A hydraulic system is only as reliable as its seals. Under the punishing pressures and high temperatures of daily excavator operation, even a minor leak can lead to dropped productivity, drifting booms, or catastrophic fluid loss.
We stock a comprehensive, warehouse-ready inventory of high-performance hydraulic seal kits engineered specifically for Kobelco SK series construction equipment — not just a handful of universal O-rings, but complete, application-specific overhaul kits to seal your entire machine from track to bucket.
Complete Cylinder Seal Kits
We stock complete rod, piston, wiper, and backup seals for every cylinder on your Kobelco machine.
- Boom Cylinder Kits
- Arm / Stick Cylinder Kits
- Bucket Cylinder Kits
- Centre Joint (Swivel / Rotary Manifold) Seal Kits
- Main Control Valve (MCV) Seal Kits
Don't let a failing seal leave puddles on the job site or slow down your operation. Give our heavy machinery parts experts your Kobelco machine model, serial number, or the specific cylinder or component part number — and we'll pull the exact direct-fit seal kit from our shelves for prompt dispatch.
