I-GF Coupling iqukethe amahabhu ensimbi amabili anamazinyo egiya anomqhele nangaphandle, ukuvikela okumnyama kwe-Oxidation, axhunywe ngomkhono we-resin yokwenziwa. Umkhono wakhiwe nge-polyamide yesisindo samangqamuzana aphezulu, ufakwe esimweni esishisayo futhi ufakwe okokugcoba okuqinile ukuze unikeze impilo ende yokungakhathaleli. Lo mkhono unokumelana okuphezulu nomswakama womkhathi kanye nezinga lokushisa elisebenzayo elingu -20˚C ukuya ku-+80˚C elinamandla okumelana no-120˚C isikhathi esifushane.
