Single-stage design, and it ships without a hose or shut-off valve on purpose so you can spec marine-grade fittings for your boat. A smart upgrade if you're tired of feeding 1 lb disposable cylinders.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Magma Crossover Single Burner Firebox ships ready to run off a 1 lb disposable propane cylinder. That's fine for a weekend. But if you cook most nights aboard, those little green bottles add up fast, and you're always hunting for the next one. This regulator is how you cut the cord. It steps a bulk propane tank down to the low pressure the firebox burner wants, so you can run the whole Crossover cook system off the same refillable tank you already carry for the grill or the cabin stove. One tank, one refill, and you're cooking for the whole trip instead of counting bottles.\u003c\/p\u003e\n\u003cp\u003eA few things to know up front, because this is a without part on purpose. Without shut-off valve. Without hose. Single stage. That means you supply the LP hose, marine-grade and gas-rated, not the cheap pigtail, and you rely on your tank's own valve to shut off the gas. Magma builds it this way so you can spec the hose length and fittings that suit your boat, whether the tank lives in a cockpit locker two feet away or in a vented propane box up on deck.\u003c\/p\u003e\n\u003cp\u003eThis regulator plays nicely with the aluminum LP tanks most 25 to 35 foot boats carry, anywhere in the 5 to 20 lb range. If you're still running an older steel tank, keep an eye on the inlet fitting. Salt air and steel don't get along, and a corroded inlet is both a performance and a safety problem. Aluminum is the way to go out on the water. Whichever tank you run, confirm its valve threads match the hose you buy, since the hose isn't in the box with this regulator.\u003c\/p\u003e\n\u003cp\u003eWe've seen a few of these installed wrong, so here's the short version. Mount the regulator upright, and keep it above bilge level. Water sitting on the diaphragm is what kills these, and a soaked regulator is a regulator you're replacing. Use a proper gas-rated thread sealant on the pipe threads, not PTFE tape, and snug the fittings so engine and sea vibration don't back them out over a season. Then leak-check every joint with soapy water before you cook. Every time.\u003c\/p\u003e\n\u003cp\u003eSingle-stage regulators are simple and dependable, which is exactly what you want on a boat. The trade-off is that output pressure drifts a little as the tank cools and the level drops. So on a cold morning with a near-empty tank, you might notice the flame isn't quite as tall as usual. Warm the tank, or just keep it topped up, and it's a non-issue for normal cooking. For the low-pressure Crossover burner, this regulator is a solid match. It's the kind of part you install once and forget about.\u003c\/p\u003e\n\u003cp\u003eThe Crossover system is modular by design. One firebox, and you swap between a grill, a griddle, a plancha, or a pizza oven top depending on what's for dinner. Feeding that firebox from a bulk tank through this regulator means you can cook a full spread without babysitting a disposable cylinder that runs dry halfway through. Out in the salt, plan on swapping the regulator every few seasons even if it still seems fine. UV and salt crust crack the housing and stiffen the diaphragm over time, and a forty-dollar part is cheap insurance against a gas leak.\u003c\/p\u003e\n\u003cp\u003eOne more word on safety, because it's propane on a boat and that deserves respect. Keep the tank in a vented, dedicated locker that drains overboard, never inside the cabin. Route the hose so it can't chafe against a bulkhead or a sharp edge. And shut the gas off at the tank valve when you're done cooking, since this regulator doesn't have its own shut-off. Do those three things and a bulk-tank setup is every bit as safe as the disposable bottles, and a lot less hassle. Bottom line: if you're a Crossover owner ready to move off disposable cylinders and onto a refillable tank, this is the piece that gets you there.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eSingle-stage low-pressure regulator matched to the Crossover firebox burner\u003c\/li\u003e\n  \u003cli\u003eSteps a bulk propane tank down to the low pressure the single burner needs\u003c\/li\u003e\n  \u003cli\u003eShips without a shut-off valve or hose so you spec marine-grade fittings for your boat\u003c\/li\u003e\n  \u003cli\u003eMade for the Magma Crossover Single Burner Firebox gas inlet\u003c\/li\u003e\n  \u003cli\u003eWorks with refillable 5, 10, and 20 lb LP tanks, moving you off 1 lb disposables\u003c\/li\u003e\n  \u003cli\u003eCompact regulator body mounts upright above bilge level for a clean, dry install\u003c\/li\u003e\n  \u003cli\u003eGenuine Magma replacement part, MPN 10-775\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Magma reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes this regulator include a hose?\u003c\/summary\u003e\n    \u003cp\u003eNo. It ships without a hose on purpose so you can pick the right marine-grade, gas-rated LP hose and length for your boat.
