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.
