1150 brake question

[Gordon]

Hi
My Dad and brother based in Pretoria are having a bit of a problem bleeding an ABS 1150 gs
Can any one identify the part in the photoes

1) Is it a speed bleeder ?

2) Aftermarket or original ?

3) why would you fit it if its aftermarket ?

4) can it be removed and a normal bleed nipple be fitted ?

Thanks Gordon
