Izinciphisi ze-Orifice iyithuluzi elisetshenziselwa ukulawula ukugeleza koketshezi, ngokuvamile elisetshenziswa ezihlokweni zesifutho zamabhodlela eziqholo noma ezinye izitsha eziwuketshezi. Lezi zixhobo ngokuvamile zenziwe ngepulasitiki noma irabha futhi zingafakwa ekuvuleni kwekhanda lesifutho, ngaleyo ndlela kuncishiswe ububanzi bokuvula ukuze kukhawulwe isivinini kanye nenani loketshezi oluphumayo. Lo mklamo usiza ukulawula inani lomkhiqizo osetshenzisiwe, ukuvimbela udoti owedlulele, futhi unganikeza nomphumela onembe kakhudlwana futhi ofanayo wokufutha. Abasebenzisi bangakhetha isinciphisi somsuka esifanele ngokwezidingo zabo ukuze bathole umphumela wokufafaza uketshezi abawufisayo, baqinisekise ukusetshenziswa okusebenzayo nokuhlala isikhathi eside komkhiqizo.
