Hydraulic O-RingThis O-ring is an aftermarket replacement, contact us to verify fit before ordering. O-rings seal hydraulic and pneumatic joints throughout a forklift, from lift cylinders and steering valves to fuel system unions, and a single failed ring can drop lift pressure or leak hydraulic oil onto a warehouse floor. Fleet operators and forklift repair shops stock these in bulk because they are the cheapest insurance against unscheduled downtime. The compound and durometer matter, so confirm the application and pressure rating with our parts desk if you are unsure which seal you need.Aftermarket replacement part, cross-references original part number AC34A-69-11280.Need help confirming fit?
