got 3/8 brake tube and need a weld-on end with 5/8-18 threads. is this the right one?

Answer by: Customer Support on Sep 30, 2025, 11:33 AM

For a welded tube connection, this fitting matches a 3/8 inch tube size and uses a 5/8-18NF thread, so it fits the common setup where you weld the fitting onto 3/8 brake tubing and end up with a threaded tube end.
