I could do with some replacement O rings, the tiny ones on the bleed kit fitting. I have no idea of the spec/ dimensions, possibly 6.5mm external diam, 4.0mm internal and a thickness of 0.7mm. Any ideas where to source the correct ones?
Also- the tubing is now pretty opaque and very stiff. Again- ideas for replacement?
Or just buy an Ebay bleed kit and be done?
