Ultra-Stream Attack Hose

WFR Ultra-Stream Attack/CAFS

Hose Construction
As Fire Hose forms the front line of attack in any fire department, it is mandatory that the design meets the requirements of today’s premier municipal firefighters. To meet these needs, WFR Wholesale Fire and Rescue Ltd is introducing Ultra-Stream. WFR has joined with Highwater Hose Inc. who has taken their third generation Matrix Encapsulated Technology and combined it with the latest techniques for obtaining high burst, minimizing kinking, abrasion damage, cutting and drag resistance. The synergized hoses so produced will have the following properties as a minimum:

Outer Jacket Properties
The outer jacket shall be woven with high tenacity spun polyester warp yarns with a minimum
diameter corresponding to 8/7 type. The jacket shall have an elastomeric impregnation to optimize
abrasion resistance and dragging coefficient. Filament Yarns that create poor handling and poor
jacket distortion characteristics are unacceptable.

Inner Hose Properties
The hose shall be constructed of top quality synthetic yarns woven into an optimized web and
embedded in a matrix of nitrile rubber, to produce high strength and low friction loss. To ensure
complete conformance, the resultant hose must meet the following minimum requirements or it will
be unacceptable.

(Hose shall be evaluated in accordance with the principles and practices listed in the National
Fire Protection Association Standard 1961 (2002 edition) and related standards.)

Ultimate Tensile Strength
Tensile strength of the vulcanized rubber compound used in the hose shall not be less than 1750
psig.

Ultimate Elongation
Ultimate elongation of the vulcanized rubber compound shall be not less than 450%.

Permanent Elongation
Permanent elongation of the vulcanized rubber compound shall be less than 22%.

Adhesion
The adhesion between samples of the reinforcement web and either the liner or the cover shall
exceed NFPA 1961 requirements. The sample width shall be 1 1/2" as called out in the standard.

Accelerated Aging Properties
When subjected to hot air oven aging at 158°F for 96 hours, the tensile strength and ultimate
elongation shall be at least 75% of the original values.

Ozone Resistance
When evaluated in accordance with standards ASTM D 1149 and ASTM D518, procedure B, 70
hours at 118'F, 100pphm of ozone, the cover or liner shall show no visible signs of cracking.

Synergized Hose Properties
Heat Resistance
When subjected to an internal static water pressure of 100 psi, the hose shall withstand a surface
temperature of 1000°F for at least 50 seconds without bursting.

Cold Resistance
Hose shall be capable of practical use down to -35°F

Abrasion Resistance
When subjected to the abrasion test listed in the Underwriters Laboratories Standard UL19, the hose
shall withstand at least 3,000 cycles without compromising the hoses ability to be used as a primary
attack hose as defined in NFPA Standard 1961 (2002).

Chemical Resistance
Contamination by most chemical substances, oils, greases, fire-fighting foam concentrates,
hydrocarbons, and exposure to sea water shall have no effect on the short or long-term performance
of the hose. A copy of the chemical resistance chart for the hose shall be provided on request by
the manufacturer.

Water Absorption
When tested against the procedure listed in MIL STD 24606 the maximum water absorbance shall
be less than 3 lbs in a 50 foot length.

Maintenance
Hose shall not support mold or mildew growth.

Burst, Hydrostatic and Physical Data
Synergized hose shall comply with the requirements listed in the tables below and the requirements of The National Fire Protection Association Standard 1961, latest edition.
