These are 3/4" BSP Tank Adapters with an in-line Ball Valve and barbed hose tails at the other end.
They can be used with any tank or drum to provide a connection for various sizes of hose pipe.
Please note that the hose tail measurements refer to the INTERNAL Diameter of the hose pipe and the EXTERNAL Diameter of the hose tail.
They are available in 4 sizes (select from the drop down box above):
- 6 mm Hose Tail
- 10 mm Hose Tail
- 13 mm (1/2") Hose Tail
- 20 mm (3/4") Hose Tail
Firstly, you will need to drill a hole (25 / 27 mm diameter) where you want to locate the item.
Important.....You must be able to get your hand into the tank or drum somewhere close to enable tightening of the back nut. You will also need to make sure that the area where the hole is being drilled is reasonably flat.
You will not get a good watertight seal on a heavily curved surface (a slight contour will be OK).
Once you have drilled the hole, remove the back nut and rubber sealing washer from the adapter and push the threaded section through the hole.
Then push the rubber sealing washer back over the threaded section and finish by screwing home the back nut as tight as you can by hand. Do not overtighten.
