Storz self-locking fire hose coupling in aluminium

Hose Coupling

Storz Self-loking Coupling

The Storz self-locking coupling is a fire hose connection with a built-in locking mechanism, so no separate locking device or tool is needed to make a secure joint.

Product Overview

What This Hose Is Built To Do

The Storz self-locking coupling is a fire hose connection with a built-in locking mechanism, so no separate locking device or tool is needed to make a secure joint. It is made to DIN14301 and DIN14303 in aluminium, cast or forged and anodised, from 4 to 14 inch (DN100 to DN350). For large diameter fire and industrial lines, the self-locking action is a safety feature as much as a convenience.

Key Benefits

  • Self-locking mechanism removes the need for a separate locking device or tool
  • Made to DIN14301 and DIN14303, so it interoperates with standard Storz equipment
  • 4 to 14 inch range covers large diameter supply lines other Storz ranges do not reach
  • Anodised aluminium for corrosion resistance in outdoor service
