Ama-O-rings asetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yekhono lawo lokudala uphawu phakathi kwezindawo ezimbili.Ukukhethwa kwempahla ye-O-ring kuncike ekusetshenzisweni kanye nendawo ezosetshenziswa kuyo. Nazi ezinye izinto ezivamile ezisetshenziselwa ama-O-rings:
I-Nitrile (NBR): Lena into edumile yama-O-rings ngenxa yokumelana kwayo okuhle nowoyela, uphethiloli, namanzi.Iyakwazi ukumelana namazinga okushisa afinyelela ku-100°C.
I-Viton (FKM): I-Viton iyi-elastomer ye-fluorocarbon enokumelana okuhle kwamakhemikhali, ikakhulukazi emazingeni okushisa aphezulu kanye namakhemikhali anokhahlo.Iyakwazi ukumelana namazinga okushisa afinyelela ku-200°C.
I-Silicone (VMQ): Izindandatho ze-Silicone O zaziwa ngokuguquguquka kwazo okuhle kakhulu kanye nokumelana nokushisa okwedlulele, kokubili okuphezulu naphansi.Ziyakwazi ukumelana namazinga okushisa asuka ku -60°C kuya ku-200°C.
I-EPDM iyirabha yokwenziwa enokumelana okuhle kakhulu nesimo sezulu, i-ozone, nemisebe ye-UV.Ivamise ukusetshenziswa ezinhlelweni zangaphandle futhi ingamelana nezinga lokushisa elifinyelela ku-150°C.
I-Neoprene: Izindandatho ze-Neoprene O ziyaziwa ngokumelana kwazo okuhle nowoyela, isimo sezulu kanye ne-ozone.Ziyakwazi ukumelana namazinga okushisa afinyelela ku-100°C.
