Low Pressure Propane Gas Regulators - Preset, First Stage, Second Stage, and Twin Stage  

Gas grills up to about 50,000 btu/hr most often use low pressure propane which requires a low pressure propane regulator. Low pressure gas can be natural gas (natural gas normally does not require further pressure regulation), or propane piped into a trailer home or RV, or a conventional home in which the gas has already been adjusted to a 6 ounce (10.5 WC inches) low pressure at the propane source.   Preset low pressure propane regulators are set at 6 ounces.    {Handy conversions:  1" WC = 0.036127 psi , 16 oz. = 1 pound}   We ship everywhere in the world...and the shipping is free to the 48 contiguous US states.


How are the GasHosesandRegulators.com low pressure propane gas regulators any different than what is customarily sold at Home Depot, Lowe's, or from those included as original equipment with most gas grills?    

GasHosesandRegulators.com  sells the M.B. Sturgis brand of low pressure regulators designed with 3/8" ID gas regulator outlets and 3/8" ID grey, AGA-approved gas hoses rather than the customary regulators with 1/4" ID gas outlets and with 1/4" ID black hoses.  The 1/4" ID type are usually found on most backyard gas grills or are offered for sale at the Depots as replacement equipment. A larger gas regulator outlet ID of 3/8", going all the way from the regulator to the appliance permits an amazing increase in delivery of 2.25 times the VOLUME of gas to your appliance!  

These are preset regulators so you can't change the pressure, but you can change the volume of gas available to your appliance if it needs it.  So, if you think your low pressure gas appliance is just not getting enough gas, the problem could be the diameter size of the regulator output and the hose delivering the gas.  A regulator with a 3/8" ID diameter gas regulator outlet and a 3/8" ID grey hose is going to it make a lot more gas available to the appliance.  Upgrade.  Don't starve your grill of fuel!   You still control the amount of gas used in the same manner, i.e., with the gas control knob on your appliance.

Why order a Green Acme tank fitting for your regulator?  

The Green Acme Type 1 tank fitting was made to tighten up clockwise using your hand into the propane tank without the requirement of using a wrench. It will screw into almost any standard propane tank except the very large 100# propane tanks. It was designed with a safety shut-off feature that is a thermally-sensitive sleeve which also will shut the gas off if it senses temperatures above 240°F or detecting excessive gas flow.

The Optional MANC-SS with two 24" high pressure thermoplastic hoses with a protective Stainless Steel Overbraid and Green Acme wrench-less tank connectors. The added feature of the Stainless Steel Overbraid makes the 24" hoses very strong and almost squirrel-proof.

How does a Manual Tank Changeover Valve Assembly work?
The changeover valve will assemble into any low pressure propane regulator.  Using two propane tanks and one tank goes empty, just turn the yellow lever to the full tank. Close the tank valve and unscrew that Green Acme now you are free to remove the empty tank for replacement. A simple solution when running out of gas at the wrong time.

How does an Automatic Changeover Low Pressure Regulator work?

Having an Automatic Changeover Regulator is one of the best solutions to avoid running out of gas. The regulator automatically switches from the empty propane tank to the full reserve tank, ensuring a continuous gas flow. The color of the dial changes from a highly visible green to red signaling that the  first cylinder is exhausted while the valve automatically changes to the remaining full tank. Rotation of the handle to the full cylinder will restore the green color on the indicator.  The built in safety back check permits one to change out the empty tank while the full tank is operational.

Why order the COM-AC with Stainless Steel Overbraid TANK Hoses?

Stainless Steel Overbraid hoses makes the hose almost impenetrable to
squirrels and rodents. These animals are atrracted to the smell of propane
and natural gas. If you plan to hook up your COM-AC to your propane tank
on a semi-to-permanent basis and you live in an area well known to have
squirrels, you might want to consider the Stainless Steel Overbraid option.

GR9450 - Compact Twin Stage Low Pressure Regulator

  GR9450

GR9450 - Compact Twin Stage Low Pressure Regulator, set at 11" WC.
Gas Inlet is 1/4" Female NPT and the Gas Outlet is 1/2" Female NPT.
400,000 btu/hr Maximum Output. Dimensions: 7.5"L x 4.25"W x 3.25"H.

Includes mounting brackets and a 204051 Full Flow POL tank fitting.
(Unless you purchase it with a Red Acme or MANC tank connections).


The GR9450 is a combination of the First and Second stage regulators into a single unit. Starts with the First Stage which its preset at 10 PSI then it reduces down to the Second Stage which its preset at 11" WC but have an ajustment from 9" to 13" WC. The Gas Oulet is 1/2" Female NPT.

For a 1/2" ID Hose for the Outlet side of the regulator check out our
Natural Gas Hose webpage or the Replacement Hoses page.


In most cases other regulators will not maintain this basic operating
pressure in a very cold weather because the tank pressure been so low.
This unique model will maintain 8.5" WC even in the very cold environment.
Also
very useful for small domestic applications requiring higher gas
volumes than available from many normal low pressure preset regulators.


We offer free shipping to 48 U.S. States. Wt. 4#.

Why use a twin stage regulator?  

The Twin Stage Regulator starts with the First Stage which reduces the unregulated tank pressure down to a preset 10 PSI. Then the Second Stage regulator will maintain a constant 11" WC pressure. Having a Twin Stage regulator will reduce the possibility of freeze-ups, which often occurs more frequently as the btu/hr demand increases. Also these units are mostly used in RV's to provide enough pressure for all the appliances and its required by Federal code on all RV's to have a Twin Stage Regulator.

Why would someone want the First Stage and Second Stage Regulators pre-mounted and pre-plumbed on a panel?

First Stage and Second Stage Assembly which is already plumbed together may be very useful for situations where you intend to have a portable propane tank close to the house or very near a propane fueled generator. For use with stand-alone, higher Kilowatt emergency generators which rely on larger volumes of propane from portable tanks. Also this Assembly will be for convenient for systems that need a higher pressure Btu's then the common regulators, sense this combination puts out 950,000 Btu/hr.

GR918 - High Pressure Regulator, First Stage

  GR918

GR918 - High Pressure Regulator, First Stage set at 10 PSI.
Gas Inlet is a Female POL and the Gas Outlet is 1/2" Female NPT.

2,500,000 btu/hr Maximum Output. Dimensions: 8.75"L x 5.5"W x 4.75"H.

The Gas Inlet is a Female POL and the Gas Outlet is 1/2" Female NPT. It also includes a GR-905 universal mounting bracket and a 204051 Full Flow POL tank connector.

Why use a First Stage and Second Stage Regulator Separately?

When having a long distance from a large supply tank and the point of use of the gas, then installation of the First Stage Regulator (high pressure) separately from the Second Stage (low pressure) Regulator will avoid pressure drops in the gas delivery downstream.
