Can I uses a steel hose splicer in an automotive air conditioner system?

I have a '99 Chevy Astro Van AWD /w rear A/C. The low pressure line (hose) returning from from the evaporator in the back has a cut in it. Replacing the whole thing is insanely expensive and probably involves pulling the engine! Anyhow I am going to try to splice the line. Can I use a steel hose splicer, or is there a problem with using steel parts, will it corrode or something?
