Cylinder-ready seal kits, direct from the mold
PU and FKM piston and rod seals rated for high-pressure excavator and loader cylinders. Each kit covers the full overhaul—no piecemeal sourcing, no substitutions.
Built for high-cycle cylinder work
PU seals handle up to 400 bar dynamic pressure with strong abrasion resistance—standard fit for excavator bucket and arm cylinders. FKM covers high-temperature rod seal applications to 200°C.
Every compound is batch-tested against dimensional tolerance and Shore hardness before it enters the mold. No substitutions between production runs.
One order. Full cylinder overhaul.
Bundled per cylinder model
Same spec, every batch
Mixed-container ordering
Kits are assembled to match specific excavator and loader cylinder models—rod seal, piston seal, wiper, and O-rings in one SKU. No cross-referencing individual parts.
Mold parameters and compound formulas are locked per SKU. Kit #1 and kit #10,000 seal to the same pressure rating—no drift between production runs.
Combine multiple kit SKUs in one container. We confirm lead time and mix at order stage—directly with the factory, no trading intermediary involved.
