Key Fire Hose PRO-FLOW HP Hi-Pressure Rubber Covered Attack Hose with STORZ Couplings
Meet the Key Fire Hose PRO-FLOW HP Hi-Pressure Rubber-Covered Attack Hose with STORZ Couplings, a high pressure, high visibility, large diameter attack/supply hose with a 300-psi service test pressure.
The Key Fire Hose PRO-FLOW HP Hi-Pressure Rubber-Covered Attack Hose with STORZ Couplings is designed for maximum performance and durability. Its nitrile/PVC through-the-weave design is heat- and chemical-resistant, allowing the hose to expand under pressure, which reduces friction loss and improves water flow.
The thin rib rubber outer cover enhances resistance to impact, punctures, and abrasion, making it a reliable and low-maintenance attack fire hose. With no drying required, this NFPA-compliant and UL-listed hose is ideal for busy municipal fire departments handling high-pressure situations.
STORZ coupling size will match the hose diameter. Ex. 4" STORZ equals 4" hose, 5" STORZ equals 5" hose etc.
Features:
- High visibility, high pressure large diameter supply line
- Raised thin rib construction, resists cuts, punctures, impact and abrasion
- Through-the-weave design for increased durability
- Heat, chemical and ozone resistant
- 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. Pro-Flow HP features a thin rib construction to aid abrasion resistance. Pro-Flow HP meets or exceeds requirements of NFPA 1961. Pro-Flow HP shall carry a 10-year written warranty against defects in materials and workmanship. Lengths available up to 100'.
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 Pro-Flow HP 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 with 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:
Pro-Flow HP coupling options are as required by purchaser, expansion ring threaded, Storz clamp ring, etc.
