Furnace Gas Valve Cross-Reference Chart

Every cross below comes from the manufacturers’ own published interchange guides — Resideo’s 2023 Application Selection and Cross-Reference Guide, White-Rodgers bulletin R-4360, and Robertshaw 150-2320C. 373 Honeywell/Resideo VR8-series numbers, 947 V800 standing-pilot numbers and 488 VS8000 millivolt numbers, each showing the Robertshaw and White-Rodgers equivalents side by side.

Bushings: the size trap, and who ships them

Here is the thing that catches people, and it is worth understanding before you look at a single part number.

Almost none of the cross-references on this page are the same physical size as the valve you are holding. Take Honeywell VR8200A2132, one of the most-searched valve numbers there is. It is a 1/2" × 1/2" body. Its published equivalents are not:

There is no true drop-in dimensional equivalent from any competitor. Every one of them is a bushed fit. That is normal and it is not a problem — but only if the bushings are in your hand when you get to the furnace.

So when a table below shows a cross that is a different pipe size, read it this way: on a universal, shrug — the adapter is in the box. On an OEM part number, add bushings to the ticket.

One more sizing note that is easy to miss: pipe size is the flexible constraint here. Capacity, voltage, ignition type and gas type are not. Those are covered next.

What the different gas valves look like

Gas valves are grouped by what they do, not by who made them. These are photographs of stock on our own shelf — tap any of them for the full specification.

Standing pilotVR8200A2132A pilot stays lit and the valve simply opens to the burner. Note this one is 1/2 x 1/2 — every published cross for it is physically bigger, so a replacement is a bushed fit.Millivolt36C03-433Runs off a thermopile with no transformer anywhere. Never cross a millivolt valve to a 24 volt one; they only look similar.Two-stage universalVR8345Q4563Universals ship with reducer bushings and a conversion kit, which is why pipe size is the flexible dimension and ignition type is not.White-Rodgers two-stage36J54-214Same job, different maker. What has to match is ignition type, coil voltage, gas type, stage count and capacity — not the brand.Aftermarket direct624775RBuilt to replace one OEM number without adapting anything. When one exists it is the simplest path.

The six things that must match

White-Rodgers publishes a five-question selection guide and Robertshaw a ten-point checklist. Boiled down, these are the things that will bite you:

Pipe size is the one that flexes, because of the bushings. Everything above does not.

Regulator setting is also adjustable rather than fixed: Honeywell ships factory-set at 3.5" WC, White-Rodgers 36J single-stage adjusts 2.5–5.0" WC on natural and 7.0–12.0" on LP. A valve is suitable if your appliance nameplate figure falls inside its adjustment range — and you set it with a manometer, not by eye.

Prove it is the valve first

The gas valve sits downstream of every safety in the chain, which is exactly why it takes the blame for faults that are not its own. Before you buy one:

The three misdiagnoses we see most

• A flame-proving problem. A dirty flame sensor, weak flame signal or bad ground makes the board shut the valve within seconds of light-off. The valve gets replaced; it was obeying the board correctly the whole time. Check the ignitor and flame sensor first.
• A pressure switch that never made. A cracked or blocked hose, or a plugged inducer port, and the sequence never reaches the valve at all.
• “It is leaking through.” This one is worth understanding: every gas valve leaks a little — manufacturers publish allowable leakage rates. Residual gas dissipating out of the manifold is normal, and an electronic leak detector is sensitive enough to flag it. The real question is whether leakage exceeds the manufacturer’s threshold, which is a timed bubble test against a published chart, not a sniffer reading. A lot of good valves get replaced on a sniffer alone.

If you have worked through all of that, the replacement procedure is on our gas valve replacement guide.

Which universal covers what

These are the current Resideo universals from the 2023 guide, with what each one actually covers. Note the older sheets still circulating list valves that have since been superseded — VR8345H4555 became VR8345K4809, and VR8300A4508 became VR8300M4406.

White-Rodgers and Robertshaw universals

White-Rodgers consolidated onto three families. 36H is the high-capacity universal (50–400 kBTU/hr, HSI/DSI/proven pilot, single and two stage), 36J is the compact non-piloted intermittent-ignition line (40–210 kBTU/hr), and 36C covers standing pilot including millivolt. The heavy hitters by coverage:

All 36H models ship with the nat/LP conversion kit and the reducer bushing kit included. Robertshaw’s equivalent concept is the Uni-Kit — the 720-series arrives factory set at 3.5" WC natural with the LP conversion kit in the box.

Honeywell / Resideo VR8-series cross-reference 373 part numbers

The 24-volt electronic-ignition family — VR8200 standing pilot, VR8204/VR8304 intermittent pilot, VR8205/VR8215/VR8305 direct and hot-surface ignition, VR8245/VR8345 universals. This is what is on most gas furnaces built in the last forty years.
