I have a Torbeck inlet valve for a new toilet I intend to fit today. Problem is, its a bottom inlet valve and the brass thread that goes through the cistern has no internal shoulder to push up a pipe and screw on in fact the hole is very small. There is an additional threaded nut on the outside, but no instructions or apprant way for connecting the copper (or plastic) incoming mains to this see pic

bought this fitting, which fits, but presumably I use PTFE tape on the 2 touching brass threads and make sure the rubber washer sits inside?

this right?/wrong? can anyone help me find a way to connect the pipework to this please? thanks

The message from "Vass" contains these words:

The rubber will bear directly on the nose of the inner thread, so there's no need to seal between the two brass threads.

I'd say the adapter on the left is designed to mate and seal with the larger threaded piece on the right, it may incidentally seal the smaller pipe too but that's not guaranteed, seal the threads too.

Personally, I'd not use the brass adaptor or the push fit fixing. I'd use a

1/2" tap connector (usually right angle "serviceman", with built in isolation valve), which is what toilet fill valves invariably require.

Personally, I'd use a chrome compression type to connect to chrome pipe into the wall. I'd only switch to plastic when it wasn't in view.

you must use push fit:

doesn't have a valve built in, but is white, so would look better than a grey system on modern sanitaryware.
