Buying Guide
What to consider when choosing an RV propane regulator kit
- Tank compatibility: Ensure the regulator supports dual-tank operation and matches your current tank fittings.
- Changeover reliability: Look for automatic changeover with a clearly visible indicator so you know when to refill.
- BTU rating: Check the primary and reserve BTU/hr ratings to ensure adequate gas flow for your appliances.
- Fittings and hose length: Confirm inlet/outlet fittings (1/4″ SAE inverted flare and 3/8″ NPT) and select hose lengths that suit your RV layout.
- Materials and durability: Stainless braided hoses and brass components provide corrosion resistance and longevity outdoors.
- Certification and safety: CSA or UL listings can add confidence in performance and safety.
Installation tips and safety reminders
- Follow manufacturer guidelines for tightening connections to avoid leaks.
- Avoid installing in areas with high vibration or heat exposure that could loosen fittings.
- Test for leaks using approved procedures before first use and periodically thereafter.
Choosing based on RV type
- Compact RVs or vans: A compact two-tank regulator with shorter hoses may reduce clutter and simplify routing.
- Full-size campers or trailers: Longer hoses and heavy-duty braided options can accommodate larger layouts and prevent strain on connections during travel.
- Occasional campers: A straightforward regulator with a visible indicator helps ensure refuel timing without interrupting supply.
Maintenance considerations
- Inspect hoses for cracks or wear, especially where hoses bend around cabinetry or chassis.
- Replace regulators and hoses that show signs of corrosion, cracking, or leakage.
- Store spare parts and tools for quick field adjustments during trips.
