Brass hardlines have been used since the 80s.
But with better fittings, like compression, or banjo style. Push/pull fittings are not really sutable because the pressure rating is FAR too low, and tends to leak.
Plus rather pointless since the tubing is not flexible enough, you would need to remove the fitting just to remove the line. Thats why banjo, or compression fittings are much better.
