Question by: Rhonda B on Jun 9, 2025, 9:40 PM

What size brake line does this bulkhead nut fit? Just wanna make sure it's the right one before I order it.

Answer by: Customer Support on Jun 11, 2025, 6:19 AM

This bulkhead nut is made for a 5/8-inch brake line with 18NF (National Fine) threads. That fine thread is good for keeping everything tight, especially where there's vibration.
