I-EPDM O-ring iwuhlobo lwe-seal eyenziwe ngerabha ye-ethylene propylene diene monomer (EPDM).Inokumelana okuhle kakhulu nokweqisa kwezinga lokushisa, ukukhanya kwe-UV, namakhemikhali anokhahlo, okuyenza ifaneleke uhla olubanzi lwezinhlelo zokusebenza zokuvala.Izindandatho ze-EPDM O-ring nazo zinezakhiwo ezinhle zokuvala ugesi futhi zibiza kakhulu uma ziqhathaniswa namanye ama-elastomer.Zivame ukusetshenziswa ekusetshenzisweni okufana nokwelashwa kwamanzi, ama-solar panel, nokucubungula ukudla.Izindandatho ze-EPDM O zitholakala ngosayizi abahlukahlukene futhi zingenziwa ngokwezifiso ukuze zihlangabezane nezidingo ezithile zokuvala uphawu.
