Hokare Storz Coupling
Storz couplings are frequently used as fire hose couplings or fittings. Made according to German standards (DIN143). It is typically made of brass, stainless steel, and aluminum alloy. Storz couplings are symmetrical non-shut-off couplings. These couplings are ideal for working with water, acids, and other fluids. It can be applied as connecting couplings for connecting different hose types.
Hokare has specialized in Storz coupling manufacturing for many years. We have a massive stock of Storz coupling in standard sizes and specifications, also available in full customization. Buy with confidence here at Hokare.

Storz Coupling High-Quality Material and Advanced Process
Storz couplings are made from common materials such as:
- Stainless Steel – excellent corrosion resistance, temperature resistant, very durable material
- Brass – low-friction, high-strength, malleable, and easily machined metal for Storz coupling production.
- Aluminium – rust-resistance, machined and molded quickly to form Storz coupling. Solid and durable, withstand acids, water, etc.
For firefighting applications, Storz couplings can be manufactured by forging to ensure the coupling’s safety and durability. We also use the casting method for general hose connection and low-pressure applications.

Storz Coupling Lug Distance
The lug distance makes Storz couplings simple to recognize. Using a pair of calipers, measure the interior space between the lugs of a coupling to determine its lug distance. The most popular Storz couplings and their lug distances are listed below. Frequently referred to with a letter classification.
Lug distance 89 mm | B-couplings |
Lug distance 133 mm | A-couplings |
Lug distance 66 mm | C-couplings |
Lug distance 31 mm | D-couplings |
