This brass adapter cap in high-quality brass is the essential accessory to transform your 1000-litre rainwater collection tank (IBC / GRV) into a genuine watering station. Designed for direct installation on your tank valve, it ensures a robust and leak-proof transition between the tank-specific threading and standard garden accessories.
This fitting features a female S60x6 inlet, the most widespread standard on 1000-litre plastic tanks. It screws directly onto the outlet thread of your valve (external diameter of 60 mm, coarse threads). Its female 3/4'' (20x27 mm) outlet is ideally sized to accommodate a garden tap, a tap nozzle or any other quick-connect fitting, allowing you to draw stored water with ease.
Unlike plastic adapters that can weaken under the effect of UV rays or temperature variations, this solid brass model offers exceptional mechanical resistance. Weighing 120 g, it ensures precise threading and increased durability, even during intensive use throughout the summer season. It is the ideal investment to extend the life of your water recovery system and facilitate the maintenance of your vegetable garden or flower beds.
Assembly takes just a few seconds without any specific tools. For optimal sealing, we recommend checking that the gasket is present at the base of the S60x6 fitting and, if necessary, adding a few turns of PTFE tape to the thread of your tap when mounting it on the 3/4 inch outlet. This fitting simplifies gravity-fed watering or can serve as a base for connecting a surface pump to your water reserve.

Before ordering, make sure that your tank valve conforms to the S60x6 standard. This standard corresponds to a valve outlet with an external thread diameter of approximately 60 mm and a thread pitch (distance between threads) of 6 mm. If your valve has very fine threads (gas type), this adapter will not be compatible without an intermediate fitting.
