Branch couplings, Storz couplings

Storz branch couplings and fittings are widely used in firefighting and industrial applications where fast, secure hose connections are essential. In this category you will find a broad selection of Storz couplings, branch couplings and related accessories designed to help you build safe, reliable hose systems.

Storz couplings use a symmetrical, quarter‑turn connection. This means there is no male or female side: both ends are identical, so hoses can be joined quickly and intuitively, even in low‑visibility or emergency conditions. The simple locking system reduces the time needed for setup and disassembly, which is especially important for firefighting teams and emergency services.

Branch couplings (also called stub or outlet couplings) are typically mounted on fixed pipework, hydrants, pumps, tanks or manifolds. They create a stable, sealed connection point where you can attach Storz hose couplings. Depending on the design, they may have threaded, flanged or weld‑on ends, allowing them to be integrated into a wide variety of systems. When choosing a product, pay attention to the nominal size, thread type and material to ensure full compatibility with your existing equipment.

Within this category you can usually find:

• Storz branch couplings with internal or external threads for connecting to pipes and valves
• Fixed Storz outlets for hydrants, pumps and distribution manifolds
• Transition pieces between different thread standards and Storz sizes
• Protective caps and covers that help keep connection points clean when not in use

The video above provides a clear visual overview of the most common Storz sizes and how to identify them. This can be especially useful if you are replacing older fittings or combining components from different systems. Matching the correct coupling size is essential to maintain leak‑tightness and safe operation under pressure.

When selecting a coupling, consider the following points:

• Size and standard – Check the nominal diameter and Storz size marking on your existing hoses or fittings.
• Connection type – Choose from threaded, flanged or weld‑on versions according to your installation.
• Material – Common options include aluminium alloys and brass, each suited to different environments and media.
• Application – Firefighting, irrigation, industrial water transfer and other uses may have different requirements.

All products in this category are designed for practical, everyday use and to integrate into typical hose and pipe systems. By combining the information from the video with the downloadable metric thread chart, you can quickly determine which branch coupling or Storz fitting is the right match for your setup.

Scroll through the product list to compare the available versions, then select the coupling that best fits your technical needs and installation conditions. Detailed product pages usually include dimensions, thread specifications and other key data to support your choice.
