This IBC coupling is used to join the IBC gate valve to other metric fittings. It can also be used to join IBC's together.
The female to female coupling has a 50mm BSP thread on one side, and a coarse 2" thread on the other.
The coarse thread suits many IBC outlets, and the 50mm BSP thread can be joined to a reducing nipple (for example a 2 inch to 1 inch), and a nut & tail fitting (1 inch to 1/2 inch barb), to connect to your garden hose.
IBC tank's (integrated bulk carrier's) are used a cost effective method to collect rainwater and greywater for the garden.
