It connects two male-threaded pipes or fittings, commonly used in low-pressure air, fuel, and hydraulic systems. On heavy-duty trucks, it's often found in airline repairs, fuel line connections, and general plumbing. You would replace it when the coupling becomes corroded, cracked, or starts leaking.
