Compatibility & Fitment

• Supply Tanks:Fits 20lb, 30lb, and 40lb cylinders (LP gas tanks used for BBQ grills and RVs).
• Disposable Cylinders:Fits all standard 1lb / 16.4oz throwaway bottles (e.g., Coleman, Bernzomatic, Worthington).
• Applications:Ideal for refilling small tanks for camping stoves, portable heaters (like Mr. Heater Buddy), lanterns, and small tabletop grills.

When to Use This Adapter

• Cost Savings:Refilling 1lb bottles from a 20lb tank is significantly cheaper than purchasing new disposable cylinders.
• Waste Reduction:Allows for the reuse of disposable cylinders, keeping empty metal bottles out of landfills.
• Emergency Preparedness:Ensures you can provide fuel for small emergency heaters or stoves using your larger home BBQ tank.
• Incomplete Fills:The integrated valve helps manage the "vapor lock" issue often encountered during refills, allowing you to bleed air or stop flow instantly.

Refilling Safety & Tips

• Outdoor Use Only:Never refill propane tanks indoors or in a garage. Propane is heavier than air and can pool in low spots, creating an explosion hazard.
• The "Freezer Trick":For a more complete fill, place the empty 1lb cylinder in the freezer for 30 minutes and keep the 20lb tank at room temperature. The pressure differential helps pull liquid propane into the small tank.
• Tank Inversion:To transfer liquid (rather than just gas), you must turn the 20lb tank upside down during the refill process.
• Weight Limit:Never overfill a 1lb tank. Use a digital scale to ensure the total weight does not exceed the manufacturer's "Full" specification (usually around 2lb total weight including the bottle).
• Leak Check:After refilling, apply soapy water to the 1lb tank valve to ensure it has sealed correctly. If bubbles appear, the internal seal may be faulty; do not store the tank indoors.
