GASPRO Solid Brass 20 lb to 1 lb Propane Tank Adapter
A one-piece solid brass converter that bridges a full-size 20-lb tank's QCC1/Type 1 valve to a 1-lb appliance connection. Screw it on and the bottle-top stove or lantern that normally eats green canisters now runs off the big tank — no adapter, no small bottle, no refilling at all. At under $10 with more than 3,400 ratings, it is the cheapest way to stop buying disposables: not by filling them, but by removing them from the setup entirely.

Basecamp, day three, and the bottle-top stove is on its second green canister while a nearly full 20-lb tank sits ten feet away doing nothing. The obvious move — run the small stove off the big tank — is a ten-dollar brass fitting away, and it removes the whole disposable-bottle chore from your trip.
🏆 How It Compares
Not a refill tool — a refill replacement: run the appliance off the big tank and skip small bottles entirely.
Pros & Cons
✅ Pros
- Solid brass construction with correctly cut threads — no leaks at the joint
- Runs a 1-lb appliance straight off a 20-lb tank, eliminating canisters entirely
- Under $10 — cheaper than two disposable bottles
- Fits the standard QCC1/Type 1 valve on nearly every household BBQ tank
❌ Cons
- No hose included — the appliance mounts directly on the tank and can feel top-heavy with a big pot
- Only converts the connection; it does not let you refill small canisters
- Direct-mount setups put the burner close to the tank, so keep the flame clear of the brass
