HB 2.8mm I.D.

1 set contains 2 equal pistons 

The outer shape has been specially designed to cause less friction and limited wear.

The material has a very low coefficient of friction, is much more resistant to wear and has much better dimensional stability in contact with fluids and oils.
In other words, the diameter of the pistons and holes remain the same under all conditions.
In addtion, the material is very strong, so it will not break after high impact jumps.

The finishing is done entirely on a CNC controlled machine. Both turning and drilling. This according to very precise tolerances. And all pistons are laser marked so you can easily select the right piston at any time.
