Can the SEP-4 combination dirt,mag,air seperator be used on a radiant system without oxygen barrier tubing? Is the inside of the SEP-4 bare steel? Most of my system has oxygen barrier tubing, but the basement slab was installed about 10 years ago with non-oxygen barrier tubing. It has never been hooked up until now. The house is forced-air heating, but soon will be radiant.
