The Multiquip 0204102340 is a genuine OEM O Ring Kit ST-4102 4104 6152 6154 designed for ST-4102 series concrete pumps. As a factory-sourced component, it delivers the correct material grade and dimensional tolerances needed to maintain a reliable seal within the pump's hydraulic and fluid circuits. This kit is confirmed for ST-4102 equipment and is the direct OEM replacement specified for that platform. Sourcing the genuine Multiquip 0204102340 ensures your pump is restored with seals that meet the original engineering requirements.
Key Features
- Correct Seal Material and Geometry — Genuine OEM compound and cross-section dimensions matched to ST-series pump tolerances, ensuring proper compression and sealing performance across all included ring positions.
- Complete Multi-Position Kit — Covers O-ring positions for ST-4102, 4104, 6152, and 6154 configurations in a single kit, so all critical sealing points are addressed in one service interval.
- Drop-In Installation — Each ring in the 0204102340 kit seats into existing grooves without machining or modification, supporting a straightforward rebuild or maintenance procedure.
- ST-4102 Concrete Pump Fitment — Engineered specifically for Multiquip ST-4102 swing-tube concrete pumps, keeping the pump operating within its designed pressure and flow parameters.
- Leak Prevention at Critical Points — Worn or compromised O-rings in a concrete pump allow pressure loss and fluid bypass; replacing them with the correct OEM kit restores full pumping efficiency and prevents material contamination.
O-rings in a concrete pump form the primary seals between pressurized hydraulic and fluid passages, preventing leaks at cylinder ports, valve housings, and pipe connections. When these seals degrade — through wear, chemical exposure, or heat cycling — the pump loses pressure integrity, resulting in reduced output, visible leaks, and potential damage to surrounding components. Replacing the full O-ring kit at service intervals is essential to keeping the pump delivering concrete at consistent volume and pressure.
