Quality: The fire hose assembly supplied under this specification
shall be constructed with superior quality materials.
NFPA 1961 standards shall be observed in production of the
assembly, in order to ensure its quality and durability.
Warranty: Pro-Flow hose shall carry a 5 year warranty
against defects in material and workmanship. Barring any
mistreatment or accidental damage the warranted hose
will be replaced at no charge.
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 single homogeneous construction without
the use of glues or adhesives of any type.
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 vulcanized rubber compound
which has been subjected to the action of oxygen at 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.
Hose shall withstand 20,000 cycles on the Taber Abrasion
Machine (H-22 Wheel: 1 kg). Key Fire Hose Corporation on
request will supply written warranties that PRO-FLOW hose
meets a minimum 20,000 cycles. Other abrasion test results
(UL, DIN, etc.) can be supplied on request of purchaser.
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 subjected to the hydrostatic acceptance test
Hose shall show no visible signs of cracking to the lining
or cover when tested in accordance to ASTM D518
Procedure B (100pphm/118°F/70 hours).
Exposure to sea water and contamination by most
chemical substances, hydrocarbons, oils, alkalis, acids
and greases must have no effect on the short or long
term performance of the hose. A chemical resistance
chart is available and Key Fire Hose will supply specific
chemical resistance data on request of purchaser for
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.
** Customers are advised special diameters or construction characteristics may be
produced by special request. For more information please contact your JGB Sales Representative.
