Can metal (stainless steel, copper, etc.) tubes be connected to SMC’s One-touch fittings?

KQ, KQB, and KQG series One-touch fittings and KF series insert fittings are not compatible with metal tubes. The SMC fittings that are compatible with metal tubes are the H/DL/L/LL series self-align fittings, though they are only compatible with soft copper tubes. The H/DL/L/LL series catalog can be found here.
