In general, a flared connector is a fitting that joins tubing or hose lines using a flared end that seals against a matching fitting or nut. Such connectors are used in fluid lines on heavy equipment engines, where a secure, leak-resistant joint is needed between line sections. The exact construction and any supplied pieces are not stated in the catalog data for this part.
Use part number 0308310 as the reference when ordering this connector. Before purchasing, confirm that the catalog occurrences and any recorded conditions match your machine's engine serial number and line configuration, because a catalog listing does not establish compatibility for every configuration.
