Pipe Coupling Question
Hey guys,
I'm trying to think of a way to couple two pieces of metal pipe. The problem is one of the pipes doesn't have a threaded end.. just smooth metal. The other pipe is threaded though, so that's an easy one.
I've used a compression coupler before (where it basically uses the force of the tightened nut to tighten a flanged piece of metal against the bare metal), but for some reason this just makes me nervous since it's for an airtight application (air conditioning).
Can anyone think of a better or more reassuring way that doesn't require a flange making kit or something similar?

It's pretty much just a custom AC setup. It's using an older AC compressor where the single metal bracket that bolts to the compressor has the high and low pressure lines coming out of it. Those two metal lines then have the rubber lines that run to the dryer and whatnot. It's where the steel compressor bracket meets the rubber lines that I'm working on.
I know I can simply clamp the rubber hose on, but I don't want to do that. The end of the lines already have a screw connector. It's the compressor bracket that has two steel pipes with no threading that I'm working on. They were cut because the original wasn't a screw-on. It had a proprietary clamp, and was then cut because it wasn't long enough for my setup.
Sorry that it sounds kind of complicated.. that's why I left it simple in the first place, but the mundane details can end up meaning a lot.
I'll probably end up going with the compression fitting afterall.

Re: Pipe Coupling Question (Tourney3p0)
without seeing it its hard to tell but if you are going to push a hose over the end of a metal tube it probably will not seal unless it has barbs. maybe you can find some one to make up a new hose set for you or get your local welding shop to weld it together.
