In general, a union-flared fitting is a connector that joins a flared tube or line to another component in a fluid system, so the two sides can be coupled and uncoupled for service. Flared connections are common in fuel, lubrication and hydraulic circuits on heavy equipment because they seal against a machined cone rather than relying on threads alone.
Use part number 0307982 as the catalog reference when requesting this item. Before ordering, confirm the recorded catalog conditions for your engine or machine and verify the fitting's size and connection type against the component you are replacing.
