O-Ring SealReference AC0040800 is stocked as an aftermarket replacement; we recommend confirming compatibility with your serial number before ordering. Elastomeric o-ring used to seal hydraulic fittings, cylinder ports, valve bodies, and fuel system connections throughout the truck. Sized for common SAE and metric port profiles, the compound choice matters when working with hydraulic oil, LPG, or coolant. Hydraulic shops and PM teams resealing cylinders, axles, and gearboxes during routine overhauls use seals like this on most jobs. A weeping seal slowly drops fluid level and lets contamination into the system, so timely replacement keeps pressure and lubrication where they belong.Aftermarket replacement part, cross-references original part number AC0040800.Need help confirming fit?
