What type of hose coupling lacks male or female ends?

The Storz coupling is designed without distinct male or female ends; instead, it features a uniform design that allows for quick connection and disconnection. This coupling uses a unique interlocking system where two Storz couplings can be connected by aligning and twisting them together, which creates a secure seal.

This design is advantageous in firefighting scenarios, as it allows for rapid hose connections under pressure, which can be critical during emergencies when time is of the essence. The absence of gendered ends means that any Storz coupling can be connected to another with ease, eliminating the complications that can arise from trying to match male and female threads that are characteristic of threaded couplings or other types of hose connections.

In contrast, garden hose couplings typically have distinct male and female threads, and threaded couplings are characterized by their specific male or female ends that fit together through screwing action. Camlock couplings, while also facilitating quick connections, still possess male and female components to facilitate their locking mechanism.
