler thread and provide a very smooth and low
friction waterway. No adhesive or backing material shall be used to
bond the lining and it shall yield maximum flow with minimum
friction loss. An inner hose manufactured by inverting an exterior
coated hose shall not be considered as meeting this specification.
Hose manufactured with the use of adhesives or backing for bonding
the liner, or hose made with rubber liners shall not be considered
as meeting this specification.
Treatment
- When requested, the exterior jacket shall be Permatek® treated
for greater abrasion resistance, improved visibility & reduced
moisture pick-up.
Standards
- Fire hose manufactured to this specification shall meet & exceed
all performance requirements of NFPA 1961, Underwriter's
Laboratories & Factory Mutual.
