Extruded thru-the weave nitrile rubber attack hose
SUMMARY:
Hose shall be manufactured in the United States to NFPA 1960 and ISO 9001:2015 quality management system standards and craftsmanship. Hose must meet or exceed NFPA testing requirements and be classified as Type 3 in accordance with UL-19 standards. The hose shall be free from defects in materials and workmanship.
MANUFACTURER:
The hose must be domestically sourced, woven, extruded, assembled, coupled, and tested in an ISO 9001:2015 certified facility in the United States, which shall constitute the product’s country of origin.
JACKET:
The reinforcement jacket must be woven with nylon fibers in a circular twill weave configuration. The outside surface of the hose shall have raised ribs running the entire length of the hose for improved abrasion resistance.
LINING:
The liner (waterway) must be a nitrile rubber extruded thru-the-weave. The nitrile rubber must completely encapsulate all the yarns and fibers on both sides of the reinforcement jacket and penetrate through the jacket. No rubber applied by a hot melt process into or onto the inner liner surface of the reinforcement fabric will be permitted, nor will the use of an adhesive or backing to secure a tube lining be permitted. The liner must be guaranteed not to delaminate for the life of the hose and manufactured in the United States.
TEMPERATURE FLEXIBILITY:
The hose must remain flexible at temperatures -40° F to 200° F (-40°C to 93°C).
HIGH-RISE HOSE:
The hose must meet high-rise firefighting requirements.
WEIGHT:
Hose must be measured dry coupled 50’ lengths. Weight must not exceed:
1” - 7 LBS
1-½" - 11 LBS
1-3/4” - 12 LBS
2” - 15 LBS
2-½" - 22 LBS
2-¾" - 23 LBS
SERVICE, PROOF, BURST PRESSURES:
1”, 1-½", 1-¾", 2”, and 2-½" hose must meet the following pressures; service (300 psi), proof (600 psi), and burst (900 psi). 3” hose must meet the following pressures; service (250 psi), proof (500 psi), and burst (750 psi).
FLOW & FRICTION LOSS:
When requested, friction loss test results shall be provided to the customer.
KINK RESISTANCE:
Hose must meet doorway kink resistance test at 50 psi, with the following specifications based on size:
1-3/4” - 24” bend radius.
2” - 24” bend radius.
2-½" - 30” bend radius.
ABRASIAN RESISTANCE:
The hose must withstand a minimum of 4,300+ abrasion cycles (Taber H-22 wheel) without jacket damage.
STANDARDS:
The hose must meet or exceed all performance requirements of NFPA 1960 (1961). The hose must be classified as Type 3 in accordance with UL-19, latest revision dated February 5, 2025.
QUALITY ASSURANCE PROVISIONS:
Hose manufacturer must maintain a current ISO 9001:2015 certified Quality Management System, covering the entire manufacturing process—from design and raw material procurement to weaving, extrusion, assembly, testing, and delivery.
HYDROSTATIC TESTING:
Each coupled hose must undergo hydrostatic proof testing by the manufacturer and meet NFPA 1961 (latest edition) standards. Test certification must be provided with each length.
IDENTIFICATION AND MARKING:
Each hose must have a unique barcode on the coupling per NFPA 1962, linking to manufacturing and test records. The manufacturer must maintain a customer-accessible electronic database for the hose’s service life. Hoses must also be marked with the manufacturer’s name, date, origin, and “Service Test to ___ PSI per NFPA requirements.”
COUPLINGS:
All coupled hose must be assembled with couplings sourced in the United States and must meet or exceed NFPA 1963 - latest edition.
WARRANTY:
The fire hose must have a ten-year warranty against manufacturing defects, and a lifetime warranty against liner delamination.
