What's the maximum temperature it can handle?

probably more than you can generate..I use for my dryer and it works fine. Even on high heat for max drying.

Is this hose water tight.

It should be air tight but these kinds of hoses are somewhat fragile and thin. And it would not be difficult to acdcidentally punch a hole in the side of it. I wrapped mine with heavy packing tape to make it a little more durable.

can this be used in the bathroom vent fan that draws out moisture?

Hi Jerilynn,Yes, this aluminum duct will work well with the bathroom vent exhaust fan. This package contains 25 ft of ducting when fully extended, so you'll need to cut it to your length with a pair of metal snips (easy to do). Please make sure that you are buying the correct diameter of the ducting that would fit your vent fan, they typically come in 4 inch and 6 inch diameter.Best regards,TerraBloom

Can I use this to vent exhaust from natural gas water heater?

No, you need a rigid metal pipe.
