Understanding This Seal Kit
- Wiper code P: press-in wiper
- Rod seal code UB: U-seal with buffer
- Piston seal code 10: 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.
These terms explain the Hercules identification code shown above. 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 CTC-9T1834K 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.
