Camco 57721 Olympian Propane Regulator, 12 ft Hose

The Camco 57721 is the low-pressure regulator and hose assembly that feeds an Olympian propane heater from your gas supply. If you're running an Olympian low-pressure heater in an RV, a van build, a cabin, or a boat, this is the part that turns bottled propane into the steady, low-pressure gas those heaters are built to burn. You get the regulator and a 12-foot hose in one assembly, so there's plenty of reach between the tank and the heater and nothing extra to source.

The 12-foot hose is the reason a lot of folks pick this one. Twelve feet gives you room to mount the heater on a bulkhead or wall and still run the line back to a propane locker, a bumper-mounted bottle, or a tank tucked under a bench. If your heater and tank sit close together, Camco's 6-foot 57703 covers the same job with less hose to coil and stow. Pick the length that matches your install, not the other way around.

This is a horizontal-mount regulator, and that matters more than it sounds. Mount it so the regulator body sits level and the vent points the way the instructions call for. Low-pressure regulators rely on a diaphragm and a vent to hold output steady, and mounting one off-axis can let it drift or weep gas over time. Get it level, get it horizontal, and it'll hold pressure the way it should.

One thing to know up front. This assembly comes without a shut-off valve, and that's on purpose. A lot of installs already have a valve at the tank or a manifold shutoff feeding the line. If yours doesn't, add a shut-off valve between the tank and this regulator so you can kill the gas without unthreading a fitting. Plenty of van builders and boaters pair it with a manual valve or a 12-volt solenoid for a remote shutoff at the dash or the helm. Do whatever keeps your setup safe and easy to service.

It's built for Olympian low-pressure propane fired heaters, the catalytic and radiant Wave-style units Camco sells for cabins, RVs, vans, and boats. Confirm your heater is a low-pressure model before you order, because a high-pressure appliance needs a different regulator entirely. Match low-pressure to low-pressure and you're set.

Installation is straightforward for anyone who's rigged propane before. Thread the regulator to your supply, run the hose to the heater, and seal every joint with a propane-rated thread sealant, not the plumber's tape meant for water lines. Snug the fittings, then leak-check every connection with soapy water before you light anything. Vibration from a moving rig can loosen a fitting over a season or two, so it's worth a quick re-check each spring when you recommission. A two-minute leak test is cheap insurance.

The hose is flexible enough to route around a corner or through a bulkhead pass-through without kinking, as long as you give it a gentle bend instead of a hard fold. In tight lockers or a cramped van cabinet, coil the extra length loosely rather than crimping it against a panel. A kinked hose starves the heater and stresses the crimp at the fitting, and that's the spot most likely to seep down the road. Route it clean, support it every few feet, and keep it clear of anything hot or sharp.

This is the right part if you're replacing a tired hose, extending your reach with more line, or finishing a fresh Olympian heater install. It's not a universal propane regulator, and it's not meant for high-pressure appliances, a grill on a full 20-pound bottle, or anything outside the low-pressure Olympian family. Stick to what it's built for and it'll run clean and quiet for years.
