<h3>About Suburban Manufacturing</h3><p><strong>Suburban Manufacturing</strong> has been a cornerstone of the RV industry for over 75 years. <a href="/7593-suburban-mfg">Suburban Mfg</a> traces its roots back to 1947, when it began as the Hunt Heater Company, producing small gas space heaters in Dayton, Tennessee. A pivotal moment came when a customer asked whether one of Suburban's greenhouse heaters could be adapted to run on 12V for use in a motorhome — and the RV-focused legacy of the brand was born. Today, Suburban is headquartered in the same Dayton, Tennessee community it has called home for decades, operating out of a facility that spans more than 300,000 square feet.</p><p>In 1998, Suburban joined the <strong>Airxcel</strong> family of brands, which has grown into the leading designer, manufacturer, and distributor of critically functional products for the RV industry. That partnership gave Suburban the resources to continuously refine and expand its product line while maintaining the hands-on manufacturing quality that built its reputation. Suburban's engineers have pioneered a long list of RV industry firsts — from space-saving, horizontally vented gas heating systems and solid-state spark ignition technology to efficient DC furnace motors and glass-top ranges that double as counter space when not in use.</p><h3>What Suburban Makes</h3><p>Suburban's core product lineup covers the essential comfort systems that RV travelers depend on every day. The brand is perhaps best known for its <a href="/7593-suburban-mfg-heating-200526">RV heating solutions</a>, including a comprehensive range of ducted furnaces and wall heaters engineered specifically for the space constraints and power demands of motorhomes and travel trailers. Suburban furnaces are designed to deliver reliable warmth using propane, with efficient DC blower motors that minimize battery draw — a critical factor for off-grid campers.</p><p>Beyond heating, Suburban has long been a trusted name in RV kitchen appliances. Their <a href="/7593-suburban-mfg-stoves-cooktops-201021">stoves and cooktops</a> are built with the unique requirements of RV galleys in mind: compact dimensions, durable construction, and propane-compatible burners that perform reliably on the road. Suburban has also expanded into <a href="/7593-suburban-mfg-stoves-cooktops-202596">outdoor cooking</a>, offering cooktops and cooking appliances designed for the camp kitchen experience outside the coach — including griddles and other galley accessories inspired by contemporary European design and manufactured in America.</p><p>Most of Suburban's product line is backed by a <strong>2-year limited warranty</strong>, reflecting the brand's confidence in its own manufacturing standards. Each product goes through a rigorous series of quality and safety tests before leaving the Dayton facility — a commitment that has made Suburban a preferred OEM supplier for many of the largest RV manufacturers in North America.</p><h3>A Legacy of Innovation</h3><p>Suburban's influence on modern RV design is difficult to overstate. The company helped pioneer the glass-top range, which transformed compact galley kitchens by providing valuable counter space when burners aren't in use. More recently, Suburban has pushed into all-in-one solutions: their <em>RV One</em> system combines an on-demand water heater and NT furnace into a single unit engineered for the growing segment of compact and lightweight travel trailers. With a track record of listening closely to the needs of RV builders and end users alike, Suburban continues to set the standard for what RV appliances can be.</p>

Product Details

Suburban Mfg 523003 is a combination two-stage propane regulator designed to control the flow of LP gas to all appliances in your RV or motorhome. The two-stage design first reduces cylinder pressure down to 10 psi, then a second stage maintains a stable, consistent working pressure of 11 inches water column at the appliance — ensuring reliable performance regardless of tank fill level or ambient temperature.

Key Features:

  • Combination two-stage regulator — first stage reduces cylinder outlet pressure to 10 psi
  • Second stage maintains stable working pressure of 11" water column
  • Inlet: 1/4" female pipe thread (FPT)
  • Outlet: 3/8" female pipe thread (FPT)
  • Vertical vent orientation
  • Rated at 160,000 BTU/hour
  • Includes plastic vent covers required by RVIA standards
  • UL Listed for safety and compliance
  • Overpressure Protection Device (OPD) shuts off gas flow in the event of regulator malfunction
  • Limits environmental propane release to less than 2 psi — well below UL standard 144 requirements

The Suburban 523003 LP gas regulator is an ideal direct replacement for worn or aging RV propane regulators. The kit includes all necessary vent covers for RVIA-compliant installation, making this a complete, ready-to-install solution for your RV propane system.
