Uma isihlungi sifakwe kulayini kaphethiloli, sibizwa ngokuthi isihlungi sangaphandle; ngokuphambene, isihlungi sangaphakathi sibhekisela kusihlungi esifakwe ngaphakathi kwephampu yamafutha kanye nethangi likaphethiloli. Isihlungi sethangi likaphethiloli noma umkhono waso oyisivikelo ngokuvamile uthathwa njengokulungiswa-mahhala.
Izimoto eziningi ezithunyelwa kwamanye amazwe zisebenzisa i-banjo yokufaka izihlungi zazo zamafutha. Ukuqinisekisa uphawu oluthembekile, ungalokothi usebenzise i-gasket efanayo. Ngisho noma kusetshenziswa i-gasket entsha, kufanele ihlolwe ukuqina ngemva kokuqina. Uma ushintsha ama-O-amaringi kusistimu kaphethiloli, qinisekisa ukuthi angokucaciswa kahle kanye nemodeli, futhi uqinisekise ukunwebeka kwawo kanye nokuba lukhuni kwawo.
Isistimu kaphethiloli-evaliwe inesihlungi sangaphakathi esisodwa kuphela (ngaphakathi kwethangi likaphethiloli). Nakuba konke lokhu-ku{3}}kupompo eyodwa, isihlungi, kanye neyunithi yokudiliva kubiza, kudinga ukulungiswa ngokushesha nangokufanele uma ukugeleza kukaphethiloli kuphazamiseka noma ukusebenza kwenjini kuba sengozini. Futhi, hlola zonke izintambo zikaphethiloli ukuze uthole amaphutha kanye nokuqhekeka kanye nokuma kwe- hose clamp.
