Browse Caterpillar modelsGeneral guidance
In general, a flared reducer is a fitting used in tubing or line systems to change from one line size to another, typically with a flared end that seals against a mating flared connection. In heavy equipment and engine cooling circuits, such fittings help connect lines of different diameters while keeping fluid paths secure.
Order part number 0308145 exactly as listed. The catalog associates it with specific cooling system line assemblies, but those associations are catalog occurrences, not confirmed fitment for every machine. Check the recorded serial number and configuration conditions against your engine before ordering.
