Pressure reducer/regulator for plastic water line?

Good evening,

Wondering if i could get a little guidance, I have a 3/8 plastic line running from a softener to a coffee machine (because laziness), however the line pressure seems to be maybe 2.5 bar. The manufacturer state the max line pressure is 2 bar (29 PSI). for the life of me i cant find a device to let me lower the pressure in the line which will connect to the 3/8 plastic line. im happy to throw on some adaptors, but it doesnt seem very easy to get a 3/6 push fit to 15mm thread adaptor.

could someone point me in the right direction?

Cheers
 
Manufacturers generally have parts available that can suit the pipe they supply.
There should be plenty of suppliers that will have something suitable to connect to the 3/8 plastic line, without any adapters needed
 
To lower the pressure in your 3/8" line, try using a small inline pressure regulator that fits 3/8" push-fit connections. If you can’t find one, use a regular pressure reducer with adapters to connect it to your line. Another option is a pressure regulator with compression fittings, adding adapters to fit it onto the 3/8" line. A plumbing supplier might help you find the right parts if needed.
