The Multiquip 0204102096 is a genuine OEM Packing ST-4100 designed for the ST-4100 swing tube concrete pump. Sourced directly from Multiquip, this packing component meets the original material and dimensional standards required to maintain a proper seal in the pump assembly. It is a direct replacement for the ST-4100, confirming fitment for operators running that machine on the job. Keeping the correct packing in place is essential to sustaining pump output and preventing material bypass within the system.
Key Features
- Genuine OEM Seal Material — Manufactured to the original compound and hardness spec for the ST-4100, ensuring the packing seats and compresses correctly against mating surfaces.
- Drop-In Replacement — Matches the original profile and dimensions of the ST-4100 packing position, allowing straightforward installation without reworking surrounding components.
- Confirmed ST-4100 Fitment — Verified for use on the Multiquip ST-4100 swing tube concrete pump series.
- Sustained Pump Pressure — A properly seated packing maintains consistent hydraulic and material pressure through the pump circuit; worn packing causes pressure loss, material leakage, and reduced output volume.
- Leak Prevention — Correct packing integrity is a front-line defense against concrete or slurry bypass, which can damage downstream pump components and create hazardous conditions around the machine.
Packing seals in a concrete pump create a compression barrier between moving and stationary components within the pump's material circuit. They prevent concrete slurry from bypassing the intended flow path, which is critical for maintaining output pressure and protecting internal pump hardware from abrasive wear. When packing degrades or loses compression, the pump will begin to lose prime, produce inconsistent output, and allow material to migrate into areas that accelerate wear on pistons, cylinders, and valve components — making timely replacement a key part of any routine pump maintenance schedule.
