Male Water Butt Tank Connectors with Washer

These adapters come with a 1/2", 3/4" or 1" BSP male thread and can be inserted into an existing water tank thread with a BSP Female thread. If your tank is not compatible or has no outlet, these adapters come with a nut and two washers which can be used to seal a drilled hole.

BSP (British Standard Pipe) is a standard pipe thread size used in the UK. The size of a BSP pipe is specified by its nominal diameter, which is measured in inches. However, BSP sizes are different from the actual physical diameter of the thread.
