General guidance

Component knowledge

Understanding this component

In general, a connector is a fitting that joins two lines, hoses, or components so fluid or air can pass between them, or that links electrical wiring. In heavy equipment, connectors help make service and assembly work easier by allowing parts to be installed and separated as needed.

What to check before ordering

Use part number 0017025 when ordering this connector. Because catalog records associate it with lines assemblies, check the recorded parent conditions and your machine's configuration before ordering to confirm it matches your application.
