Emerson-Fisher LP-Gas Equipment R232A-BBF Propane Two-Stage Regulator, 10.2"–13" WC, 550,000 BTU

The Emerson-Fisher R232A-BBF is a compact, two-stage propane regulator that delivers steady outlet pressure (10.2"–13" water column) for residential, RV, and small domestic LP-gas systems.

When consistent propane pressure matters for appliances, heaters, or generators, the R232A-BBF provides a durable, high-capacity solution in a small package. Designed for installations that need reliable two-stage regulation without a large footprint, this unit supports up to 550,000 BTU and fits into tight tank compartments found on homes, campers, and backup power setups.

How does this regulator keep flames steady during changing tank conditions?

The R232A-BBF uses an integral two-stage reduction that smooths pressure changes from the tank to the outlet, preventing sudden surges or dips in gas flow. Two-stage control reduces the workload on downstream appliances and helps maintain consistent burner performance across normal operating variations.

• Integral two-stage design for stable outlet pressure
• Maintains 10.2"–13" WC outlet for predictable appliance operation
• Screened vents and code-oriented vent placement for reliable function

What installations and equipment can this regulator support?

This regulator is sized for residential and small domestic LP systems, RVs, trailers, and generator connections where a compact regulator is required. With a 550,000 BTU capacity and 250 psig max inlet rating, it supports whole-house appliances, furnaces, grills, and other high-demand loads when installed according to local codes.

• Rated for up to 550,000 BTU per hour capacity
• 250 psig maximum inlet pressure for common supply conditions
• Compatible with 100 lb cylinder systems and typical residential propane setups

How does the R232A-BBF simplify replacement and tight installations?

The regulator's compact 7" x 5" x 5" body slips into cramped enclosures where larger regulators won't fit, making it a good choice for retrofits and replacements. Standard FNPT ports match common line fittings to streamline installation and reduce the need for specialty adapters.

• Small footprint fits tight tank compartments and enclosures
• 1/4" FNPT inlet and 1/2" FNPT outlet for common hose and line connections
• Durable metal construction suited for professional replacement jobs

What safety and code-aware features are included?

The unit incorporates vent placements and screened vent openings intended to meet NFPA 54/58 guidance when installed correctly. A downward-facing first-stage vent and a second-stage vent positioned over the outlet limit contamination and water ingress while routing vented gases safely away from components.

• 7/16-24 inverted flare screened drip-lip first-stage vent (faces downward)
• 3/8 NPT screened second-stage vent positioned over outlet
• UL-listed two-stage pressure control for recognized safety performance

Who this product is for: the Emerson-Fisher R232A-BBF is intended for homeowners, RV owners, contractors, and installers who need a compact, high-capacity propane regulator that maintains steady outlet pressure for multiple appliances. Choose this unit when space is limited, you require two-stage pressure stability, and you want a regulator compatible with common tank and line configurations for residential or small domestic LP systems.
