The Multiquip 02041023405 O Ring DNO ST-4100 6150 is a genuine OEM sealing component designed for the ST-4100 submersible pump. Sourced directly from Multiquip, this O-ring delivers the exact material composition, durometer, and dimensional profile required for a proper seal on ST-4100 series equipment. If you are sourcing replacement seals for your ST-4100 submersible pump, the part is the correct OEM part for the application.
Key Features
- OEM Material Specification — Manufactured to the exact compound and cross-section tolerances required to maintain a leak-free seal in submersible pump applications.
- Drop-In Sealing Fit — Engineered to seat correctly in the designated groove without stretching, trimming, or adjustment during installation.
- Confirmed Fitment — Verified for use on Multiquip ST-4100 submersible pump models.
- Sustained Pump Integrity — A properly seated O-ring prevents water ingress and pressure loss, keeping the pump operating at rated capacity and protecting internal components from contamination.
- Fluid System Safety — A failed or deteriorated O-ring in a submersible pump can lead to seal failure, uncontrolled leakage, and potential electrical hazard in wet environments — using the correct OEM replacement is essential.
An O-ring is a molded elastomeric seal that sits within a machined groove to create a pressure-tight barrier between two mating surfaces. In a submersible pump like the ST-4100, O-rings are critical at housing joints, shaft penetrations, and port connections — any point where water must be kept out of internal components or where pumped fluid must be contained under pressure. When an O-ring degrades, flattens, or cracks, the seal is compromised, allowing water intrusion or pressure bleed-off that reduces pump output and risks damage to motors and bearings. Replacing a worn O-ring promptly with the correct OEM part restores the integrity of the seal and extends the service life of the surrounding assembly.
