It steps your cylinder pressure down to a steady 11 inches water column and holds it there, so your furnace, water heater, and cooktop all run even. Rated at 160,000 BTU per hour with a horizontal POL mount, it's a straightforward replacement for a tired or single-stage regulator.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Camco 59333 is a two-stage propane regulator built for RV LP-gas systems, and it does one job really well. It takes the high, variable pressure sitting in your propane cylinder and steps it down to a steady 11 inches of water column at the outlet. That's the pressure your furnace, water heater, cooktop, and fridge all expect to see. Get that number wrong and appliances run rich, pilot lights drop out, and you spend the weekend chasing gremlins instead of enjoying the trip.\u003c\/p\u003e\n\u003cp\u003eTwo-stage is the part that matters here. A single-stage regulator drops tank pressure to appliance pressure in one step, which works fine until the weather turns cold or the tank runs low and the pressure starts wandering. This unit does it in two stages instead. The first stage knocks the high cylinder pressure down to an intermediate level, and the second stage holds the final outlet at that steady 11 inches water column no matter what the tank is doing. So your flames stay even on a frosty morning with a nearly empty bottle, which is exactly when a single-stage regulator starts to struggle.\u003c\/p\u003e\n\u003cp\u003eCapacity is 160,000 BTU per hour. That's enough headroom to run a typical RV's full propane load at once, the furnace, the water heater, the range, and an absorption fridge, without starving anything. On most travel trailers and motorhomes you'll never come close to maxing it out, and that's what you want. A regulator should have margin to spare.\u003c\/p\u003e\n\u003cp\u003eThe connections are standard RV plumbing. The inlet is a Prest-O-Lite (POL) fitting, the left-hand-thread connection that threads into the service valve on a standard LP cylinder, with a 1\/4 inch NPT inlet port behind it. The outlet is 3\/8 inch NPT. The body mounts horizontally, so it drops right into the low-profile regulator compartments and tongue-mounted tank setups where vertical clearance is tight.\u003c\/p\u003e\n\u003cp\u003eCold-weather performance is where a two-stage regulator really earns its spot. When you're camping in the shoulder seasons and the overnight temperature drops, propane pressure inside the tank drops right along with it. A single-stage unit can't always keep up, and you'll notice it as a weak furnace flame at the worst possible time. The second stage on this regulator absorbs that swing and keeps the outlet locked at 11 inches water column, so the furnace that kept you warm at bedtime is still doing its job at 4 in the morning. If you camp late into the fall or head out early in spring, that consistency is the whole point.\u003c\/p\u003e\n\u003cp\u003eA couple of things to know before you order. This regulator ships without a shutoff valve and without a hose. That's normal for a replacement regulator. It's meant to tie into the plumbing and pigtail you already have, or into new lines you're running to spec. If you're building a system from scratch you'll want to add an appropriate LP hose or pigtail and, depending on your setup, a manual shutoff at the tank. And because it's a horizontal-mount unit, install it the way the body is designed to sit so the vent stays protected and the diaphragm works the way it should.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone replacing a tired or failed regulator on an RV, travel trailer, or fifth wheel, and anyone upgrading a single-stage setup to proper two-stage regulation. If your appliances have been running unevenly, if your furnace short-cycles in the cold, or if you just don't know how old the regulator on your rig is, replacing it is cheap insurance. Propane regulators are wear items. They don't last forever, and a failing one is both a comfort problem and a safety one.\u003c\/p\u003e\n\u003cp\u003eIt's a Camco, so it's built to the standard you'd expect from a company that's been making RV gear since 1966. Straightforward to install if you're comfortable working on LP-gas lines, and if you're not, this is a job worth handing to a tech. Get the connections tight, leak-check with soapy water before you light anything, and you're set for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eTwo-stage regulation delivers a steady 11 inches water column outlet pressure for even appliance flames\u003c\/li\u003e\n  \u003cli\u003e160,000 BTU\/hour capacity covers a full RV load: furnace, water heater, range, and refrigerator\u003c\/li\u003e\n  \u003cli\u003ePrest-O-Lite (POL) inlet threads onto the service valve of a standard LP cylinder\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT inlet port and 3\/8 inch NPT outlet match common RV gas-line fittings\u003c\/li\u003e\n  \u003cli\u003eHorizontal mount body fits low-profile regulator compartments and tongue-mounted tank setups\u003c\/li\u003e\n  \u003cli\u003eTwo-stage design holds outlet pressure steady as the tank empties or the weather turns cold\u003c\/li\u003e\n  \u003cli\u003eApproved for RV use for code-compliant LP-gas installations\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 Camco 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\u003eWhat does a two-stage propane regulator do?\u003c\/summary\u003e\n    \u003cp\u003eIt steps your cylinder's high pressure down to appliance pressure in two stages instead of one.
