The old unit was leaking when tank valves where open. They are only designed to last 10 years and I got 19.. ## Frequently Bought Together - Flame King KT18ACR6 2-Stage Auto Changeover LP Propane Gas Regulator with Two 18-inch Pigtails for RVs, Vans, Trailers - Flame King Thermo Plastic Hose Assembly For LP and Natural Gas, 48 Inch, 3/8 Inch ID - 100383-48, Black - Vanguard Sealants Teflon Gas Pipe Thread Sealant - PTFE Yellow Teflon Tape for Gas Fittings - 260" Length Pipe Thread Tape 1/2 inch High Resistance Leak Prevention - Propane Thread Seal Tape --- ## 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.co.uk/products/534594560-2-stage-auto-changeover-regulator-with-pigtails](https://www.desertcart.co.uk/products/534594560-2-stage-auto-changeover-regulator-with-pigtails) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
