This drum tap in cap fits our 20L Reservoir Cubes for Nutrient Storage (KB32497) . They all have a opening diameter of 58mm. These are a fantastic solution for leak free storage and easy dispensing of hydroponic nutrient or chemicals.

All you need to do is unscrew the lid and screw one of these on. Then tip the drum on its side and turn the tap to dispense. This tap has an inbuilt breather so it lets the air back into the drum as the liquid drains out. It saves you having to open the bung at the bottom. Once you are finished dispensing, turn the tap off and it will never leak.
