Flexible hose in Air con piping

[Hossein]

Dear all

is it possible to use flexible high pressure hose (like hydraulic hose) to connect air con split system instead of using copper pipe?
I have got problems piping copper tube through the wall and ceiling and connecting to outdoor system.

Short answer - no.

Long answer. Get a fridgy to have a look at it. It is very surprising where a fridgy is able to put pipework. There are various tricks of the trade!

I'll disagree with Tas_Dean on "technicalities"... but for all intents and purposes he's right.

Braided a/c line is available (look at any auto a/c) at suitable specs for domestic a/c, however the price is astronomical compared to solid line, as are the fittings, and it is nowhere near as durable in the long term. AND you'd still need a licensed a/c installer to fit it...
