Fluid attack:
A diameter and hardness control is carried out on the band, placed on the piston. Once the PTFE process has been carried out and before 24 hours have elapsed, it is immersed in the fluid for 72 hours at 80 ℃
Acceptance Conditions:
There can be no breakage or detachment of material. The variation of hardness ≤6%, the diameter variation ≤0.20%
Specifications:
100% tested by Go no-Go gauge
Coaxiality can be control within 0.05mm
4 round and square holes
