Thread Identification Kit


A kit of the highest quality, the BQ2100 has gauges for the vast majority of brake plumbing threads, both male and female. Gauges are color-coded for fast selection. The threads are hardened for long life, and each gauge is available separately as a replacement part.

The gauges can also be used to block off fluid ports during service.
