Q1: Can I use an aftermarket hydraulic seal kit instead of OEM?
Yes. High-quality aftermarket hydraulic seal kits are designed to meet or exceed OEM specifications. In many cases, they perform just as well while costing significantly less. The key is to match the correct part number, machine model, and seal dimensions.

Q2: How do I know if I ordered the right hydraulic seal kit?
Before placing an order, double-check:

• The part number from your cylinder or manual.

• The machine brand and model (e.g., Cat 320, Komatsu PC200, John Deere 210).

• The seal dimensions (ID, OD, and height).
  If all three match, you can be confident you’ve got the correct replacement hydraulic seal kit.
