What to Confirm Before Ordering Seals
Hydraulic seals are small parts with expensive consequences when the profile, material, or size is wrong. Confirm the original part number, cylinder application, component location, seal profile, dimensions, and machine details before ordering.
- Manufacturer and machine model or component application.
- Original part number or Hercules reference number when available.
- Rod diameter, bore diameter, groove dimensions, and seal profile.
- Cylinder location, operating environment, and whether the repair needs a complete kit or individual sealing parts.
Application Names Are for Identification
Manufacturer names such as Komatsu, Caterpillar, John Deere, Hitachi, Volvo, Case, Kobelco, Kubota, Parker/Commercial Intertech, Vickers, and others are used for application identification only. WQC Parts uses those names to help customers find the right aftermarket sealing product path.

Sealing-product buyers often research seals together with hydraulic components, service kits, pins and bushings, and machine-specific parts paths.
Common Questions
Can WQC Parts help identify a seal without a part number?
Yes, but photos, dimensions, component details, and machine information are important. The original part number is still the strongest reference.
Are manufacturer names used as OEM claims?
No. Manufacturer names are used for fitment and application identification only.
Need help confirming fitment? Send WQC Parts the Komatsu part number, machine model, serial number, and pivot location. We can help narrow the correct aftermarket replacement path before you order.
