I actually got the correct Red-Dot hoses for mine but that also required that I change to a different dryer and also to a different trinary switch and had to track down an obscure adapter to get that all to work together because the Red Dot dryer has different ports and the stock Red Dot / military wiring does not use a trinary switch but instead uses separate high pressure and fan switches that don't match the trinary switch I wanted to use.....
I did crimp my own hoses for my 24v mini-split system in my habitat though - this crimper works great:
My plan for hose was to just take the fittings to a local place that does a lot of AC work and have them match up hose for the fittings. From what I have seen the hose is labeled with both metric and standard sizes - apparently it's close enough. All the AC fittings are SAE I believe so the fittings are likely for SAE hoses but like I said the hose seems to be both SAE and metric since the dimensions are so close - 8mm or 5/16, 13mm or 1/2, etc.
