Description
Female tube joiner, M10 x 1mm thread. Joins two sections of brake tube flared to M10 x 1, or connects a line to any male fitting on that thread, so a run can be extended or a repair spliced in without a full line replacement.
M10 comes in three pitches you’ll meet on brake systems, 1, 1.25 and 1.5, and they are not interchangeable. The diameter alone won’t tell you which one you have. Measure the pitch before ordering, or bring the old fitting to compare against.
