Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 2 November 2026). A dash means the listing states no figure for that column.

How the picks are scored

Each regulator is scored on performance, build, value, safety and warranty. A UL or CSA listing earns safety points, and excess flow protection and an automatic shut-off valve earn more. A stated warranty term earns warranty points; a regulator with no stated term scores nothing there.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

The 5 propane regulator listings in this guide all state a hose or pigtail length, and 3 state a BTU figure, but only 2 state a warranty term and 2 state a UL or CSA listing. Two are dual-tank auto changeover kits for RVs, and 1 is an adjustable high-pressure regulator with a stated 0-20 PSI range.

Buying guide: best propane regulator for small tank

BTU: match the regulator to the appliance

Grills, heaters and RV furnaces draw different amounts of gas. The listings here state 80, 000 BTU at the low end and 345,200 BTU at the high end, and 2 state no BTU figure at all. Match the rated BTU to the appliance, and check the appliance manual for the pressure it needs.

Hose length and fittings

Hose lengths here run from 3 ft to 4 ft, with pigtails of 12 inches and 18 inches on the dual-tank kits. Check the tank connection before ordering: QCC-1 type-1 on the single-tank regulators, and 1/4-inch SAE inverted flare inlets with a 3/8-inch NPT female outlet on the changeover kits.

Single tank or dual tank

A single-tank regulator feeds a single cylinder. The Flame King and PYXGLAQ kits connect 2 tanks and switch from the primary to the reserve when the primary runs empty, so a cylinder can be removed for refill without interrupting the supply. A mini propane tank pairs with a single-tank regulator for a grill or heater.

Adjustable or fixed

Only 1 regulator here states an adjustable range: the GasOne 2109-RED, adjustable from 0-20 PSI with a red knob. The Flame King is factory set at 11WC. The PYXGLAQ listing says the pressure can be adjusted but states no range, and the other listings state no adjustment.

Safety listing and leak checks

A UL or CSA listing is the checkable safety mark here: the Flame King is UL Listed and the PYXGLAQ is CSA certified. The PYXGLAQ adds excess flow protection, an automatic shut-off valve and a gauge that the listing says can detect leaks. Check the connections for leaks before the first use, and follow the appliance manual.

A propane garage heater is among the appliances these regulators feed, alongside grills, fire pit tables and RV furnaces.

Garage Fit Check

• Tank size: the Blackstone adapter fits a 20 lb tank, while the Flame King and PYXGLAQ kits connect 2 tanks for RVs, vans and trailers.
• Hose: hoses here run 3 ft to 4 ft, with 12-inch and 18-inch pigtails on the changeover kits, so measure the run from tank to appliance before the first job.
• Fittings: check the tank connection matches, QCC-1 type-1 on the single-tank regulators and 1/4-inch SAE inverted flare inlets with a 3/8-inch NPT female outlet on the changeover kits.
• Check before the first job: the PYXGLAQ indicator changes color when a tank is depleted, so check the indicator before the first use.
• Storage: keep the Teflon tape and wrench from the PYXGLAQ kit with the regulator, and keep pigtails and hoses where they will not kink.

FAQ: garage tools

How much is a regulator for a propane tank?

The listings used here state no prices. What differs is the type: a single low-pressure regulator with a 3 ft hose, an adjustable high-pressure regulator with a 4 ft hose, or a dual-tank auto changeover kit with a gauge and 2 hoses.

What is a propane tank regulator?

A regulator sits between the tank and the appliance and drops tank pressure to the level the appliance uses. The Flame King is factory set at 11WC, and the GasOne 2109-RED adjusts from 0-20 PSI with a red knob.

What is a propane regulator and why do you need one?

A propane regulator controls the gas pressure from the tank to the appliance so the burner gets a steady feed. The listings here describe 2-stage designs that maintain constant gas pressure under changing demand and conditions.

Some are. The GasOne 2109-RED adjusts from 0-20 PSI with a red knob, and the PYXGLAQ listing says the pressure can be adjusted but states no range. The Flame King is factory set at 11WC, and the other listings state no adjustment.

What pressure does a propane regulator put out?

It depends on the regulator. The Flame King is factory set at 11WC, the GasOne 2109-RED adjusts from 0-20 PSI, and the GasOne 2106 is a low-pressure regulator. The Blackstone and PYXGLAQ listings state no output pressure figure.
