Want to have tanks I can handle. Will this work with two 40pound bottles?** A: Yes it can. Open both bottles and it will pull from one until empty and then switch to the other one when needed. I can run my stove, camper heater and hot water heater at the same time from my 2 20lb bottles. **Q: I bought this to use with a heater buddy in a small cabin. While trying to find a fitting or connecting hose I was told the two are not compatible.** A: I don’t know about the heater buddy connection but the unit should hook to tanks just fine **Q: Will this work for a 55000 btu propane wall furnace?** A: Yes But it’s made with two outlets. You will have to plug one as needed. Or by a single regulator. **Q: Is this unit compatible with Gaspro Type 1 gauge?** A: If the gauge is designed for propane then yes. ## Frequently Bought Together - Flame King (KT12ACR-2a) 2-Stage Auto Changeover LP Propane Gas Regulator With Two 12 Inch Pigtails For RVs, Vans, Trailers - Flame King Dual RV Propane Tank Cylinder Rack for RVs and Trailers for 20lb Tanks - KT20MNT (Tanks Sold Separately) - Flame King Dual 20LB LP Propane Tank Light Plastic Heavy Duty Cover for RV, Travel Trailer, Camper - Black --- ## 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.pt/products/303628268-2-stage-auto-changeover-regulator-with-pigtails](https://www.desertcart.pt/products/303628268-2-stage-auto-changeover-regulator-with-pigtails) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-08*
