Material for hydraulic hard lines, Copper-Nickel or only steel?

[Egon]

Compression fittings for a 2100 PSI system? I was having a hard time convincing myself to use them on the tank return line, which I have have to resort to.

I tried removing the JIC male adapter threaded into the tank return on the hydrostatic, to figure out a replacement, so I could insert a T in that space, but managed about three turns before it got very hard to turn. Discretion VS VS Valor convinced me to thread it back in and go a different route. Guessing it is one of those tapered pipe threads and is well and truly distorted.

proper rated compression fittings. There are different types but you will not find them at the local hardware. A proper fittings shop can help.

Joea99, if you were closer I could bend and flare steel lines while you wait, I have .250” to 1.500”.
Some types of stainless tubing doesn’t like to bend or flare, you would need to specify annealed tubing.

Thanks for the offer and tip. It is close to a 4 hour drive, one way. For future reference, do you replicate and ship as well?

I'm assuming he used that as a general term, and what he really means is "swagelock" style fittings, they are made for high pressure use.
