TurboBrake BH59 Hose with Factory Fitted TEKTRO barb/olive/nut/boot (hydraulic brake line)

• TurboBrake BH59 Hose with Factory Fitted TEKTRO barb/olive/nut/boot is a hydraulic brake line with factory fitted connectors, pre-assembled ready to install.
• BH59 is the most common type of hydraulic line used on eScooters.
• Factory fitted with TEKTRO style connector which has an o-ring (7mm OD x 1.5mm cross section). This connection is backward compatible with callipers and levers designed for the more traditional BH59 termination. The TEKTRO forms a better connection than typical BH59 barbs. Olive, compression nut (M8 0.75mm pitch thread) and boot/cover are also factory fitted.
• Presently available in a single length designed for handlebar extensions:
  • 150mm (total length with fittings 160mm).

Notes:

1. Refer to the TurboBrake Reference page for further information about hose and insert types such as Shimano BH59, BH90 and TEKTRO.
2. eSN also provides FlexIHose fitted hydraulic line which are fabricated with a braided steel mesh, making them more flexible with a slightly larger outer diameter of 5.5mm. Image below shows BH59 hose on left (TEKTRO o-ring barb and 3 pieces non-assembled) and the FlexIHose with the crimped connector on right.
   
   
3. Video showing TurboBrake HB427-4S 4-Piston Brake Calliper fitted via an extender (approx 80mm) and coupler. A good option as replacement for troublesome banjo bolt.
   
4. Use the eSN coupler if needing to join two hoses together.
5. The hose is not capped (sealed) and therefore, unlike the hoses provided 4S and 4H callipers (and most others) are not pre-filled with fluid.
