CALPOSE 2-Stage RV Regulator with 18" Stainless-Braided Hoses & Gauges — Brass Manual Changeover

CALPOSE 2-stage regulator with dual 18" stainless-braided pigtail hoses is a heavy-duty RV propane changeover system that lets you run two refillable tanks, choose the active cylinder, and monitor pressure with color-changing indicators and gauges.

Whether you tow a travel trailer, live in an RV, or outfit a camper, a reliable propane regulator and pigtail hose set ensures steady fuel delivery for cooking, heating, and appliances. This kit pairs a mechanical 2-stage changeover regulator built from solid brass with two 18" stainless-braided RV tailpipe hoses that include gauges and QCC1 fittings. Safety-oriented features, clear capacity specs, and a compact installation footprint make it a practical upgrade from older automatic regulators.

How does the two-stage changeover work and why does that matter?

The regulator lets you connect two refillable propane cylinders and manually select which tank supplies gas using the rotary selector. When the active tank drops low, the visible color-change indicator switches from green to red so you know to refill or switch tanks. The two-stage design also stabilizes delivery pressure to appliances for consistent performance.

• Rotary selector to pick primary or reserve tank
• Color-change indicator shows fill status (green to red)
• Two-stage regulation for steady outlet pressure
• Capacities: 210,000 BTU/hr primary, 130,000 BTU/hr reserve

What materials and connections are included for durability and leak resistance?

All major components are made from solid brass for corrosion resistance and long service life. The 18" hoses are stainless steel braided to improve flexibility and airtightness while protecting the inner hose from abrasion. Thread types match typical RV fittings so the kit connects to standard propane plumbing without adapters.

• Regulator and fittings: 100% solid brass construction
• Hoses: stainless steel braided RV pigtails for durability
• Inlets: 1/4" SAE inverted flare; outlet: 3/8" female NPT
• Hose fittings: 1/4" male inverted flare and QCC1 connector

Will this fit my RV and how do installation and replacement work?

The regulator is designed to work with dual refillable propane tanks commonly used on RVs, campers, and travel trailers. It connects to tank sizes between 5 and 40 lb and replaces most automatic changeover regulators while preserving continuous gas flow to onboard systems. The package includes sealing tape and a wrench to simplify hookup, and CALPOSE provides customer support if you need help during installation.

• Compatibility: dual 5–40 lb refillable propane/LP tanks
• Replaces existing automatic changeover regulators
• Includes sealing tape and wrench for installation
• Customer support and 2-year satisfaction guarantee included

How do the gauges and specifications affect everyday use?

Built-in gauges on the pigtail hoses let you check tank pressure at a glance so you can manage fuel before running out. The specified BTU capacities give a practical measure of how much load the primary and reserve tanks can supply, helping you plan longer trips or high-demand appliance use. Clear thread types and outlet sizing make it straightforward to match the regulator to your RV plumbing.

• Gauge-equipped hoses for quick pressure checks
• Primary capacity 210,000 BTU/hr; reserve 130,000 BTU/hr
• Outlet: 3/8" female NPT for standard connections
• Inlets: 1/4" SAE inverted flare for tank hookups

Who is this for: RV owners, full-time campers, and travel trailer users who need a rugged, serviceable changeover regulator with visible tank status and strong fittings. It suits anyone replacing an aging automatic regulator or upgrading to a more durable brass-and-stainless assembly for reliable propane delivery on the road. The included tools, tape, gauges, and a two-year guarantee make it a plug-and-play choice for DIY installers and techs alike.
