Hose clips around the connection point are highly recommended — they guarantee a watertight seal and prevent any moisture escaping during the flood and drain cycle.

You'll need 2 washers and 1 nut per fitting to complete the connection to your pots. Buy these separately if you don't already have them — they're cheap and essential for a proper seal.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe size:\u003c\/strong\u003e 25mm internal diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Double-barbed push-fit connectors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection method:\u003c\/strong\u003e Barbs grip flexi-pipe; screw thread for pot insertion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Durable plastic with barbed grip design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure rating:\u003c\/strong\u003e Higher pressure tolerance than generic fittings due to barbed construction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with:\u003c\/strong\u003e IWS Pro systems, IWS Standard systems, 25mm IWS flexi-pipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired accessories:\u003c\/strong\u003e 2 × 25mm washers and 1 × 25mm nut per fitting (sold separately); hose clips recommended for installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIWS system owners expanding their setup with additional modules\u003c\/li\u003e\n\u003cli\u003eGrowers replacing worn, damaged, or lost fittings mid-cycle\u003c\/li\u003e\n\u003cli\u003eAnyone building a custom IWS layout tailored to their growing space\u003c\/li\u003e\n\u003cli\u003eExperienced flood and drain growers who trust IWS reliability and want genuine parts\u003c\/li\u003e\n\u003cli\u003eGrowers scaling from small to medium setups without changing the core system architecture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eIf you've got an IWS system running, these fittings are exactly what you need — genuine components that fit properly, seal tight, and don't cause headaches.
