Am I missing something?** A: It is a tight fit I used it on mobile home went on fairly easy they do mention in the description it is used for mobile home so I'm not sure if it works on your application or not Hope this helps **Q: can this be made explosion proof with wire clips? planning to use as vent for paint spray booth using flammable paints** A: This is where you get professional advice. Also don’t β€œroll you own” when it comes to explosion proof stuff. There are companies out there that make explosion proof stuff as well as paint booths. Their are various UL and NFPA requirements that have to be met. Look for used equipment, with this economy it is out there. There are ways of saving money, there are parts of this you can DIY, but you need someone who understands the hazards to do this safely. Also, anyone telling you how to do this without seeing what you want to do - does not know what they are doing. **Q: Im making my own welding extractor, do you think that is going to work?** A: Yes, it should work for a welding extractor. Use duct tape between the ducting and the metal clamps to protect the ducting, otherwise the clamps can rip holes in it **Q: Can this replace hvac duct work for a house** A: It will but I'd advise not to. It's not insulated enough. ## Frequently Bought Together - AC Infinity Flexible 12-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust - AC Infinity CLOUDLINE PRO T12, Quiet 12” Inline Duct Fan with Temperature Humidity VPD Controller, WiFi Integrated App Control - Ventilation Exhaust Fan for Heating Cooling, Grow Tents, Hydroponics - EesTeck 2Pcs 12"(Diameter) Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps (289mm-311mm) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/202008950-ac-infinity-flexible-300mm-aluminum-ducting-heavy-duty-four-layer](https://www.desertcart.sg/products/202008950-ac-infinity-flexible-300mm-aluminum-ducting-heavy-duty-four-layer) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-22*
