Storz reducer couplings

A STORZ reducer coupling is a quick-connect adapter designed to connect hoses or pipes of different diameters within the STORZ coupling system. It enables seamless transitions between different sizes while maintaining a secure and leak-proof connection.

Key features

• Symmetrical (sexless) design – both ends are identical, allowing easy connection in any orientation
• Quick connection – requires only a quarter-turn to lock
• Threadless system – uses interlocking lugs instead of threads
• Leak-tight sealing – ensured by internal gasket
• High pressure resistance – suitable for demanding environments

Applications

• Connecting hoses of different diameters
• Adapting between STORZ sizes (e.g., 5" to 2.5")
• Commonly used in:
  • firefighting systems
  • water supply networks
  • industrial and agricultural operations

Construction and materials

• Typically made of:
  • forged aluminum
  • brass
  • stainless steel
• Equipped with locking lugs for quick engagement
• Includes sealing gasket for tight connection

Advantages

• Fast and easy operation in emergency situations
• High compatibility between different sizes
• Durable and corrosion-resistant
• Widely standardized and used across Europe
