Brake and clutch hard line fitting
This fitting is vital for a good seal at your master cylinder, for both clutch and brake hard lines. It's the same fitting used in the 7/8" slave cylinder. If you have the 1" slave cylinder, you will need the rubber line to attach to the slave cylinder due to the larger fitting on the rubber line. If you plan on flaring any lines, these nipples are crucial!
Lots of people over tighten and crack these, so they no longer seal. So this is a great spare to have for any Spridget! Get a few!
