Those bauer couplings are very lossy, but it depends on flows and pressures.. may not be an issue for youLots of tubes! Was only £22 for 2 bundles of 5x ~4" 6m long and 1 lot of 5x ~6" 3m long. Hopefully once I get them straightened and checked I might be able to use them for a turgo turbine micro hydro setup penstock but if not not a massive loss cost wise.
