Flame King Gas Cylinder Pressure Regulator

Flame King Gas Cylinder Pressure Regulators: Precision LP Control Where It Counts

When it comes to safely managing propane flow from cylinder to appliance, the pressure regulator is one of the most critical components in the system. Flame King has built a strong reputation as a market leader in propane storage and accessories, and their gas cylinder pressure regulators reflect that same commitment to engineered reliability. Whether you're fueling an RV, a food truck, a generator, or a campsite setup, Flame King regulators are designed to keep LP gas flowing safely and consistently under real-world conditions.

What Sets Flame King Regulators Apart

Built on a foundation of innovation and integrity, Flame King's products are engineered for performance, safety, and longevity. This philosophy carries directly into their pressure regulator lineup. Two standout features define their approach:

• UL Listing: Flame King's regulators carry UL certification, with inlets sized at 1/4" SAE inverted flare and outlets at 3/8" NPT female pipe thread, and ratings reaching up to 345,200 BTU.
• Dual-Stage Pressure Reduction: The 2-Stage Propane Gas Regulator allows you to control propane to match the pressure required for specific propane devices; the second stage further controls pressure to safely meet the supply needed for the appliance in use.
• Auto-Changeover Technology: The Auto-Changeover LP Regulator allows you to hook up two propane tanks, automatically switching over to the second tank once the first one runs out.
• Safety-First Assembly: Regulators are assembled using high-strength thread-locker on adapter connections where pigtails attach — an intentional safety measure designed to keep critical fittings secure and prevent gas leaks during use.

Key Product Lines

Flame King offers regulators suited to a range of propane setups. Their 2-Stage LP Propane Gas Regulator (Model G2R150B) is a workhorse unit: it delivers an outlet pressure of 11-inch water column with a BTU/HR capacity of 150,000, and is great for larger RVs, food trucks, campervans, and other large vehicles with appliances that require high BTU outputs. Made from heavy-duty aluminum material, it ensures connections with the tank are secure and leak-free.

Their Auto-Changeover Regulator (Model ACR-2) is purpose-built for dual-tank RV systems. The double-stage design maintains constant gas pressure under changing demand and conditions, with the regulator factory set at 11" WC (water column) and a lockout pressure of up to 14.9" WC.

For portable and low-pressure applications, Flame King also offers regulator assemblies with quick-connect fittings. Featuring a QCC1 Type-1 tank connector and Model 250 quick disconnect fitting, these assemblies allow you to connect or disconnect your propane cylinder and appliance in just seconds. They are compatible with OPD valve cylinders including 5 LB, 10 LB, 20 LB, 30 LB, and 40 LB tanks.
