main feature:

Meet API682 standard, the seal end face has high flatness and surface roughness, extremely low leakage;

Two-stage seals are formed in series. After the first-stage seal fails, the second-stage seal acts as the main seal to prevent a large amount of process medium from leaking. Different series of structural seals and material combinations can be selected according to specific working conditions;

The seal adopts cartridge type, which is convenient for installation and removal.
