Frequently Asked Questions

A U-Cup is a dynamic seal whose “U” profile maintains contact with the rod/piston under pressure, helping prevent fluid bypass and preserving consistent output.

Check your model’s parts list/IPC for part 102417. If it’s listed by number and description (Packing, U-Cup), it’s the correct replacement. If uncertain, share your model & serial with support for verification.

Replace at the first signs of leakage, pressure drop, inconsistent output, or as part of your scheduled maintenance interval after a rebuild/service cycle.

No. Use the exact OEM-specified part number. Geometry (ID/OD/height) and material are tailored to your pump’s tolerances; substitutions risk leaks and premature wear.

Typically no special tools beyond basic hand tools and soft picks, but always follow the model-specific service manual. Avoid sharp tools that could nick the sealing lip.
