Camco 59103 Propane Supply Splitter with 3 Ports and 12 ft Hose

The Camco 59103 solves a common propane headache. You've got one tank, but you want to run more than one appliance off it. This brass tee splits a single LP supply into multiple feeds, and it ships with a 12-foot hose so you've actually got the reach to plumb in that second appliance without fighting the layout.

Here's how the three ports break down. The inlet is a female Prest-O-Lite (POL) fitting with a male ACME thread, so it threads onto a standard 20 lb refillable cylinder the way you'd expect. From there you get an excess flow soft nose POL port and a 1-inch-20 male throwaway cylinder thread port. The soft nose POL gives you a second seal and an excess flow feature that chokes off the gas if a downstream line lets go. The 1-inch-20 male port matches the thread on a 1 lb disposable bottle, so an appliance that normally screws onto a small green camp cylinder can run off your big tank instead. More cook time, fewer little bottles in the trash.

We see this setup on boats with a propane locker feeding a galley stove plus a cabin heater, and on RVs where folks want to add an outdoor grill or a fire pit to the existing supply. The idea is the same either way. One tank does the work of two or three, and you're not swapping bottles mid-meal. The 12-foot hose is long enough to reach a grill mounted on the rail or a heater across the cockpit, and short enough that it isn't a coil of slack you're tripping over.

A couple of honest notes. This is a supply splitter, not a regulator. It splits and routes gas, but each appliance still needs whatever regulator it was built to use. And that third port with the throwaway cylinder thread doesn't get used on every install. Plenty of folks run just the inlet and the POL port and leave the small-bottle port capped, and that's fine. Fewer connections means fewer places to check for leaks, so if you don't need it, don't feel like you have to fill every port.

Install is straightforward if you respect propane. Thread the inlet onto your cylinder, snug the fittings, then bring them up to spec with a wrench. Don't gorilla it and don't leave them finger tight either. Once everything's connected, brush a little soapy water on every joint and open the gas. If you see bubbles, you've got a leak, so back off and reseat that fitting. It's a two-minute test that saves you a lot of grief. Keep the hose clear of sharp edges and hot surfaces, and if it runs any distance, secure it every foot and a half so it can't chafe.

One thing worth knowing up front. This tee feeds an excess flow valve, and that valve is doing its job when it trips. If you open a second appliance too fast, or you've got a leak downstream, the flow can shut itself down. The fix is simple. Close everything, let the valve reset, then open your appliance valves slowly, one at a time. It's not a defect. It's the safety feature working the way it should. Keep your total load reasonable too. Stack too many high-BTU appliances on one tank and you'll ask more of the regulator than it wants to give, especially on a cold morning.

For anybody running propane on the water or at the campsite, the 59103 is a clean way to get more out of a single tank. Solid brass, a real excess flow port, and enough hose to actually reach the appliance you're adding. It's the kind of part you thread on once and mostly forget about, which is exactly what you want from anything carrying gas.
