Water Maker Scaling up with generic of the shelf parts.

I am in the final stages of getting a watermaker implemented. I am looking for a supplier of the teflon cored/stainless/silicone high pressure hose. Can't find anyone locally. Any suggestions?

I had my HP hose made by a a company that does digger pipes , the fittings are SS , 800 psi is nothing when it comes to the pressure these machine need remember to only sea water that's passing through these hoses

We brought it in Malta , it's where we was at the time ,
To be honest I could say if they where teflon or not , Wired R2 hydraulic hose it's what used on HP machiney as in jcb digger , cranes , HP water pipes , they rated for water .
I don't think they need to be any thing special, as I said it's sea water that goes through them only once out the vessels on the product side you want to think about using good quality water pipe , the brine water side you can use any pipe , I just used reinforced plastic pipe .
You can make RO water makers as simply or as complicated as you want , I seen one that does everything for you as well as starting up at a set time .

When I was building my watermaker i was told to spec the HP hose at 2000-3000 psi. System will never see more than 1000psi but it provides a factor of safety and robustness. The hose doesnt cost a lot more for higher pressure. I just had a new s/s braided 1/4 inch hose 2ft long made up in Panama For £44 complete with swivel fittings for 1/4NPT threads.
