Camco 57703 Olympian Propane Regulator with 6 ft Hose

If you're running an Olympian low-pressure propane heater, this is the hose and regulator that feeds it. The Camco 57703 pairs a low-pressure propane regulator with a 6-foot supply hose, so you can tie your Wave 3, Wave 6, or Wave 8 heater into your boat's or RV's propane system and get steady gas to the burner. It's the standard feed part for these heaters, whether you're doing a fresh install or replacing a tired old one.

Here's the thing about these catalytic heaters. They run on low-pressure propane, the same regulated gas that feeds the galley range on most modern boats and campers. This regulator steps tank pressure down to that low-pressure standard so the heater's platinum pad lights and holds a clean flame. One detail that matters at install time: this is a horizontal-mount regulator. Keep it level. Tilt it and the diaphragm can stick, which shows up as inconsistent pressure and a lazy flame.

Note the name. This is the version without a built-in shut-off valve. That's not a flaw, it's just how this part number is configured, and plenty of installs want the shut-off somewhere else in the line anyway. But you do need a way to isolate the gas. We always add a dedicated shut-off valve at the tank or a bulkhead so you can cut propane to the heater without touching the rest of the system. On a boat that's not optional. ABYC gas standards expect an accessible shut-off, and it's just good practice.

The 6-foot hose gives you enough reach to route from a locker or a supply tee to a wall-mounted heater without a lot of slack to manage. On sailboats in the 30 to 35 foot range, that run often threads through a tight lazarette or past a bulkhead. Watch for chafe anywhere the hose crosses an edge or a penetration. A little split-loom or a proper grommet at each pass-through keeps the jacket from wearing through over a season or two of vibration and movement.

A quick word on the heaters this feeds. The Olympian Wave line uses a platinum catalytic pad that burns propane flamelessly and quietly, which is why so many cruisers and RVers reach for them for overnight heat. The Wave 6 tops out around 6,000 BTU, with the Wave 3 sized below it and the Wave 8 above. None of these heaters ship with a shut-off in the gas line, so a feed hose and a separate valve are just part of doing the install right. This 57703 covers the feed side for the low-pressure versions across the range.

Installation is straightforward for anyone comfortable working with propane, but respect the fuel. Shut the tank off before you start. Connect the regulator inlet to your low-pressure supply, route the hose to the heater's inlet fitting, and snug every connection with gas-rated sealant on the threads. Then leak-test with soapy water at every joint before you light anything. If you see bubbles, back off and reseat the fitting. When it's tight and the flame lights clean and blue, you're done.

If you're on salt water, keep an eye on the regulator. Salt air is hard on the diaphragm, and a failing one usually announces itself with a yellow, sooty flame instead of the clean blue you want. Check the hose-end fittings once a season too. Vibration works them loose over time, so a quick torque check and fresh gas-rated sealant on the threads goes a long way toward a leak-free connection you can trust.

Who's this for? Anyone with an Olympian low-pressure heater who needs the correct feed hose and regulator. It's a low-pressure part, so it pairs with the Wave-series heaters and other low-pressure Olympian units. It won't work on a high-pressure setup without the right regulator, so match your system before you order. Get it right and your heater runs the way it should all winter long.
