Capping washing machine hot water intake

[New2DIY123]

I have a new washing machine which doesn't need the hot water any more. I bought the blanking and tighten it. But if you turn the little tap it still leaks.
Anything I am missing?

Thanks

Did you fit a rubber washer under the brass blanking nut?

Yes

It's not leaking from the tap gland itself, by any chance rather than through the cap nut threads? Not unknown!

I have lined it in blue. You can see the water still comes out. Right now the tap is off, I am just worried I accidentally turn it on by hitting it etc.

Get ones of these plastic ones -

good and hand tight should do it.

The brass ones really needs a pair of grips/adjustables just to nip it up enough.

I bought the tools to grip and tighten it already and I am afraid to do any more in case I break or bend the pipe.
Can you tell me exactly what the plastic one is called?

Never mind I found it on eBay. I will buy that and try it as well.
Thank you.

It is possible to overtighten, which will damage the washer so that it never seals.
Hand tight and then 1/4 turn with a tool should be adequate.

Thank you all.
