Another pipe question. Help please

[Oscarpop]

I need to tee off my raw water inlet for the water maker.

So 2 questions.

1 As it is going to be seawater, do I want a brass or nylon t joint?
Or should I source a stainless one.


2. I want to find a barbed t joint that is 26mm for the engine, and then a 13 mm tee for the water maker .

Can't find anything for love nor money in the UK

For water maker get water from forward, I mean from before the heads
Plastic or bronze/DZR, brass can corrode, sometimes in a year or two if unlucky...

T with reduction is possible, normal thing, but I also found it hard to shop in UK for some plumbing. You can put reduction farther on the way, for instance on the machine inlet.
