Hi all,
I am in the process of installing a 2.5kw split system to my old caravan, and being concerned about vibration and copper pipe thought id see what was available on the Australian market re flexible lines. A quick search brought up 'Spartaflex' but sadly there is an issue with operation re heat mode with a spilt system. Trawling the web a bit more brought up several products from Europe and the U.K. such as 'Armacell Flexifast' and 'Parker K-link' and others, but not readly available in OZ......after some more web trawling I located a Parker 'Parflex' refigerant hose
'510a' with a max pressure of 2500-3000 psi depending on the size.
http://www.hoseandfittingsetc.com/product/hose/510a-hose/
The i.d. of the hoses to match the i.d. of the copper line is not exactly the same-
510a-3 is at 5mm is pretty close to the i.d. of 1/4" copper line but the i.d. of 3/8" copper line at approx 8mm does not quite match 510a-5 at 10mm i.d.....would this difference in size over a pipe run of 1.8 metres be an issue?
Providing my local hose doctor (Enzed) can source suitable flare fittings to suit the two hose sizes and crimp them on....would this work in theory?
Any thoughts or suggestions would be most appreciated.
