onlyfire Horizontal Two Stage RV Propane Regulator — Brass, 11"WC Outlet, 160,000 BTU Capacity

The onlyfire Horizontal Two Stage RV Propane Regulator is a durable brass regulator that delivers steady 11"WC outlet pressure and up to 160,000 BTU/hr for horizontal RV appliances.

This compact, horizontal-style regulator is designed for RV systems and other on-board propane applications where consistent pressure and reliable flow are essential. Built with integrated two-stage regulation and solid brass construction, it helps maintain safer, smoother delivery of propane to appliances such as stoves, heaters, hot water systems and generators.

How does this regulator maintain consistent propane flow?

The regulator uses an internal two-stage design to reduce tank pressure in two steps, which smooths out pulses and prevents pressure spikes at the appliance. That results in steadier flame performance and more reliable operation across multiple devices drawing gas at once.

• Integral first and second stages for staged pressure reduction
• 11"WC outlet pressure tuned for RV appliances
• Reduces cycling and pressure fluctuation under varying loads

What connections and capacities should I expect?

Onlyfire's horizontal regulator provides a 1/4" female NPT inlet and a 3/8" female NPT outlet, making it compatible with common RV plumbing fittings. It is rated to supply up to 160,000 BTU per hour at an output pressure of 11 inches water column, suitable for multi-appliance setups.

• Inlet: 1/4" female NPT
• Outlet: 3/8" female NPT
• Maximum capacity: 160,000 BTU/hr
• Outlet pressure: 11"WC (inches water column)

Is the construction suitable for RV and outdoor use?

The regulator is machined from 100% solid brass for corrosion resistance, tight sealing, and long service life in mobile and outdoor environments. The horizontal orientation is optimized for installations where the regulator mounts parallel to the appliance line or within tight RV compartments.

• Solid brass body for durability and leak resistance
• Engineered for horizontal mounting applications
• Designed to withstand vibrations common in vehicle installations

Which appliances can this regulator serve in an RV setup?

With its high BTU capacity and steady 11"WC outlet, the regulator is suitable for most RV gas appliances, including ranges, furnaces, water heaters, fireplaces and portable generators. It supports simultaneous operation of multiple devices when correctly sized and installed.

• Gas stoves and ranges
• RV furnaces and propane heaters
• Hot water heaters and propane fireplaces
• Gas generators and other onboard appliances

Who is this for? This onlyfire horizontal two-stage regulator is intended for RV owners, mobile-home technicians, and installers who need a rugged, high-capacity regulator that keeps propane pressure stable across multiple appliances. It's suited to retrofit or new installations where a horizontal regulator orientation and brass construction are preferred. Always follow local codes and manufacturer guidance when installing or replacing gas regulators.
