"sucker" flexible ducting source?

Try an air conditioning suppliers, or a ducting manufacturer. If you were in New Zealand, I could score you some... One brand is "haflex". What about looking for undustrial hose suppliers in the yellow pages? Geoff

thermoplastic,

Might try a good electrical supply house for flexible metal conduit-probably $$$$$$$$$$$ though

If you are looking for SS ducting - get ye to the local wood stove store. When the earthquake of '89 shook the bay area - many houses with fire places went to 'inserts' and a SS duct. The duct saves many thousands of USD replacing a shattered but still standing strong. All inserts use it.

Mart> Grant, I don't know if this is the same stuff, but the place I've found

Looks like my isp is still dragging in headers - some days late. It just bought out another and merged both groups into yet another domain site. Such is life.

Wood stoves inserts - aka - wood stove store - maybe they have a short section left over from a job.

Forgot all about those-good idea! Liners are also used when venting a higher efficiency furnace in a masonry chimney...
