B. Deburring
 Useaknife,plasticpipedeburringtool,orfile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fitting.Failuretochamferthe
edgeofthepipemayremovecementfromthefittingsocket,causing
thejointtoleak.

Thegapmustbelledtoobtainastrong,leak-freejoint.
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.

 Applyprimertothesurfaceofthepipe and tting socket with
anaturalbristlebrush.Thisprocesssoftensandpreparesthe

withouthesitationtothecementingprocedurewhilethesurfaces
arestillwetwithprimer.
E. Application of solvent cement
 • Apply the solvent cement evenly and quickly around the
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.
 • Applyasecondcoatofcementtothepipeend.

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
soholdthejointtogetherforabout15seconds.

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.
