Key Fire - 3" x 50' Magnum Hose Nylon 6.6 Spec

Key Fire Hose Nylon 6.6 Spec, 3” x 50’ Double Jacket Attack Hose 800# Test with 2.5” NST Aluminum Couplings (Stenciled OCFA) Cant be Blacked out upon request

Jacket Construction

Double jacket hose, tightly woven from entangled filament Nylon 6.6 yarn in both the inner and outer jackets and are highly abrasion resistant. The filler yarns of both the inner and outer jackets are high tenacity filament polyester for increased tensile strength and Durability. The hose is resistant to most chemicals and petrol products, and resist deterioration due to exposure to UV rays and ozone. It will not be affected by rot or mildew. Hose is of sufficient body and weight to meet the demands of heavy-duty fire fighting usage.

Abrasion Impregnation

Hose has special “Key-Lok” polymer impregnation for added abrasion resistance and ease in identification purposes. Impregnated hose meets the requirements of MIL-H-24606B for abrasion resistance. The standard color is high visibility NFPA Yellow

Lining

The rubber lining is a single-ply extruded tube of synthetic EPDM compounded to resist ozone. The finished form is free of pits or other imperfections and have a smooth finish for better flow characteristics. With no reclaimed rubber used. Plastic tubes that sacrifice durability of the hose life for the sake of weight are not acceptable and not used.

Tensile Strength & Ultimate Elongation:  meets the standards of Underwriters Laboratories, Inc. as well as all other properties of UL-19 for rubber-lined hoses. A valid U.S. Underwriters inspection procedure shall be in force.

Standards

Fire hose manufactured to this specification shall meet and exceed all performance requirements of NFPA 1961, Underwriters Laboratories and MIL-H-24606B.

Couplings

Lightweight aluminum threaded couplings with NST threads.

Finished Hose

The service test pressure of this hose is made with specification to be 400 PSI. The proof test pressure shall be 800 PSI, and the burst test pressure of a 3ft. sample shall be at least 1200 PSI. At 600 PSI pressure, a 50 ft. hose shall not elongate more than 48 inches. The twist of the hose will not exceed 2 right hand turns per 50 ft. nor shall it rise up from the test surface. The hose must resist kinking and be flexible at temperatures as low as 65°F.
