In emergency firefighting scenarios, every second counts, and equipment reliability can mean the difference between success and disaster. Our Swivel Elbow emerges as a game-changing solution designed to eliminate critical bottlenecks in fire hose connectivity. Crafted specifically for high-pressure water supply systems, this innovative fitting bridges fire trucks and hydrants with unprecedented flexibility, ensuring seamless water flow when it matters most.
Constructed from forged aluminum-magnesium alloy A6061—a material celebrated for its exceptional strength-to-weight ratio—the swivel elbow undergoes specialized gold anodizing for superior corrosion resistance, making it durable in harsh environmental conditions. What truly sets this product apart is its dual-axis rotation capability, engineered to solve the age-old challenge of rigid hose connections that limit vehicle positioning during emergencies. With industry-leading pressure ratings and precision engineering, it meets the rigorous demands of modern firefighting operations while adhering to NFPA standards for hydraulic fittings.
Alloy Composition: The elbow body utilizes forged A6061 aluminum alloy, renowned for its mechanical properties that include high tensile strength and excellent machinability. This material choice ensures the fitting remains lightweight for easy handling without compromising on durability.
Corrosion Protection: The gold anodizing treatment creates a protective oxide layer on the surface, significantly enhancing resistance to rust, chemicals, and weathering—critical for outdoor firefighting applications where equipment faces constant exposure to moisture and debris.
Heat Treatment: The elbow undergoes T6 quenching and tempering, a three-step process involving solution heat treatment, water quenching, and artificial aging. This procedure increases tensile strength by up to 57% compared to untreated aluminum, enhancing its anti-explosive and pressure-resistant capabilities.
Dual-Axis Rotation: Featuring a double 45° rotating joint design, the elbow achieves 360° rotation along the Z-axis and 90° rotation on the X-plane. This multi-directional movement eliminates hose kinks and allows fire trucks to connect to hydrants from virtually any angle.
Pressure Ratings: With a nominal pressure of 2.5MPa for regular operation and an impressive test pressure of 4.0MPa, the swivel elbow exceeds standard safety requirements, ensuring reliable performance under extreme hydraulic stress.
Versatile Compatibility: Designed to handle water and water-foam mixtures, it integrates seamlessly with existing firefighting systems, supporting both sprinkler and standpipe applications as specified in NFPA guidelines.
The swivel elbow is engineered to address the critical needs of fire departments during emergency responses:
Flexible Vehicle Positioning: By enabling 360° rotation, it allows fire trucks to park up to 100 feet from hydrants while maintaining optimal hose alignment—a distance compliant with safety standards for fire department connections (FDCs).
Rapid Deployment: Its lightweight design and tool-free installation reduce setup time, a crucial factor in emergencies where delayed water supply can escalate casualties and property damage.
Beyond firefighting, this versatile fitting serves sectors requiring high-pressure fluid transfer with rotational flexibility, including:
Municipal water supply maintenance
Industrial cleaning systems
Agricultural irrigation networks
A6061 aluminum alloy offers an unbeatable combination of strength, corrosion resistance, and workability. When forged and heat-treated to T6 temper, it achieves the mechanical properties necessary to withstand the high pressures and physical stresses of firefighting operations.
The 360° Z-axis and 90° X-plane rotation prevents hose twisting and kinking, which can cause pressure drops or bursts. This design minimizes strain on both equipment and operators, reducing accident risks during high-stress scenarios.
Yes, it is engineered to fit 4-inch Storz-type connections—the industry standard for new FDC installations—ensuring compatibility with most North American fire hydrants and hose systems.
The gold anodizing layer provides passive corrosion protection, requiring minimal upkeep. Regular inspections for debris in the rotation joints and ensuring proper pressure ratings are observed will maintain optimal performance.
