Key Fire Hose DURA-FLOW Rubber Covered Through-the-Weave Thick-Ribbed Attack Hose with Aluminum Couplings

Key Fire Hose DURA-FLOW Rubber Covered Through-the-Weave Thick-Ribbed Attack Hose with Aluminum Couplings

**If you do not see a spec listed, please contact us to order**

The lightweight, small diameter, rubber covered attack hose that packs a big punch. The heat and chemical resistant, nitrile/PVC through-the-weave design provides peak performance and maximum flow. With a test pressure of 600 psi, Dura‑Flow clearly outperforms conventional rubber covered attack lines.

A rugged, thick ribbed outer jacket construction makes the hose highly resistant to kink, impact, punctures, cuts and abrasion.

Ozone resistant, maintenance-free and no drying required, make Dura-Flow a reliable weapon in a firefighter’s arsenal. NFPA compliant and UL listed.

Features:

• Lightweight, greater flexibility and virtually kink-free
• Raised thick rib construction, resists cuts, punctures, impact and abrasion
• Through-the-weave design for increased durability
• Heat, chemical and ozone resistant
• Easy to clean, easy to pack
• 10-year warranty

Hose Construction:

Hose shall be made from 100% high tenacity synthetic polyester yarn, circularly woven and completely protected by a through-the-weave extruded PVC/Nitrile rubber, forming a single homogeneous construction without the use of glues or adhesives of any type. Dura-Flow features a raised thick rib construction to aid abrasion resistance. Dura-Flow meets or exceeds all requirements of NFPA 1961 for attack hose. Dura-Flow shall carry a 10-year written warranty against defects in materials and workmanship

Lining Properties:

Ultimate Tensile Strength - Tensile strength of the lining and cover shall not
be less than 1200 psi.

Ultimate Elongation - 400% 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 (±10 psi) and a temperature of 158 °F (±18 °F) for a period
of 96 hours shall retain 60% of its originally stated properties.

Abrasion Resistance:
Hose shall withstand 10,000 cycles on the Taber Abrasion Machine (H-22 Wheel: 0.5 kg), without exposing the liner. Key Hose, on request, will supply written warranties that Dura-Flow hose meets a minimum 10,000 cycles. Other abrasion test results (UL, DIN, etc.) can be supplied on request of purchaser. 

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 flexibility test: a 50' 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. 

Ozone Resistance:

Hose shall show no visible signs of cracking to the lining or cover when tested in accordance to ASTM D518 Procedure B (100 pphm / 118 °F / 70 hours).

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 Hose will supply specific chemical resistance data on request of purchaser for unique applications.

Couplings:

Dura-Flow coupling options are as required by purchaser, expansion ring threaded, Storz clamp ring, etc. Barcode recess available at additional charge.

Performance:

The minimum burst test pressure, when tested in accordance to NFPA 1961, on all Dura-Flow diameters shall be 900 psi / 62 bar. Service test pressures stenciled on the hose shall be in accordance with current minimum requirements of NFPA 1962. *A valid UL/ULC Underwriters 500 psi / 34 bar listing shall be in force. Lengths available up to 300'.
