BRAKEQUIP FITTING - FEMALE M10 X 1 DPS (SPLINE)

DPS refers to the spline configuration on the fitting, which works with the M10 x 1 thread pitch. The spline profile is part of how the fitting seats and locks into compatible brake line connections. Brakequip uses this designation consistently across their brake fitting line, so if you already have a DPS-compatible port or adapter, this female fitting should match up to it correctly.
