High-pressure 30 PSI single-stage propane regulator for outdoor cookers, turkey fryers, smokers, and other high-pressure appliances. 1/4" FNPT inlet x 1/4" FNPT outlet. Vertical mount. Overpressure protection. UL and CSA listed. No shut-off valve. Not approved for permanent RV installation.
The Cavagna 91-A-490-0002 is a single-stage high-pressure propane regulator — built for applications that require a PSI-level output rather than the low water column pressure used by standard RV and household propane appliances. Where low-pressure regulators deliver 11" WC (roughly 0.4 PSI) for furnaces, ranges, and water heaters, this regulator delivers 30 PSI — the output level required by high-BTU outdoor burners, turkey fryers, propane smokers, wok burners, and similar high-pressure cooking equipment.
From Cavagna Group — the same OEM propane regulator supplier behind many factory-installed RV units. The 91-A-490-0002 is a single-stage design in a compact vertical-mount body. 1/4" FNPT on both inlet and outlet. Overpressure protection device limits environmental propane release to less than 2 PSI in the event of regulator malfunction. UL and CSA listed. 60-month limited warranty.

High pressure (this regulator — 30 PSI): For appliances specifically designed for high-pressure propane input — outdoor turkey fryers, propane smokers, large wok burners, high-BTU outdoor cookers. These appliances have their own built-in pressure management and require 10–30+ PSI input. Low pressure (11" WC / ~0.4 PSI): For standard RV and household propane appliances — furnaces, water heaters, ranges, stoves, refrigerators. These require the stable low-pressure output of a two-stage regulator. Using a high-pressure regulator on a low-pressure appliance can damage it or create a hazardous condition. Always confirm your appliance's required inlet pressure before selecting a regulator.
The 91-A-490-0002 delivers 30 PSI — far higher than the 11" WC (~0.4 PSI) required by standard RV propane appliances. Do not connect this regulator to RV furnaces, water heaters, ranges, or other low-pressure appliances. It is also not approved for permanent RV installation. For RV system regulators, see the Cavagna 52-A-490-0018 two-stage low-pressure regulator.
