Camco 10389 Propane Pressure Test Kit, 0-35 WC with 30-Inch Hose
Camco 10389 Propane Pressure Test Kit, 0-35 WC with 30-Inch Hose — Product description
The Camco 10389 Propane Pressure Test Kit tells you exactly where your LP system stands. It reads gas pressure on a clean 0 to 35 inch water column scale, so you can check a regulator's output and hunt down leaks without guessing. Gauge, 30 inch hose, brass tap fitting, and a hard case, all in one kit.
Every propane system on an RV or a boat lives or dies on pressure. Too high and you risk unsafe burners and stressed fittings. Too low and your stove won't light and your furnace runs weak. The Camco 10389 Propane Pressure Test Kit is the tool that tells you exactly where you stand. It reads gas system pressure on a clean 0 to 35 inch water column scale, so you can check a regulator's output and hunt down leaks without guessing.
If you've never worked with water column before, here's the short version. Low-pressure propane isn't measured in PSI like a tank. It's measured in inches of water column, the same way a manometer works. Most RV and marine LP systems run right around 11 inches WC at the appliance. This gauge covers 0 to 35 inches, so you've got plenty of range to see a properly set regulator, catch one that's drifted high, or spot a system that's barely holding pressure at all. The face is easy to read, which matters when you're crouched in a propane locker or under a dinette with a flashlight in your teeth.
Leak testing is where this kit really earns its spot in the toolbox. You pressurize the system, watch the needle, and wait. If the pressure holds steady, you're tight. If it creeps down, you've got a leak somewhere and it's time to start chasing fittings with soapy water. It's a simple test, but it's the one that keeps propane where it belongs, inside the lines. Anyone who installs an appliance, swaps a regulator, or opens up a gas line should be running this test before they call the job done.
Setting a regulator is the other job this gauge handles well. When you install a new two-stage regulator or replace an old one, the outlet pressure needs to land in the right window for your appliances to burn clean. Too rich and you get sooty flames and lazy ignition. Too lean and burners lift and sputter. With the 10389 threaded in, you can read the actual delivered pressure and confirm the regulator is doing its job before you trust it to run a cooktop or a heater all season.
Camco built the kit to be complete right out of the case. You get the gauge, a 30 inch hose, and a brass pressure tap fitting that ties into your system's test port. The 30 inch hose gives you room to route around tight spots so the gauge sits where you can actually see it. Everything stows in a hard case, so the gauge doesn't get banged around in a storage bay between jobs. Pull it out, thread it in, run your test, and pack it back up.
This is a tool for RV owners, boat owners with propane galleys or cabin heaters, and the techs who service both. It's not a toy and it's not a one-time gadget. Propane systems need checking after installs, after a season of vibration on the road or the water, and any time something smells or lights wrong. Keep this in the kit and you'll always have a straight answer instead of a guess.
A quick word on care. This is a mechanical gauge, so treat it like one. Don't over-torque the brass fitting, just snug it up and let the threads seal. Keep the hose out of sharp bends that could kink and throw off a reading. And store it back in its case when you're done. Handled right, a gauge like this lasts for years and stays accurate job after job. That's the whole point of buying a real test kit instead of eyeballing a flame and hoping.

Frequently asked questions
What does 0-35 WC mean on this gauge?
WC stands for water column, the unit used to measure low-pressure propane. This gauge reads from 0 to 35 inches of water column, which covers the normal operating range of RV and marine LP systems with room to spare for high-side checks.
What's included in the kit?
You get the pressure gauge, a 30 inch hose, a brass pressure tap fitting, and a hard carrying case. It's ready to use right out of the box.
What is this kit used for?
Two main jobs. First, testing a propane system for leaks by pressurizing it and watching whether the needle holds. Second, checking and setting regulator output pressure so your appliances burn clean and safe.
Can I use it on both RV and boat propane systems?
Yes. Low-pressure propane works the same way on an RV as it does on a boat with a propane galley or cabin heater. The brass tap fitting connects to a standard test port on either.
How long is the hose?
The hose is 30 inches, which gives you room to route around tight fittings and position the gauge where you can actually read it.
How do I test for a leak with it?
Connect the tap fitting to your system's test port, pressurize the lines, and watch the gauge. If the pressure holds steady, the system is tight. If the needle creeps down, you have a leak to track down, usually with soapy water at the fittings.
What kind of fitting connects to my system?
It uses a brass pressure tap fitting that threads into the test port on your propane system. Snug it up hand-tight plus a little so the threads seal without over-torquing the brass.
What pressure should my propane system read?
Most RV and marine appliance systems are set around 11 inches of water column, but always confirm the target against your regulator and appliance specs. This gauge lets you read the actual delivered pressure so you can set it correctly.
