Each product is packaged independently (product-bubble bag-inner box-outer box).
All packaging is designed for international shipping protection. Inner packaging includes individual protection for each cylinder to prevent damage during transit.
Q9:| What surface treatment do you use on your aluminum cylinders?
A9:Our standard aluminum brake/clutch cylinders undergo sandblasting + natural (clear) anodizing on the exterior for an OEM-like finish. The piston and bore surfaces receive Type III hard anodizing (25-50μm, HV350+) for exceptional wear resistance - this is the industry standard for long service life.
Q10:| How can I tell if the surface treatment is good quality?
A10:For aluminum pistons: the darker and more matte the black finish, the thicker and harder the anodizing layer - a quality piston should appear deep black with zero gloss and resist fingernail scratching. For iron cylinders: E-coat should be uniformly black and semi-glossy across all surfaces including threads; any rust spots or uneven coating indicate poor pretreatment. For Dacromet: should be uniformly silver-grey matte with no bare metal spots or drips.
