This 12-inch adapter hose is built for tanks and appliances that use ACME-nut cylinders and 1/4-inch inverted-flare inlets. A type-1 back-check valve is integrated into the body, stopping backflow when the line disconnects or pressure drops during travel. Flexible thermoplastic with thermal wrapping resists kinking and heat damage. Fully crimped brass ferrules ensure leak-free connections.
