CALPOSE 2-Stage RV Propane Regulator with 18" Stainless-Braided Hoses, Dual-Tank Auto Changeover & Gauge

CALPOSE 2-stage regulator with an 18" stainless braided RV tailpipe hose and integrated gauge lets you run two propane cylinders safely and switch between them without interruption.

Built for RVs, travel trailers and campers that use dual refillable propane tanks, this unit combines a durable brass 2-stage regulator with two 18" pigtail hoses, pressure gauges and an easy-to-read color indicator. The rotary selector lets you choose which tank supplies gas while the visual fill indicator shifts color when a tank runs low. Every fitting and hose uses heavy-duty materials for long service life and secure connections.

How does the dual-tank changeover work?

The regulator automatically maintains consistent downstream pressure while allowing you to run two cylinders. Use the rotary pointer to select the active tank; when the selected tank is low the indicator changes color so you can swap cylinders before gas flow becomes interrupted.

• Two-stage regulation for stable outlet pressure under load
• Rotary selector to choose primary or reserve tank
• Color-changing fill indicator for quick visual checks
• Automatic uninterrupted changeover when tanks are installed correctly

What materials and connections are included for lasting performance?

This system is built mostly from solid brass and stainless-steel braid to resist corrosion, wear and vibration in mobile use. Inlets and outlets match common RV fittings so installation integrates with most camper plumbing without adapters.

• 100% solid brass regulator and fittings for durability
• Two 18" stainless steel braided QCC1 pigtails with gauges
• 1/4" SAE inverted flare inlets and 3/8" female NPT outlet compatibility
• Includes sealing tape and a wrench for installation

How much capacity and pressure can this regulator handle?

The unit is rated to support high demand appliances across both cylinders, with separate capacities for primary and reserve positions. It’s sized to manage common RV loads without frequent changeovers when tanks are filled appropriately.

• Primary cylinder capacity: 210,000 BTU/hr
• Reserve cylinder capacity: 130,000 BTU/hr
• Hoses fitted with QCC1 and 1/4" male inverted flare ends for standard tank hookups
