Installation• Center the gasket on the f lange. This is ex-

tremely vital where raised faces are involved.Note: StandardANSI ring gaskets, when properlycut, should center themselveswhen the bolts are inplace.

• Useatorquewrenchandwell-lubricatedfastenerswithhardenedflatwasherstoensurecorrectinitialloading.

• Tightenboltstocompressgasketuniformly.Thismeansgoing from side to side around the joint in a star-likecrossingpattern.Seediagramsatright.

• All bolts should be tightened in one-third increments,accordingtoproperboltingpatterns.

• Retorque12to24hoursafterstart-up,wheneverpossible.Allapplicablesafetystandardsincludinglockout/tagoutprocedureshouldbeobserved.

• Neveruseliquidormetallicbasedanti-stickorlubricatingcompoundsonthegaskets.Prematurefailurecouldoccurasaresult.
