-3 size is the most common size for brake lines and oil pressure gauge lines. It is also popular for clutch lines.
-4 size is ideal for clutch lines. It is also used for brake lines where a lot of fluid is displaced (such as drum brake systems).
(Note: Only steel, stainless steel, or high pressure brass fittings should be used with brake lines. We recommend against aluminum fittings in brake systems.)
Note: You must strip the black outer covering back prior to installing your hose ends. The hose end collar must bear against the braid, not against the black covering.
