Designed for commercial and residential fire protection systems, our Commercial-Grade Fire Fighting Pipe Clamp & Hanger Flexible Hose offers a perfect balance of safety, versatility, and cost-effectiveness. Constructed with galvanized carbon steel clamps and a high-strength NBR rubber hose, this assembly provides reliable performance in moderate-pressure firefighting applications while adhering to strict building code requirements. The lightweight design (20% lighter than industrial counterparts) simplifies installation in overhead sprinkler systems, while the corrosion-resistant coating ensures long-term durability in humid environments. The flexible hose segment supports nominal diameters from 1.5" to 4", featuring a spiral steel wire reinforcement that maintains structural integrity during high-frequency vibrations from pump operations.
Code-Compliant Safety Design: Meets UL 2112 (Fire Hose for Fixed Systems) and FM Global standards, ensuring compatibility with automatic sprinkler systems in commercial buildings. The flame-retardant NBR rubber liner resists degradation from prolonged exposure to firefighting chemicals and detergents, maintaining water purity for extended service life.
Easy Installation & Adjustability: The patent-pending quick-lock clamp mechanism reduces setup time by 50%, allowing single-person installation without specialized tools. The adjustable hanger bracket includes pre-drilled mounting holes for standard 2x4 building frames, with a 180° swivel joint that accommodates horizontal and vertical pipe alignments in tight ceiling spaces.
Vibration & Noise Control: The hose's dual-layered rubber composite absorbs low-frequency vibrations from fire pumps, minimizing noise transmission in occupied areas. The anti-rattle clamp design features rubberized gaskets that eliminate metal-to-metal contact, ideal for sensitive environments like hospitals, schools, and office complexes.
Temperature & Chemical Resistance: Rated for -20°F to 212°F (-29°C to 100°C), the hose performs reliably in both heated commercial kitchens and unheated stairwells. The galvanized steel components resist rust in high-moisture zones such as parking garages and laundry facilities.
Ideal for commercial and institutional fire safety systems, this product excels in:
High-Rise Buildings: Provides flexible connections for riser pipes in elevator shafts and mechanical rooms, adapting to building settlement movements.
Retail & Office Spaces: Ensures discreet installation in drop ceilings, with customizable hose lengths (up to 20 feet) for complex sprinkler layouts.
Educational & Healthcare Facilities: Meets strict safety codes for schools, hospitals, and nursing homes, offering low-maintenance solutions with long service intervals.
Parking Garages: Resists salt corrosion from de-icing chemicals, maintaining integrity in below-grade fire hydrant systems.
Q: Is this hose suitable for potable water systems?
A: While primarily designed for firefighting, the NBR liner is NSF-61 compliant for incidental contact with drinking water, making it suitable for combined sprinkler-potable systems.
Q: Can it be used in exposed outdoor locations?
A: Yes, the UV-stabilized hose cover and galvanized steel components provide 10+ years of outdoor service when installed with protective UV sleeves (sold separately).
Q: What is the minimum bend radius?
A: The hose allows a minimum bend radius of 4x nominal diameter (e.g., 6" for 1.5" hose), ensuring installation in compact mechanical spaces.
Q: Does it require special tools for adjustment?
A: No, adjustments can be made with standard hex keys and wrenches, simplifying on-site modifications during system upgrades.
