With the fittings, the older-style BSP stuff has 3 main pieces – the body, the Olive (inner and outer) and the cap. You can either buy the olives (https://cutpriceracing.com.au/store/Olive-Outer-for-Brake-Line/ and https://cutpriceracing.com.au/store/Olive-Inner-for-Brake-Line/ the inner is pushed into the middle of the line, the outer is slid over the line and the two compress together when fitted) and re-use your Connector, or we recommend getting one of the new speedy fittings which don’t require the olives (much easier to use and you don’t waste the olive each time you re-fit the line) which can be found here:
