Uhlelo lufaka i-groove kanye nesindebe se-ancular ephethwe omunye we-flange ngephuzu eliphakeme kakhulu ekuxhumaneni nelinye i-flange ukuze kwakhiwe umugqa wokubhala lapho ama-flateses ahlangene. Isimo sokuthi uhlelo luyavuza noma alunaso esimweni nasekunciniseni kwezindebe zomuntu kanye nokuguquguquka kwalo ngesikhathi sokuxhumana. Kulolu cwaningo, ama-flanges amaningana angenazidingo alungiswa ngezimo ezahlukahlukene ze-lip ukuphenya ngesimo sokuxhumana nokubopha uphawu ngokuhlaziya kokuhlola nangokwemvelo. Ukuhlaziywa kukhombisa ukuthi imibandela ingavezwa ngokuya ngokuxineka okukhulu kokuxhumana nosayizi wepulasitiki lapho ama-flanges ahlangene. Ukuhlolwa okuvuthayo kwe-helium kuveza ukuthiI-Gasketless FlangeInokusebenza kangcono kokubekwa uphawu ngokuqhathaniswa nama-gaskets ajwayelekile.
