Waa muhiim in la fahmo waxa ay yihiin O-rings iyo sababta ay u yihiin doorasho shaabadeed oo caan ah.O-ring waa shay wareegsan, oo u samaysan qaab donut, kaas oo loo isticmaalo in lagu abuuro shaabad u dhaxaysa labada sagxood ee jawiga cadaadisku saaran yahay.Marka si sax ah loo rakibo, shaabadda O-ring waxay ka ilaalin kartaa ku dhawaad dhammaan dareerayaasha ka baxsanaya weelasha ku jira labada dareere iyo gaaska.
Alaabta O-rings waxay ku xiran tahay codsigooda, laakiin agabka caadiga ah ee O-rings waxaa ka mid ah nitrile, HNBR, fluorocarbon, EPDM, iyo silicone.O-rings sidoo kale waxay ku yimaadaan cabbirro kala duwan maadaama ay tahay in si sax ah loogu rakibo si ay si sax ah u shaqeeyaan.Shaabadahan waxa loo yaqaan O-rings sababtoo ah wareegooda ama qaybta iskutallaabta ee "O-qaabeeya".Qaabka O-ring waa mid joogto ah, laakiin cabbirka iyo agabka waa la habeyn karaa.
Marka la rakibo, shaabadda O-ring ayaa sii jiri doonta waxaana lagu cadaadiyaa wadajirka, taas oo samaynaysa shaabad adag oo adag.Ku rakibida saxda ah, walxaha, iyo cabbirka, O-ring wuxuu u adkeysan karaa cadaadiska gudaha wuxuuna ka hortagayaa dareere kasta oo baxsan.
Waxaan leenahay heerka cabbirka kala duwan sida C-1976/AS568(Heerka cabbirka USA)/JIS-S taxane/C-2005/JIS-P taxane/JIS-G taxane.
