Is this safe to vent a portable ac? ac's can get really hot.

I've never owned a portable AC. If there is a 4" circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole.

anyone use this for garage auto exhaust tube?

I am currently using this to exhaust the air in my wood shop

Is this suitable for marine use?

No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement). If you want to use it as a duct for a bilge blower, I would say go ahead and use it. If you are concerned about fire retardancy, I suggest you contact the seller first.

Proper stuff, sorted my dryer out!

Finally got round to replacing the rubbish old ducting on me tumble dryer, the old one was practically made of cobwebs and hope. This AC Infinity stuff is a different kettle of fish altogether! It's really sturdy, you can tell its got those four layers they talk about. Was a bit of a wrestle getting it connected up, like trying to tame a shiny silver python, but once it was on with a couple of jubilee clips, it felt solid. The 8 feet length was more than enough, had a bit to spare. Dryer seems to be working more efficient now too. Well chuffed.

Large Flexible Ducting

Bought this so that I could install some AC units that require large holes through the wall in a slightly different way to the manufacturers instructions. This ducting is perfect, I cut it to the desired length with a sharp knife and wire cutters, attached both ends with jubilee clips and they work a treat. This ducting was absolutely perfect for what I needed it for and delivered super fast by Amazon
