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. **Q: anyone use this for garage auto exhaust tube?** A: I am currently using this to exhaust the air in my wood shop **Q: Is this suitable for marine use?** A: 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. ## Frequently Bought Together - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity CLOUDLINE PRO S4, Quiet 4” Inline Duct Fan with Speed Controller – EC Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Air Carbon Filter 4" with Premium Australian Virgin Charcoal, for Inline Duct Fan, Odor Control, Hydroponics, Grow Rooms --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/153233209-ac-infinity-flexible-4-inch-aluminum-ducting-8-feet-long](https://www.desertcart.hr/products/153233209-ac-infinity-flexible-4-inch-aluminum-ducting-8-feet-long) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-09*
