Iphedi yesilinda, eyaziwa nangokuthi i-cylinder liner, itholakala phakathi kwekhanda lesilinda kanye ne-cylinder block. Umsebenzi wayo ukugcwalisa izikhala ezincane phakathi kwekhanda lesilinda kanye nekhanda lesilinda, ukuqinisekisa ukuvalwa okuhle ebusweni obuhlangene, bese kuqinisekiswa ukuvalwa kwegumbi lokusha, ukuvimbela ukuvuza komoya kanye nokuvuza kwamanzi ejazini lamanzi. Ngokwezinto ezahlukene, ama-gasket esilinda angahlukaniswa abe ama-gasket ensimbi - asbestos, ama-gasket ensimbi - ahlanganisiwe kanye nawo wonke ama-gasket ensimbi. Iphedi yesilinda iyisivalo phakathi kwengxenye ephezulu yomzimba kanye nephansi lekhanda lesilinda. Umsebenzi wayo ukugcina isivalo sesilinda singavuzi, ukugcina isipholile kanye namafutha egeleza esuka emzimbeni eya ekhanda lesilinda angavuzi. Iphedi yesilinda ithwala ingcindezi ebangelwa ukuqinisa i-bolt yekhanda lesilinda, futhi ibhekene nokushisa okuphezulu kanye nokucindezela okuphezulu kwegesi yokusha esilinda, kanye nokugqwala kwamafutha kanye nesipholile.
I-gaspad kufanele ibe namandla anele futhi imelane nenjabulo, ukushisa kanye nokugqwala. Ngaphezu kwalokho, kudingeka inani elithile lokunwebeka ukuze kulungiswe ukujiya nokungalingani kobuso obuphezulu bomzimba kanye nobuso obungezansi bekhanda lesilinda, kanye nokuguquka kwekhanda lesilinda lapho injini isebenza.
