Qruck’s Storz X NH/NST adapters is a specialized fitting used to connect a Storz coupling to an NH (National Hose) / NST (National Standard Thread) coupling. The adapter typically features a Storz female or male connector on one end and a female NH/NST swivel thread on the other. It enables interoperability between fire hoses, hydrants, or appliances from different regional standards without leakage or thread damage.

And both our Rigid Male Adapter and Swivel Female Adapter own more advantages as follows.
Enables cross-system compatibility - Allows firefighting equipment from European/industrial systems (Storz) to work seamlessly with North American systems (NH/NST).
Quick and reliable connection - Storz side requires only a quarter-turn to lock, reducing connection time compared to threaded NH/NST couplings.
Eliminates thread galling and cross-threading - The Storz genderless design avoids thread damage common with repeated NH/NST connections.
Secure and leak-proof seal - Storz uses a gasket seal independent of threads; combined with NH/NST's own gasket, the adapter provides double sealing reliability.
One-person operation - Storz coupling does not require precise alignment or high torque, making it easier to connect in low-visibility or high-stress environments.
Durable and corrosion-resistant - Typically made of hard-anodized aluminum or stainless steel for long service life in harsh conditions.
Both NST, NPSH straight thread and NPT Tapered Thread are available to our production. NPSH and NPT have the same number of teeth and outer diameter, but the threads are straight. The female head of NPSH can be screwed onto the male head of NPT as a temporary connection, but the reverse (NPSH male head connected to NPT female head) is not possible, and it does not guarantee the sealing effect In addition, due to the completely different geometric shapes and sealing principles, mixing NST with NPT can lead to serious leakage, and even damage to threads or connection failure.
