The dual-stage design reduces pressure fluctuation as tank pressure changes, while the POL inlet and 3\/8\"-18NPT outlet give secure connections to 100 lb or ASME tanks and standard RV gas lines. Constructed from heavy-duty aluminum with solid brass fittings and a top vent, it prioritizes durability and safe venting in horizontal installations.\n\n\u003ch3\u003eHow does a two-stage regulator improve propane performance?\u003c\/h3\u003e\n\u003cp\u003eA two-stage regulator stages pressure reduction across two diaphragms so downstream pressure stays closer to the target even as tank pressure rises or falls. This results in smoother appliance operation and fewer nuisance shutoffs when multiple burners or heaters run simultaneously.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces pressure fluctuation under variable demand\u003c\/li\u003e\n  \u003cli\u003eDelivers consistent 11-inch water column outlet pressure\u003c\/li\u003e\n  \u003cli\u003eMakes high-BTU appliances run more reliably\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this regulator fit my RV, trailer, or generator setup?\u003c\/h3\u003e\n\u003cp\u003eThe Flame King regulator uses a POL (inlet) connection compatible with common 100 lb and ASME propane tanks and a 3\/8\"-18NPT outlet to mate with standard RV gas lines or manifolds.

Choose it when you need a durable, higher-capacity replacement that maintains steady gas pressure across changing tank conditions and heavy appliance loads. Always follow local codes and, if unsure, have a qualified technician install and leak-test the regulator before use.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this regulator compatible with 100 lb propane tanks?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
