Yeah, the only thing I'm thinking is that lowe's won't have an adapter from the 1/2npt to rubber soft line like I'm looking for, I'm thinking I'm going to have to go to a more automotive type place.
if you arent looking for the barb on the other end, then youll prob needa try somewhere that makes hydraulic lines.... some NAPAs do it, or try a place that specializes in tractors and equipment
they might not be exactly like that, they may have the multiple barb style (if that makes sense, i don't know the technical name) on the hose end but they should have them none the less.
they should be in the plumbing section like i said, or you may also find something where the air compressors/air tools/air accessories are.
