Grease FittingThis grease fitting threads into a chassis, mast, or steering pivot to provide a grease gun coupling for periodic lubrication. PM technicians replace zerks routinely as ball checks fail, hex flats round off, or threads strip from over-torque during lubrication routes. Carrying a sized assortment keeps the PM cart fully stocked. Sold as an aftermarket replacement, contact us to verify thread, taper, and length against your application before ordering, since SAE and metric grease fittings look almost identical on the bench but seal differently in the port, and substituting between them leads to grease bypass past the threads.Aftermarket replacement part, cross-references original part number AC0280-00006.Need help confirming fit?
