Kair 125mm x 3m PVC Flexible Ducting Hose

Genial para alargar más el tubo de mi aire acondicionado portatil de 127mm de diametro.

I used it to extend my portable AC. It fits well and works fine.

This did the job for a while, and is exactly as shown. But after about a year the wires have started to tear through the plastic. Because the plastic is so thin, it isn't very efficient for anything heat related.

Revived my portable AC machine in this hot weather, good length, pleased with delivery and purpose.

Bought to replace the old vent hose from my AC unit that died last year, and was the right size at a reasonable price. Actually, no idea what this sort of thing should cost, but know there were some expensive options last time I looked. Made out of spiral wire with flexible PVC hose, so very 'malleable'. Only issue I had was due to this flex, as it no longer locked tight into the screw-threads on my AC unit (old hose was rigid plastic stuff that 'snapped' into shape) - but easily fixed with some duct-tape. #edit "Be careful" My AC unit came with a plastic hose that was maybe 5ft in length - and I was very happy about how I could move the unit further from the window, once I'd attached this longer hose. Then when it got hot, I thought my AC had broken. The compressor was making an awful noise, and nothing was getting cooled. The problem was the length of this hose (not the hose's fault) as it was way longer than what my AC had come with. Long hose, reduced the air my AC could push over the hot radiator, so it didn't condense properly, so pump was trying to push liquid and gas and really wasn't happy. Hose length you got with your AC has probably been worked as as maximum efficient length. I've just cut this hose down to 5ft, and my AC is now working perfectly. i.e. this is a great replacement for whatever hose length you've had that's failed - but I'd advise against using this to create a longer hose.
