Those are just common brass nipples, connectors, adapters. You put them together in various configurations to get the connections you need.

Instead of using brass fittings to help make your connections, it would be better to buy new shut-off valves and hoses that meet your needs better. Instead of trying to reuse old ones.

Thanks for the reply! Replacing entire valve is a great idea, but I never attempted to replace one and at the same time I'm not affraid to give it try :)

Is it safe to assume that inlet is 1/2 FIP?
Something like this should work

House was build in 2006 so I don't think its soldered.

The fitting you showed is a screw on fitting requiring a 1/2" Male IP on the copper pipe coming out of the wall.

The existing shut-off valve may be a screw on fitting, you will need to shut-off the water supply and then try removing the valve. It is probably a compression fitting. Which is a brass or copper ferrule that has been compressed onto the copper pipe by by tightening the nut and the valve.

You may be able to reuse the nut and ferrule and put on a new valve. And tighten it enough so it won't leak.

If there is enough pipe left, you can cut it off and put on a new compression fitting, or, a push to connect fitting like a shark bite.

And, I would suggest getting a 1/4 turn instead of a multi-turn. Much quicker to shut off the water in case of leaks.

Here is a compression fitting in the quarter-turn variety:


And here is a PTC valve in a 1/4 turn with a supply hose attached:
