male/female/female 15mm tee

I can't seem to find such tee being sold in the UK. In the US they have something like this:

You could make one up from a femail tee and a straight nipple. but really have to ask, why?

I was hoping to avoid multiple connections, but if that is the only way...

I need to connect a 15mm water hammer arrester to sink tap supply which already have isolation valve installed (male end, hence needs for 2 females on the tee, one for arrester, one for isolation valve)

Are they suitable for Uk potable water supply ?

Plenty of approved water fittings on the uk market,have in the past used mini expansion vessels to reduce water hammer but any arrester will not cure poorly installed plumbing,water taps that slam shut & so on .

Plumbing is indeed poor. When we moved into the house a few years ago I didn't really have experience with these things, so when full cosmetic redecoration was going on, the plumbing and heating was not touched. Now that I have done and read about fair bit of dyi I'm starting to rectify things myself.

Water hammer issue - I tried fitting a water arrester yesterday to a washing machine, and at least in my situation it worked beautifully (that arrester came with 3/4 fittings out of the box, so I didn't have to worry about adapters). So now i will be trying the same for taps/toilets.

I've read that effectiveness of them is quite local, I.e they have to be within a couple of meters of the closure point. How effective are those expansion vessels (which I considered as well, but discarded for the above reason)?

O ye, of little faith?

End result (one if them). Of course I did use washers and tape, but all good in the end. The biggest challenge was to rotate it in the right position. I wish they did such tees with a nut, so that it could be turned without moving the tee...
