Gardena Hose Coupling 931-50 — 19mm to 13mm Hose Connector & Hose Joining Fitting
The Gardena Hose Coupling 931-50 is a versatile, click-fit hose joining fitting that handles two of the most common hose connection tasks in a single, compact component — securely joining two lengths of hose end-to-end, and bridging the transition between 19mm (3/4 inch) and 13mm (1/2 inch) hose diameters where a change in hose size is needed mid-run. Fully compatible with the entire Gardena system and built to the same UV-stabilised, weather-resistant standard as the rest of the Gardena range, this coupling installs without tools and delivers a secure, leak-free connection that holds reliably under mains water pressure.
What makes the Gardena 931-50 a genuinely useful fitting to have on hand in any outdoor water setup is its dual-purpose flexibility. As a straight coupler it joins two hoses of the same diameter cleanly and securely — extending a run, repairing a cut, or splitting a long hose into two shorter sections that store more easily. As a reducer coupling it bridges the 19mm-to-13mm diameter change that commonly occurs when connecting hoses of different generations, different brands, or different applications — eliminating the need for separate reducing adapters and keeping the Gardena system connection chain intact throughout. The Gardena click-fit mechanism means connection and disconnection takes one hand and one second — no threading, no tools, no leaking joints under pressure.
Built from the same durable, grey UV-stabilised plastic as the wider Gardena system range, the 931-50 is engineered for year-round outdoor use without the brittleness, cracking, or colour degradation that cheaper generic couplings develop after a season or two of outdoor exposure.
Gardena system compatible Connects two hoses securely end-to-end. Suitable for same-diameter joining and 19mm (3/4 inch) to 13mm (1/2 inch) diameter transition. Fully compatible with all original Gardena system parts.
