O-RingReplacement o-ring for forklifts and material handling equipment using OE reference AC270780. This o-ring seals a hydraulic or pneumatic joint on the lift truck and is replaced any time the joint is opened for service. Forklift technicians at distribution centers, rebuilders, port operators, and rental houses use this interchange to keep older units serviceable at a sensible price point on out of warranty equipment. An aftermarket cross keeps repair budgets in line on older or out of warranty equipment where running OE only parts no longer makes economic sense for the operator or the fleet. Match the OE number to the unit's parts manual before purchase.Aftermarket replacement part, cross-references original part number AC270780.Need help confirming fit?
