Isiteshi se-capping singenye yezingxenye ezibalulekile zephrinta, futhi umthwalo wayo omkhulu ukuvikela umlomo wombhobho. Uma umshini ungasetshenziswa isikhathi eside ngemva kokuma, umlomo wombhobho uzohlala esitakini sikayinki, ngaleyo ndlela uvimbele ngempumelelo ukuvaleka okubangelwa ukufiphala kukayinki ebusweni bombhobho.

Isiteshi se-capping kufanele sishintshwe njalo ngemva kokusetshenziswa isikhathi esithile. Uma kungenjalo, izothinta ukusetshenziswa okuvamile kwephrinta. Isiteshi se-capping sixhumene noyinki isikhathi eside futhi sinempilo yesevisi ethile. Ngokuhamba kwesikhathi, izoguga, ibangele ukuthi umlomo wombhobho kanye nesiteshi sokuvala kuxhunywe ngokukhululekile, kubangele ukuvuza komoya futhi kuphazamise inqubo yokuphrinta yephrinta.

Amaphrinta amanje athuthukise isiteshi se-capping, ukuze kungakhathaliseki ukuthi umshini umisiwe noma usebenza, isiteshi se-capping singakwazi ukuhlanza ngokugcwele i-nozzle, engaqinisekisi kuphela ukukhishwa okuphezulu kwephrinta, kodwa futhi kuvimbela ukuvala nokwandisa impilo yayo yesevisi.
