These are 3/4" BSP Tank Adapters with an in-line Ball Valve and BSP male or female thread at the other end.
They can be used with any tank or drum to provide a connection for various fittings.
They are available in 4 types (select from the drop down box above):
- 1/2" BSP Male Thread
- 3/4" BSP Male Thread
- 1/2" BSP Female Thread
- 3/4" BSP Female Thread
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.
