The Multiquip 04114350 O-Ring TD 4L2009 is a genuine OEM sealing component designed for the TD4L2009 concrete pump. Sourced directly from Multiquip, this O-ring delivers the exact material grade, durometer, and dimensional tolerancing required to maintain a pressure-tight seal in the pump's hydraulic or fluid circuit. Confirmed to fit the TD4L2009, this is a direct OEM replacement that installs into the same seat as the original with no reworking of the surrounding components. When a seal is compromised, keeping the correct replacement on hand means the pump gets back to work with confidence.
Key Features
- Exact OEM Material Specification — Manufactured to the precise compound and durometer rating required for the TD4L2009's operating pressures, ensuring consistent compression and sealing performance.
- Drop-In Seat Fit — Dimensioned to the original groove geometry so the O-ring seats correctly without stretching, trimming, or modification to the housing.
- Confirmed TD4L2009 Fitment — Verified genuine OEM part for the Multiquip TD4L2009 concrete pump; cross-reference part number 04114350 before ordering to confirm application.
- Leak Prevention at the Source — A correctly installed O-ring keeps fluid contained within the circuit, preventing pressure loss that would otherwise reduce pump output or cause fluid contamination.
- Fuel and Fluid System Safety — On any pump handling pressurized fluid, a failed or swollen O-ring can lead to uncontrolled leaks; using the correct OEM seal maintains system integrity and safe operation.
An O-ring functions as a static or dynamic seal between two mating surfaces, compressing within a machined groove to block the passage of fluid or air under pressure. In a concrete pump like the TD4L2009, O-rings are used throughout the hydraulic system, fluid circuits, and connection points to maintain consistent operating pressure and prevent contamination. When an O-ring degrades — through heat cycling, chemical exposure, or mechanical wear — it loses its ability to maintain compression, leading to leaks, pressure drop, and potential damage to surrounding components.
