Gas One Propane Refill Adapter with 4-Ft Hose (1 lb to 20 lb)
A solid brass refill adapter paired with a 4-foot hose so you can top up 1-lb propane canisters from a standard 20-lb BBQ tank. The QCC1/Type 1 fitting threads onto the big tank by hand, and the CGA600 end mates with the small cylinder valve. On a warm afternoon a 1-lb bottle fills in under two minutes once you learn the tilt-and-vent rhythm. Threads are cut precisely, which is the part cheap adapters get wrong — a sloppy thread here means a leaking seal at 100+ PSI.

You have done the math and it stings: five or six single-use green bottles per trip at $6-$8 each adds up to more than the food you cooked on them. Your 20-lb BBQ tank at home is three-quarters full, and you are at the store buying more disposables anyway — because nobody ever told you a $15 brass adapter turns the big tank into a refill station.
🏆 How It Compares
The cheapest way into refilling your own bottles — but it is a tool, not a legal fix, and it works best on a warm day with a scale.
Pros & Cons
✅ Pros
- Solid brass body with precise QCC1/Type 1 threads — seals without PTFE tape
- Includes a 4-ft hose so the small canister can sit on a scale while filling
- Hand-tighten only — no wrenches needed at camp
- Fits the standard 20-lb BBQ tank most families already own
❌ Cons
- Only works when the donor 20-lb tank is warmer than the small cylinder — cold tanks need a warm day or a water bath
- You must weigh the bottle or watch the vent closely; overfilling is easy if you rush
- Not for use with disposable-only canisters that are already past their service date
