Understanding This Seal Kit
- Catalog identification code: I-U-1
- Wiper code I: insert wiper
- Rod seal code U: U-seal
- Piston seal code 1: no piston seal
The code separates the wiper, rod-seal and piston-seal arrangements so you can compare them with the cylinder being repaired. A wiper helps exclude dirt at the rod entry; rod seals and piston seals fit different locations in the cylinder.
The Hercules catalog lists this code against ORT-RS003540090. Match the kit reference to the original assembly; the code is an identification aid, not a complete packing list.
Fitment Verification
Before ordering, confirm the ORT-RS003540090 reference against your OEM reference number, machine model, cylinder location, bore and rod size, pump/motor series, and serial-number range. Manufacturer names and part numbers are used for identification and fitment reference only. If you are unsure, compare the old parts, measurements, and parts-book callout before installation.
