Essential details
Specification Number:Aluminum Storz Locking Reducer
Product Introduction
Definition
Aluminum Storz Locking Reducer is a double-ended Storz bayonet fitting designed for pipe diameter conversion. It connects two different caliber Storz couplings to realize seamless transition in fire pipelines and fluid systems. Compliance Standard: DIN 14301 / EN 14420-6. Made of high-strength lightweight aluminum alloy, with excellent pressure resistance and oxidation resistance. Fully interchangeable with all standard Storz fire fittings worldwide.
Key Features
✅ Premium Lightweight Aluminum Alloy
Integral die-cast forming with high mechanical toughness. Lighter than brass and steel fittings, easy to carry and install for fire rescue and industrial piping.
⚡ Dual Storz Bayonet Connection
Double-end symmetrical Storz lugs, tool-free push-and-twist locking, quick assembly and disassembly for emergency pipeline conversion.
💧 Zero Leakage Sealing Performance
Equipped with high-elastic rubber gaskets on both ends, maintaining tight sealing under rated pressure, no seepage during high-flow fluid transmission.
🌦️ Excellent Anti-Corrosion Treatment
Natural anodized surface treatment forms a dense protective layer, resisting rust, moisture and mild chemical corrosion for long-term outdoor usage.
🔁 Precision Reducing Transition
Smooth inner bore reducing design reduces fluid resistance, avoids flow turbulence, ensures stable water delivery performance.
💪High Pressure Resistance
Standard working pressure reaches 16 Bar, suitable for long-term pressurized water delivery in fire and industrial systems.
