a Hose Construction
Hose shall be made from 100 percent high tenacity synthetic
yarn, circularly woven and completely protected and locked-in
by tough highly resistant synthetic nitrile rubber, forming a sin-
gle homogeneous construction without the use of glues or
adhesives of any type. Meeting all requirements of NFPA 1961.
Warranty: Hose shall carry a five year written warranty.
a Lining Properties
Ultimate Tensile Strength:
Tensile strength of the lining and cover shall not be less
than 1500 PSI.
Ultimate Elongation:
400 percent minimum.
Accelerated Aging Test:
The tensile strength and ultimate elongation of the vul-
canized rubber compound which has been subjected to
the action of oxygen of a pressure of 300 PSI (±10PSI) and
a temperature of 158°(±18°)F for a period of 96 hours
shall retain 60 percent of its originally stated properties.

a Abrasion Resistance
Hose shall withstand 30,000 cycles on the Taber Abrasion
Machine (H-22 Wheel: 1 kg). Key Fire Hose Corporation on
request will supply written warranties that DURA-FLOWhose
meets a minimum 30,000 cycles. Other abrasion test results
(UL, DIN, etc.) can be supplied on request of purchaser.
a Cold Resistance
Hose shall have a capability of use down to -35°F. Hose shall
have no apparent damage to cover, reinforcement or lining
when subjected to the following cold bending test: a 50 ft.
length of dry hose is to be firmly coiled and placed in a cold box
at -35°F for a duration of 24 hours. Immediately after removal
of the hose from the box, hose should be uncoiled and laid out
by one operator. Following this procedure, the hose shall not
leak nor show any damage to the reinforcement when sub-
jected to the hydrostatic acceptance test stated above.
a Ozone Resistance
Hose shall show no visible signs of cracking to the lin-
ing or cover when tested in accordance to ASTM D518
Procedure B (100pphm/118°F/70 hours).
a Chemical Resistance
Exposure to sea water and contamination by most chem-
ical substances, hydrocarbons, oils, alkalis, acids and
greases must have no effect on the short or long term per-
formance of the hose. A chemical resistance chart is avail-
able and Key Fire Hose will supply specific chemical resist-
ance data on request of purchaser for unique applications.
a Heat Resistance
The hose, when subjected to a static pressure of 100 PSI,
shall be capable of withstanding a surface temperature of
1200°F for a minimum of two minutes without rupture
or damage to the synthetic reinforcement.
a Hose Weight and Coil Diameters
The hose shall conform to the following average weights
and diameters
Part Weight per Coil Size - Coupled

The color shall be of HI-VISIBILITY yellow or red.
Other color available are: blue, orange and green.
a Couplings
As required by purchaser, expansion ring threaded,
STORZ clamp ring, etc.
