You are here: Home > LP Gas > LP Regulators

LP regulators reduce the high pressure in your propane tank (up to 200+ PSI) down to the low pressure your RV appliances need (typically 11 inches water column, about 0.4 PSI). A failed or improperly sized regulator can cause appliances to underperform, produce yellow flames, or create dangerous overpressure conditions.

Regulator types

  • Single-stage regulators: One pressure reduction step. Simple and common on small systems.
  • Two-stage regulators: Reduce pressure in two steps for more consistent output, especially in cold weather.
  • Automatic changeover regulators: Connect two tanks and automatically switch to the reserve when the primary empties. An indicator shows which tank is in use.
  • High-pressure regulators: For appliances that need higher pressure than standard (some grills and heaters).

Key specifications

  • BTU capacity: Regulator must supply enough BTUs to run all your appliances at once. Add up furnace, water heater, stove, and fridge BTU ratings.
  • Inlet connection: POL (older style) or ACME/QCC1 (newer style with hand-tightening).
  • Outlet connection: Usually 3/8-inch flare for RV pigtails.

Regulators should be replaced every 10-15 years or immediately if you notice pressure problems or physical damage. Contact us if you need help sizing a replacement.

Free shipping on most orders $99+ (US lower 48). Expert support and 90-day returns.
