Pex size for 22mm

I know 15mm and 1/2 fittings are pretty much interchangeable.
I have a set of bath taps that take a 22mm.

What about 22mm & 3/4 compression fittings?

Thanks

Did you buy the bath tap in Ireland or was it imported?

That should still be a 3/4" tail. Go into your local plumbing supplier with the tap and ask to see if a 3/4" -312 connection screws onto it, it should.
Probably better and easier for you if you buy two 3/4" flexible hoses as the 312 connections need flax or a lot of tape to ensure a good water tight connection.

Thanks K flyer.
I'll double check the tails this evening.
The bath is a free standing one with standpipes going to a concrete floor so its a bit tricky and needs to be right first time.

I was doing a test fit yesterday and I had it in my head that the taps would be 1/2" with a 1/2" supply.
I'll have to open up my floor chase a bit to get the 3/4" pipe in but rather now than when its finished

If 1/2" is coming out of the floor you could get away with it, but filling the bath may take a little bit longer.
Ask in the supplier for a 3/4" to 1/2" 312 which will allow 1/2" pipe or flexible hoses to connect to the tap.
Or use 3/4" flexible hoses which will screw straight onto the tap and use a 3/4 to 1/2" reducer to connect to the 1/2" pipework.
