Application:oil pressure disc brake
Model:M315/M355/M395/396/M446
M505/M525/M775/MT200 etc.
Weight:about 1g/pair
Material: Copper
Precision machining of copper materials, copper compared to other metals have better compressive strength, durability, and ductility, the tightness of the ring needs to be made of this material.
The tight squeeze deformation has a very good sealing and copper is not picky about the type of brake fluid, no matter what kind of brake fluid do not need to worry about it aging and oil leaks
