DSP Fire Hose Coupling

In the fields of fire emergency rescue and industrial fluid transmission, couplings, as key components connecting hoses, pump sets and equipment, their performance directly determines the transmission efficiency and safety stability. As a typical representative of French locked couplings, DSP fire hose couplings have become the mainstream equipment in the fire protection systems of European countries such as France and Belgium, relying on their advantages of symmetrical design, quick locking and reliable sealing. At the same time, they are widely used in the global industrial fire protection field, serving as core connecting components that balance convenience and safety.

DSP fire hose coupling, full name Guillemin Symmetrical DSP Fire Hose Coupling, is essentially a French symmetrical quick-connect coupling. The "DSP" in its name originates from its symmetrical structure design and French standard system, while "Lock Ring" is its core feature, so it is often directly referred to as "French locked fire hose coupling" in the industry. It strictly complies with the European standard EN 14420-8 and relevant French standards such as NF E 29-572 and NF S 61-704, ensuring the versatility and standardization of the product, and adapting to the connection needs of various fire hoses and fire equipment.
