O-RingThis O-ring is an aftermarket replacement static seal sized for a specific hydraulic, fuel, or coolant joint on a forklift. Mechanics install a new O-ring at every fitting disassembly because reused seals fail to reseat reliably under operating pressure. The cost of revisiting a job for a weeping fitting far exceeds the cost of the seal itself in labor time. Sold as an aftermarket replacement, contact us to verify dimensions and compound before ordering, since O-rings in identical nominal sizes vary by material chemistry, and the wrong compound choice fails when exposed to operating fluid temperature or chemistry over service hours.Aftermarket replacement part, cross-references original part number AC0350-00140.Need help confirming fit?
