It is used to join two sections of flared tubing in heavy-duty truck air brake, fuel, or hydraulic systems. The 45° flare creates a reliable metal-to-metal seal without the need for sealing compounds. Replace this fitting when it is damaged, corroded, or when re-plumbing a system to maintain leak-free connections.
