Looking for a fitting, does it even exist?

[ABCwarrior]

Hi folks,

After trying everything possible to remove water hammer from the HW supply (through a thermal store, mains pressure, set to 3.5 bar static, CW supply no issues, not the washing machine!) which I realise isn't helped by lever taps the missus slams shut, I want to fit some water hammer arrestors of the 1/2" BSP type. I'm really struggling, considering how common this is, to find a Tee connector that I could just attach to the tap connections that would have the branch off to add the arrestor of my choice, everything seems to be 15mm+15mm with the 1/2" BSP off of it, or it's ALL 3/4" BSP as it assumes only washing machines are the problem. Seems a fairly simple idea, you get water hammer, you undo the tail and put this in place and screw it together without having to cut into pipework? Does this exist? Gone round in circles trying to find what should be such a simple solution!!!! (so, female 1/2" BSP through to male 1/2" BSP with a female 1/2" BSP Tee'd off in the middle at 90 degrees)
TIA

No Elsa, thanks for replying though, In the first link imagine if the 2x 15mm ends were replaced by a male and a female 1/2" BSP. Then I could just undo the tap tail nut and insert this between the fixed pipe and the flexi tail. Then add the arrestor into the vacant female branch coming off the middle- like a Sioux Chief AA (and if that fails try another brand). Both the things you linked to involve cutting into pipework which to my brain seems totally unnecessary and something I'm wanting to leave to a last resort.
Sioux chief make this "slot in" unit for washing machines and only in 3/4"- NOT 1/2" which if they did would surely would be perfect for taps!!

Maybe the 3/4" Sioux thing with some reducers at either end would work...more connections, more leaks lol....

I don't think I'm understanding

Pardon our interruption...

Only issue is that the male end is solid, not a nut, so it’s pot luck whether it points in a convenient direction for the arrester when you screw it up. Is that what you were expecting?

Still think I'm not understanding this correctly.

But what you use this tee

Then wind a male copper to iron in the bottom.

Yes, pretty much it but hoped the female end nut was independent of the body so, as you say, it could be positioned in a direction to suit and not end up facing into the wall or something. This seems to be the case with the out of the box washing machine ones. Yet no options in 1/2". Bizarre. Oh well, pipe slice it is, decided on a 0.16L chamber now as these Sioux Chiefs get pretty poor reviews and the others can be "tuned" with countering air pressure from a pump(Rock Shox fork pump will be ideal!). Just make it as accessible as possible in case they have short working lives and need switched out....
