Consistent gas pressure to every appliance in your RV starts with a properly sized, properly staged regulator. The Camco 59312 integrates both the first and second regulation stages into a single compact unit, stepping high tank pressure down to a steady 11 inches of water column (WC) for safe, reliable delivery to your furnace, water heater, range, and refrigerator -- all at up to 160,000 BTU per hour.
Single-stage regulators can produce pressure fluctuations as tank supply pressure changes -- especially as a tank empties or temperatures drop. A two-stage design solves this by handling the pressure drop in two controlled steps. The first stage reduces high tank pressure (which can exceed 200 PSI when warm) to an intermediate level, and the second stage trims that down to the appliance-ready 11 in. WC delivery pressure. The result is noticeably steadier flame height and more even heat output, which matters most when running multiple appliances simultaneously.
The 59312 mounts in the vertical orientation required by most standard RV LP compartments and dual-cylinder pigtail setups. Its compact body fits where larger combination units will not, and the straightforward 1/4 in. POL-side inlet and 3/8 in. FPT outlet thread directly into common RV LP piping without extra adapters in most installations.
First and second stages are built into one housing -- no separate high-pressure regulator needed upstream.
Handles the combined load of furnace, range, water heater, and refrigerator in most RV configurations.
Delivers the standard appliance pressure required by virtually all RV LP appliances sold in North America.
Certified to CSA safety standards for LP gas equipment -- required by most RV manufacturers and campground inspections.
Two-stage regulators are the correct choice for any RV with more than one LP appliance or a supply line run longer than a few feet. They are standard equipment on most Class A, Class C, and fifth-wheel coaches from the factory, and are the recommended replacement type by the RV Industry Association when the OEM unit fails or is upgraded. If your current rig has a single-stage regulator and you notice flame fluctuation, yellow flame tips, or inconsistent appliance performance, upgrading to a two-stage unit like the 59312 is the most effective fix.
The 59312 is designed for vertical mounting with the vent pointing downward -- this is the standard orientation for most OEM LP compartment installations and dual-cylinder changeover setups. Confirm the vent is not obstructed after installation; a blocked vent can cause regulator lock-up or over-pressure downstream.
