Buying Storz System Couplings and Hoses — Guide & Tips
In the category Storz System Couplings and Hoses you will find 97 items for the secure connection of hoses in irrigation, construction, agriculture, and firefighting. The Storz system features standardized couplings that can be connected without tools in seconds. The compatibility of the sizes – from the small D-coupling to the large A-coupling – is crucial for choosing the right product.
When buying, pay attention to standardized designations such as DIN 75-B or DIN 52-C, which define the diameter and pressure rating. For the hobby gardener, a C-coupling with a diameter of 50 mm is often sufficient, while in professional use or at the fire department, larger B or A couplings are used. The material quality of the couplings – whether aluminum, brass, or plastic – affects durability and weight. For continuous outdoor use, corrosion-resistant versions are recommended.
The appropriate Hoses complete the system: Pressure hoses with Storz couplings are suitable for transporting water under pressure, while suction hoses are designed for drawing water from open waters or cisterns. Pay attention to the correct combination of coupling and hose diameter to avoid pressure loss. For permanent installation in the garden or on the construction site, investing in high-quality couplings with sealing rings that enable drip-free operation is worthwhile.

Industrial hose 15m, C52 pressure hose
A ready-assembled pressure hose with Storz couplings on both ends. Suitable for continuous use on construction sites and in agriculture.
To the productThese three product types cover the most common areas of use: The D-coupling is suitable for fine connection to household water connections, the C-coupling is the all-rounder for medium flow rates, and the finished pressure hose with C52 couplings offers a ready-to-use solution for work in the field or on the construction site. When selecting, you should consider the required diameter and pressure resistance of your existing system. For connecting different coupling sizes, there are special reducers available separately.
Frequently Asked Questions
Which Storz size do I need for my garden hose?
For a typical garden hose with a diameter of 1/2 inch or 3/4 inch, Storz size D or C is usually used. The D coupling (approx. 25 mm) fits thinner hoses and water taps, while the C coupling (50 mm) is designed for thicker pressure hoses and higher flow rates. Measure the outer diameter of your hose or check the existing fitting to choose the correct size. If in doubt, the C coupling is the safer choice for most garden watering tasks.
Can I combine Storz couplings with other systems?
Storz couplings are standardized and compatible with each other – a D coupling fits any other D coupling. For connection to threaded fittings (e.g., a faucet with 3/4 inch external thread), you need adapters with internal thread, such as the Storz D coupling with 3/4" internal thread. For transitioning between different Storz sizes (e.g., from C to D), reducing pieces are available. Ensure that the sealing rings are intact to prevent leaks.
Which material is best for Storz couplings?
Aluminum is the most common material for Storz couplings, as it is lightweight and corrosion-resistant. Brass offers higher strength and is suitable for extreme pressure loads, but is heavier. Plastic couplings are cheaper and rust-free, but less robust under mechanical stress. For private garden use, aluminum or plastic couplings are perfectly sufficient. In professional use or for fire departments, aluminum or brass couplings are the better choice.
How do I properly care for my Storz couplings?
After use, rinse the couplings with clear water to remove dirt and residues. Check the sealing rings for cracks or deformation and replace them if necessary. Store the couplings dry and protected from direct sunlight to preserve the material. For aluminum couplings, a thin film of silicone grease can maintain the locking mechanism's mobility and prevent corrosion. Avoid contact with aggressive chemicals.
More categories
If you are looking for specific hose types or connection elements, you will find them in the hoses the matching overview. For flexible wastewater pipes, we recommend the drain hoses that are used in washing machines or sinks. If you need hoses for the vacuum range, the suction and pressure hoses are the right choice – they are reinforced and optimized for pump connections.
For fastening and sealing your hose connections, the clamps provide a reliable solution for fixing hoses to fittings. If you are working with plastic pipes, the Hose connectors made of POM plastic, a lightweight and corrosion-free alternative to metal connectors. These categories complement the Storz system and help you complete your entire irrigation or hose installation.
In a nutshell
In this category with 97 items, you will find Storz couplings and hoses for irrigation, construction, and firefighting. Choosing the right size (D, C, B, A) and material (aluminum, brass, plastic) determines the possible applications. For the garden, the C coupling is usually sufficient; for professional use, larger sizes and pressure ratings are required. Pay attention to compatibility with your existing connections and use adapters for transitioning to threaded connections. The combination with suitable hoses and clamps completes your system.
