O-mphete amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuti athe kupanga chisindikizo pakati pa malo awiri.Kusankha kwa zinthu za O-ring kumadalira momwe zidzagwiritsire ntchito komanso malo omwe zidzagwiritsidwe ntchito. Nazi zina zomwe zimagwiritsidwa ntchito popanga mphete za O:
Nitrile (NBR): Ichi ndi chinthu chodziwika bwino cha O-rings chifukwa cha kukana kwambiri mafuta, mafuta, ndi madzi.Imatha kupirira kutentha mpaka 100°C.
Viton (FKM): Viton ndi fluorocarbon elastomer yomwe ili ndi kukana kwamphamvu kwamankhwala, makamaka kutentha kwambiri komanso mankhwala oopsa.Imatha kupirira kutentha mpaka 200 ° C.
Silicone (VMQ): Silicone O-mphete zimadziwika chifukwa cha kusinthasintha kwake komanso kukana kutentha kwambiri, kumtunda ndi kutsika.Amatha kupirira kutentha kuchokera -60 ° C mpaka 200 ° C.
EPDM ndi mphira wopangira womwe umalimbana kwambiri ndi nyengo, ozoni, ndi kuwala kwa UV.Amagwiritsidwa ntchito kwambiri panja ndipo amatha kupirira kutentha mpaka 150 ° C.
Neoprene: Mphete za Neoprene O zimadziwika chifukwa chokana mafuta, nyengo, ndi ozoni.Amatha kupirira kutentha mpaka 100 ° C.
