Two-stage low-pressure propane regulator for RV, camping, outdoor cooking, and indoor propane appliances. Vertical vent. 1/4" FPT inlet x 3/8" FPT outlet. Stable 11" WC output. 160,000 BTU/hr. 0.92 lbs. For use with indoor/outdoor propane appliances.
The Mr. Heater F273763 is a two-stage low-pressure propane regulator for use with propane-fueled indoor and outdoor appliances — RVs, campers, outdoor cooking setups, Mr. Heater portable heaters, and other standard low-pressure propane applications. Manufactured by Enerco Group / Mr. Heater, a leading name in portable propane heating equipment since 1957.
The two-stage design delivers the same benefit as other two-stage regulators in this category: the first stage reduces the variable, high tank pressure to an intermediate level, and the second stage further reduces it to the stable 11" WC delivery pressure that all standard low-pressure propane appliances require. The result is more consistent appliance performance — especially noticeable when multiple appliances are running simultaneously or as the propane tank empties and tank pressure drops. Vertical vent orientation. 1/4" FPT inlet x 3/8" FPT outlet. Weighs just 0.92 lbs. Assembled in USA.

A single-stage regulator reduces tank pressure directly to delivery pressure — but because tank pressure varies (higher when full and cold-soaked, lower as it empties or in cold weather), the outlet pressure can fluctuate slightly with it. A two-stage regulator adds an intermediate pressure step between tank and appliance. The first stage normalizes the variable tank pressure to a stable intermediate level; the second stage reduces that to the final 11" WC. The result is a consistent outlet pressure even as tank fill level and ambient temperature change. For single-appliance, occasional use, single-stage is often sufficient. For multiple simultaneous appliances or where consistent flame height/heat output matters, two-stage is the better choice.
All two-stage, low pressure, 1/4" FPT x 3/8" FPT, 11" WC — key differences: Mr. Heater F273763 (this item): • 160K BTU, vertical vent, 0.92 lbs., no shut-off valve • General purpose — RV, camping, outdoor, indoor appliances Suburban LP-R524V: • 160K BTU, vertical vent, integrated shut-off valve, excess flow protection, overpressure protection, RVIA approved Suburban LP-R524H: • Same as LP-R524V but horizontal vent Choose the Suburban units for permanent RV installation where RVIA approval and integrated safety features are required. The Mr. Heater F273763 is well-suited for portable and camping applications or as a general replacement.
