The Multiquip 0204102189 Cap ST-4100 is a genuine OEM cap designed for the ST-4100 concrete pump.

If you're servicing or restoring an ST-4100, this is the correct replacement cap for the job.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original cap, ensuring proper sealing and fitment on the ST-4100.
- Direct Drop-In Replacement — Engineered to seat and secure exactly as the factory-installed cap, with no rework or adaptation needed during installation.
- Confirmed ST-4100 Fitment — Verified for use on the Multiquip ST-4100 concrete pump; match your model before ordering to ensure compatibility.
- Maintains System Integrity — A correctly fitted cap keeps internal fluids, pressure, or materials contained, preventing leaks that can interrupt pump operation or contaminate the work area.
- Backed by Multiquip OEM Standards — As a genuine Multiquip part, this part is held to the same quality controls applied to new equipment production, not a generic substitute.
A cap on a concrete pump serves as a closure component — sealing off a port, reservoir, or access point to keep fluids contained and the system operating at the correct pressure or level. When a cap cracks, warps, or fails to seal properly, it can allow fluid loss, contamination, or pressure drop that disrupts pump performance or forces an unplanned shutdown. Replacing a worn or damaged cap promptly with the correct OEM part keeps the pump's system closed and functioning as intended.
