B. Deburring
 Useaknife,plasticpipedeburringtool,orletoremoveburrsfromthe
endofsmalldiameterpipe.Besuretoremoveallburrsfromaroundthe
insideaswellastheoutsideofthepipe.Aslightchamfer(bevel)ofabout
10°-15°shouldbeaddedtotheendtopermiteasierinsertionofthepipe
intotheendofthetting.Failuretochamfertheedgeofthepipemay

D. Inspection, cleaning, priming
 Visuallyinspecttheinsideofthepipeandttingsocketsandremove
alldirt,greaseormoisturewithacleandryrag.Ifwipingfailstoclean
thesurfaces,achemicalcleanermustbeused.Checkforpossible
damagesuchassplitsorcracksandreplaceifnecessary.

E. Application of solvent cement
 • Applythesolventcementevenlyandquicklyaroundoutsideofthe
pipeatawidthalittlegreaterthanthedepthofthettingsocket.
 • Applyalightcoatofcementevenlyaroundtheinsideofthe
ttingsocket.Avoidpuddling.

F. Joint assembly
 Workingquickly,insertthepipeintothettingsocketbottomand
givethepipeorttinga1/4turntoevenlydistributethecement.
Donotcontinuetorotatethepipeafterithashitthebottomofthe
ttingsocket.Agoodjointwillhavesufcientcementtomakea
beadallthewayaroundtheoutsideofthettinghub.Thetting
willhaveatendencytoslidebackwhilethecementisstillwet

G. Cleanup and joint movement
 Removeallexcesscementfromaroundthepipeandttingwitha
drycottonrag.Thismustbedonewhilethecementisstillsoft.
 Thejointshouldnotbedisturbedimmediatelyafterthecementing
procedure,andsufcienttimeshouldbeallowedforpropercuring
ofthe joint. Exactdrying timeis difcultto predict becauseit
dependsonvariablessuchastemperature,humidityandcement
integrity.Formorespecicinformation,youshouldcontactyour
solventcementmanufacturer.
