About this file
This is a technical specification document for Firebreak II self-protecting synthetic forestry hose for the State of Maine. The specification outlines detailed requirements for fire hose products designed for wildland, urban interface, and structural fire suppression applications. The hose must be manufactured by Mercedes Textiles Limited or meet equivalent performance standards, with three primary size options: 1-inch (730 model), 1.5-inch (731 model), and 2.5-inch (734 model). Each size carries specific performance requirements including service pressures ranging from 300 to 600 PSIG, proof pressures from 600 to 1,000 PSIG, and burst pressures from 800 to 1,200 PSIG. The 1.5-inch hose must be capable of flowing 70 US GPM with maximum pressure loss of 10 PSIG per 100 feet.
The specification mandates superior construction quality featuring single-jacket design with high-tenacity filament polyester yarn, tight twill weave pattern with minimum 10.8 filler yarns per inch, and the patented Hydro-Wick weeping process for self-protection. The hose must be resistant to chemicals, petrol products, UV rays, ozone, rot, mildew, and hydrolysis, with flexibility maintained to -65°F. All hoses must meet or exceed NFPA 1961 standards, Underwriter's Laboratories requirements, and Factory Mutual specifications, with no defects, dirt, knots, or irregularities permitted. The lining must utilize the patented Mertex method without adhesives or backing material, providing maximum flow efficiency with minimum friction loss. ULC approval and labeling are required for the specified sizes.

Self-protecting (Percolating) All Synthetic Forestry Hose 300 PSIG / 2070 kPa Service Pressure
Superior Performance & Durability
THE # 1 CHOICE" OF THE CANADIAN FOREST FIRE AGENCIES, FEATURES OUR HYDRO-WICK® SELF
PERCOLATING PROCESS, A ULC APPROVED WEEPING HOSE!
Applications
Urban Interface, Grass Fire Kits, and Mop Up Hose Forestry Light Weight, Self-protecting Attack Hose
Wildland Brush Fire Truck Attack Hose
Uses our patented Hydro-Wick® Weeping process which weaves the yarn through the liner producing a "Wick" effect to dampen the hose jacket. This "Wick" effect results in considerable less pressure loss due to Weeping and eliminates clogging, as compared to the needle prick process used by our competitors.
Cottage & Forestry Home Values Protection Hose
Our Patented Mertex® lining process produces an amazingly thin but smooth inner waterway, yielding an extremely low friction loss for maximum flow.
Tough and ready for action but light in weight.
Resistant to most chemicals, petrol products, ozone & U.V. exposure, hydrolysis, and rot & mildew.
Will remain flexible to -65º F (-55º C).
Meets ULC requirements and can be labeled upon request in the sizes specified*.
Meets or exceeds all performance requirements of NFPA 1961, Underwriter's Laboratories & Factory Mutual.
Patented Mertex® Lining Process Welds the lining directly to the textile while the hose is being woven.
This allows the use of high strength Filament Polyester yarn to be used, due to the Mertex® process superior liner adhesion.
Locks fibers together for greater strength while still allowing for a high flexibility.
Creates a virtually inseparable bond without the use of adhesives. Huge advantage over competitors.
Yields an extremely low friction (pressure) loss because the Mertex® process fills the corrugations of the weave, which creates an amazingly thin and smooth waterway.
Mertex® lined hose produces lower elongation under pressure. This means less pull back when water is suddenly shut-off, resulting in a safer hose to work with.
Permits manufacturing to special lengths. Consult factory for details.
Patented Hydro-Wick® Weeping Process Our patented Hydro-Wick® Weeping process is achieved by weaving the yarn through the liner which produces a "Wick" effect to dampen the hose jacket.
This "Wick" effect results in considerable less pressure loss due to weeping and eliminates clogging, as compared to the needle prick process used by our competitors.
The resulting wet jacket provides excellent protection against heat, i.e., such as in forest fire applications.

Bid Specifications
Scope:
Hose manufactured to this specification shall be of superior quality in both workmanship and raw materials. Within the scope of a single jacket construction the hose shall be resistant to wear and tear. The hose shall not deteriorate from the effects of aging.
Construction and Features:
The hose shall be of single jacket construction.
The jacket shall be made with high tenacity filament polyester yarn in both the warp and weft directions, to provide maximum strength to weight ratio.
The jacket shall be woven in a tight twill weave to yield maximum abrasion resistance.
The hose outer jacket shall have a minimum filler yarns of 10.8 per inch (425 per Meter) The hose shall be resistant to most chemicals and petrol products, rot & mildew, hydrolysis, and resist deterioration due to exposure to UV-rays and ozone.
The hose shall be self-protecting by percolating just the right amount of water through the jacket for even protection along its entire length. This Weeping process shall be achieved by weaving the yarn through the liner thus producing a "Wick" effect to dampen (wet) the hose jacket.
The 1 1/2” (38 mm) hose shall be capable of flowing 70 US GPM (264 LPM) with a maximum pressure loss of 10 PSIG (69 kPa) per 100’ (30.48M). A hose with a friction loss greater than this shall not be considered as meeting this specification.
The hose must resist kinking and remain flexible to -65°F (-55°C).
The hose jacket shall be highly abrasion resistant, highly flexible, and very snag resistant.
There shall, be no defects, dirt, knots, lumps or other irregularities affecting the performance of the hose.
Technical Chart
Performance:
The hose, in all sizes, shall have minimum service, test, and burst pressures as specified in the Technical Chart. Hoses which do not meet these minimum pressures, shall not be considered as meeting this specification.
How to Specify Firebreak II®
Standards:
Fire hose manufactured to this specification shall meet & exceed all performance requirements of NFPA 1961, Underwriter's Laboratories & Factory Mutual.
Twisting and warping shall be at least 100% better than required, by the applicable NFPA standards.
The hose shall not rise up from the test surface.
Lining:
The hose lining shall have excellent resistance to most chemicals, petrol products, ozone and U.V.
The hose lining shall be capable of being approved for potable water, when so ordered.
The thermoplastic lining material used for this specification shall have a flawless record in the fire hose industry.
The hose jacket shall be lined by the patented Mertex® method without the use of adhesives or backing material, to lock the fibers in place. The lining material in its molten state shall fill the corrugations of the weave fusing to every warp and filler thread and provide a very smooth and low friction waterway. No adhesive or backing material shall be used to bond the lining and it shall yield maximum flow with minimum friction loss. An inner hose manufactured by inverting an exterior coated hose shall not be considered as meeting this specification. Hose manufactured with the use of adhesives or backing for bonding the liner, or hose made with rubber liners shall not be considered as meeting this specification.
