Kubalulekile ukuqonda ukuba zeziphi ii-O-rings kwaye kutheni zilukhetho oludumileyo lwetywina.I-O-ring yinto engqukuva, efana ne-donut esetyenziselwa ukudala itywina phakathi kwemiphezulu emibini kwindawo enoxinzelelo oluphezulu.Xa ifakwe ngokuchanekileyo, i-O-ring seal inokuthintela phantse lonke ulwelo ekubalekeni izikhongozeli kuzo zombini iindawo ezingamanzi kunye negesi.
Izinto eziphathekayo ze-O-rings zixhomekeke kwisicelo sabo, kodwa izinto eziqhelekileyo ze-O-rings ziquka i-nitrile, i-HNBR, i-fluorocarbon, i-EPDM, kunye ne-silicone.Ii-O-rings nazo ziza ngobukhulu obahlukeneyo kuba kufuneka zifakwe ngokuchanekileyo ukuze zisebenze ngokuchanekileyo.Ezi zitywina zibizwa ngokuba zii-O-rings ngenxa yesetyhula okanye "O-shaped" cross-section.Ubume be-O-ring buhlala buhambelana, kodwa ubukhulu kunye nezinto eziphathekayo zingenziwa ngokwezifiso.

Xa sele ifakiwe, i-O-ring seal ihlala isendaweni kwaye ixinzelelwe kwi-joint, yenza isitywina esiqinileyo, esiqinileyo.Ngokufakela okufanelekileyo, izinto eziphathekayo kunye nobukhulu, i-O-ring inokumelana noxinzelelo lwangaphakathi kwaye ithintele naluphi na ulwelo ukuba lubaleke.

Sinomgangatho ohlukeneyo wobungakanani obufana ne-C-1976 / AS568 (umgangatho we-USA ubukhulu) / uchungechunge lwe-JIS-S / C-2005 / i-JIS-P series / i-JIS-G series.
