Mu makina a injini, ma gaskets amagwiritsidwa ntchito kusindikiza pakati pa silinda ndi mutu wa silinda, pakati pa poto yamafuta ndi cylinder block, komanso pakati pa chivundikiro cha valve ndi mutu wa silinda. Ntchito yake ndi kuteteza kutayikira kwa mafuta oziziritsira ndi opaka mafuta mkati mwa injini, komanso kuteteza kutayikira kwa mpweya wochuluka-wochokera muchipinda choyaka. Mwachitsanzo, ngati gasket pakati pa yamphamvu chipika ndi yamphamvu mutu kuonongeka, zingachititse ozizira kulowa kuyaka chipinda kapena mafuta ndimeyi, chifukwa injini kutenthedwa, emulsification mafuta, ndi zina malfunctions.

Dongosolo la hydraulic ndi njira yofunika kwambiri yotumizira ma bulldozers, ndipo ma gaskets amagwiritsidwa ntchito kwambiri mmenemo. Ma gaskets osindikizira amafunikira pamalumikizidwe a mapampu a hydraulic, ma hydraulic motors, ma hydraulic cylinders, ndi malo oyika ma valves osiyanasiyana a hydraulic kuti atsimikizire kusindikizidwa kwamafuta a hydraulic. Kuthamanga kwa hydraulic system ndikokwera kwambiri. Ngati gasket yosindikiza ikalephera, imayambitsa kutayikira kwamafuta a hydraulic, zomwe zimapangitsa kuchepa kwa kuthamanga kwa ma hydraulic system, magwiridwe antchito, komanso kulephera kwa zida. Mwachitsanzo, ngati pisitoni yosindikiza pa pistoni ya silinda ya hydraulic yawonongeka, imatha kuyambitsa kutayikira mkati mwa silinda, zomwe zimapangitsa kuti pang'onopang'ono kuwonjezera kapena kulephera kwa ndodo ya pistoni kugwira ntchito bwino.
