Which hose coupling style has the same design on both ends of the hose?

The Storz-type coupling is distinguished by its unique design that features a symmetrical connection on both ends of the hose. This characteristic allows for a quick, easy, and secure coupling without the need to align threads, which can sometimes be a time-consuming process in emergencies. The design typically uses a two or four lugs that can be easily rotated and locked into place by simply pushing two hoses together, making it highly efficient for rapid deployment in firefighting scenarios.

The versatility and speed of connection provided by Storz couplings make them particularly valuable in situations where time is critical. This coupling style is commonly used in municipal fire services, especially for larger hoses in high-volume water delivery systems.
