GasketThis gasket ships as an aftermarket replacement and is a go-to for in-house mechanics keeping fleets running between scheduled rebuilds. It is commonly used between mating engine or hydraulic surfaces to seal oil, coolant, or air, replaced during reseal work or top-end rebuilds, where worn or damaged hardware needs swapping during routine PM or breakdown repair. Keeping pieces like this on the shelf shortens downtime, since component failures often halt a lift truck mid-shift.
