a Scope
Quality: The fire hose assembly supplied under this spec-
ification 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.
a Hose Construction
Hose shall be made from 100 percent high tenacity syn-
thetic yarn, circularly woven and completely protected
and locked-in by tough highly resistant synthetic nitrile
rubber, forming a single homogeneous construction with-
out the use of glues or adhesives of any type.
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 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 per-
cent of its originally stated properties.

RC17-500 13/4” 250psi 500psi 800psi
RC20-500 2” 250psi 500psi 750psi
RC25-500 21/2” 250psi 500psi 750psi
RC30-500 3” 250psi 500psi 750psi
Note: Per NFPA, attack hose shall have a minimum design service
pressure of 300 psi. See our Dura-Flow line for this type of hose.
a Abrasion Resistance
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.
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 reinforce-
ment when subjected to the hydrostatic acceptance test
stated above.
a Ozone Resistance
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).
a Chemical Resistance
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
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
Weight per Coil Size-Coupled
Part # Diameter Length (Coupled) per 50’ Lengths
RC15-500 11/2” 16 lbs 151/2 in.
RC17-500 13/4” 17 lbs 16 in.
RC20-500 2” 19 lbs 17 in.
RC25-500 21/2” 26 lbs 17 in.
RC30-500 3” 32 lbs 18 in.
a Color
The stock colors are HI-VISIBILITY yellow or red.
Other colors available upon request.
a Couplings
As required by purchaser, expansion ring threaded,
STORZ clamp ring, etc.
Key reserves the right to modify any specification with-
out prior notice to meet or exceed changing standards.
Customers are advised that special diameters or con-
struction characteristics can be produced on special
