That tap thread is a fair bit smaller than the 3/4" washer fitting since you can push it on like that!
Maybe the tap is 5/8" BSP, in which case a 5/8" female to 3/4" male adapter would do it, such as:

5/8" x 3/4" x 1/2" Adaptor for Outside Tap / Bib Tap Garden Hose Pipe Connector | eBay

<p>Both ends have a male 3/4 inch BSP outer thread. One end has a 1/2 inch BSP female inner thread, the other a (rare) 5/8 inch BSP female inner thread, sometimes found on old bib taps.</p> <p>Use this brass adaptor fitting to allow connection of modern 3/4 inch Hozelock / Gardena type garden...

You would need ptfe tape with the above if it doesn't have a rubber washer to seal to the mouth of the tap.

Or maybe the tap is some wierd metric thread🤪

I would show that video to your local (Portugal?) plumbers merchant.

@Basher: According to the page Understanding Pipe Threads - https://www.thehosemaster.co.uk/bsp-pipe-threads a 5/8" should have a diameter between 22.911 mm and 20.589 mm, but as you can see in the attached photo, it's more on the 24 mm park 😕 It seems to be something else

@WC1: Yeah, I'm in Portugal. I've already visited the plumbing section of a big home improvement retail store (Leroy Merlin) but the staff there didn't have any clue regarding this problem 🙁

It looks like M24 is around as a plumbing thread somewhere in the world.
(Just as an example - wrong fitting!) Amazon productBut concerned the pitch on your tap is not as fine.

Do you have, or could borrow, vernier callipers to measure the tap thread and its pitch accurately?

I'm thinking it still might be 5/8" BSP, despite the apparent measurement?

Imo . Never ask for advice at a big box store. Ask local independent plumbing merchant.

So went to very old-school plumbing store, but they also couldn't explain the tiny difference, so I ended up replacing the tap with a standard 3/4" and it's solved. I also don't have vernier callipers 😕
Anyway, thanks Basher and WC1!

Think that tap looks like it’s for an outside hose pipe are those fittings slightly different
