A billet separator with a 9.5 mm bore, listed for AN3 hose. AN3 is the size most often used for brake and clutch lines and for pressure gauge feeds, all of which tend to be run in pairs and all of which benefit from being held rigidly rather than left to flap. Braided brake line rubbing on a suspension arm or subframe is a genuine safety concern, not just an untidy one, so a separator plus a mounting point is cheap insurance. The two halves clamp over the lines and can be anchored to the chassis or left as a floating spacer mid-run. Confirm your hose outside diameter matches the 9.5 mm bore before ordering.
