The Kovea Brass LPG Adapter has a Coleman propane input and a Lindal Valve Output, enabling a Lindal Valve stove to run on commonly available Coleman 1lb. Propane Canisters. The Brass LPG Adapter simply threads onto the Coleman Canister and your stove's input end threads onto the Brass Adpater. The Brass Valve rests in closed position so gas does not spew out if the stove is unthreaded from the Adapter. A regulator on the side is adjustable for different stoves or altitudes.
