Description
The BrakeQuip BQ9188 is a male M10 x 1.5mm brake line fitting for 3/16 in. OD tubing. It shares the M10 major diameter with the BQ9175/BQ4511 family but uses a coarser 1.5mm thread pitch rather than 1mm — the two are easy to mix up by sight but will not thread together. Match the pitch stamped on your caliper, hose end, or original fitting before ordering.
