Cone sealing performance: the pressure down to self-21Mpa 1.5mpa time less than 50s, otherwise there should be sealed grinding cone.

Tapered seal performance: Pressure from 21 to 1.5 MPa MPa a period of not less than 50s, otherwise it can be abrasive sealed taper.

Wedge-type seal performance: The pressure falls from 21MPa to the 1.5MPa time many in 50s, otherwise needs to grind the seal conical surface.

Conical sealing performance: 21MPa pressure not less than 50s to 1.5MPa time, you will need ground sealing cone.
