The Multiquip 02041023404 is a genuine OEM O Ring DNO ST-4100 6150 designed for the ST-4100 series concrete pump. As a direct Multiquip OEM component, this o-ring is manufactured to the exact material and dimensional specifications required for a proper seal in the hydraulic or fluid circuit it serves. Confirmed fitment for ST-4100 equipment makes this the right choice when sourcing a replacement seal for your machine.
Key Features
- Genuine OEM Seal Material — Produced to Multiquip's exact compound and durometer specifications, ensuring the correct compression and fluid compatibility for the ST-4100 application.
- Direct Drop-In Replacement — Dimensioned to seat precisely in the original groove without resizing or modification, restoring a leak-free connection quickly.
- Confirmed ST-4100 Fitment — Engineered specifically for the ST-4100 concrete pump, eliminating guesswork when ordering a sealing component for this machine.
- Leak Prevention — A correctly functioning o-ring maintains system pressure and prevents fluid bypass; a worn or cracked seal can lead to pressure loss, fluid contamination, and pump performance degradation.
- Fluid System Integrity — Using the correct OEM seal compound ensures compatibility with the hydraulic or pumping fluid present in the ST-4100, protecting surrounding components from premature wear.
An o-ring is a circular elastomeric seal designed to sit in a machined groove and create a pressure-tight barrier between two mating surfaces or fittings. In a concrete pump like the ST-4100, o-rings are critical throughout the hydraulic circuit and fluid passages — they prevent leaks that would otherwise cause pressure drops, contamination, and unsafe operating conditions. When an o-ring hardens, cracks, or deforms, the seal fails and fluid can bypass, leading to reduced output pressure and potential damage to connected components. Replacing a worn o-ring promptly with the correct OEM part restores system integrity and keeps the pump operating at full capacity.
