Fairview GR-630B RV Propane Regulator — 30 PSI High-Pressure, 500,000 BTU Capacity

Built for high-demand LP systems, the GR-630B combines robust capacity with a small footprint so you can upgrade or replace your regulator without reworking your gas lines. Its zinc-alloy housing resists corrosion while factory calibration maintains consistent pressure for heaters, grills, generators and other large appliances used on the road or off-grid.

How does the GR-630B perform with multiple appliances running?

This regulator is designed to handle heavy simultaneous loads. With a rated flow of 500,000 BTU per hour and a fixed 30 PSI outlet, it supports dual tank setups, kitchen ranges, space heaters, and generator connections without significant pressure drop.

• 500,000 BTU/hr capacity for sustained high demand
• Fixed 30 PSI output suited to appliances needing pounds-per-square-inch pressure
• Stable flow under continuous and intermittent loads

How easy is installation and replacement?

Installation is straightforward: the compact regulator measures just over 4" x 3" x 2.8" and uses common 1/4" FPT inlet and outlet threads. That makes it a quick swap for many camper and RV gas systems with minimal tools required.

• 1/4" female pipe threads on inlet and outlet for standard hookups
• Lightweight 7-ounce body fits tight compartments and tank mounts
• No re-plumbing needed for most regulator replacements

What materials and durability features protect the regulator outdoors?

The GR-630B uses a zinc-alloy housing and precision factory adjustment to resist corrosion and hold calibration through varied conditions. Its compact construction reduces exposure points and simplifies mounting in protected areas of the RV or trailer.

• Zinc-alloy case for corrosion resistance and long service life
• Factory-set output preserves consistent pressure without field tuning
• Compact shape limits snagging and fits common tank compartments

Will this regulator work with my existing RV propane plumbing?

If your system uses 1/4" FPT lines and requires a 30 PSI supply, the GR-630B will integrate directly. It’s intended for systems that demand higher pressure than typical low-pressure WC regulators, such as certain heaters or generators.

• Direct-thread compatibility with many RV regulator kits and hoses
• Best for setups specified to use pounds-per-square-inch regulation
• Not a replacement for low-pressure inch-of-water systems

Who this is for: The Fairview GR-630B suits RV owners, camper builders, and trailer technicians who need a compact but powerful regulator for high-demand LP appliances. Choose this unit if your setup requires a 30 PSI feed and a high BTU capacity for dual tanks, generators, or larger onboard appliances. It’s also a solid upgrade when you want a corrosion-resistant housing and a regulator that installs quickly without major plumbing changes.
