The Multiquip 02041023408 O Ring DNO ST-4100 6150 is a genuine OEM sealing component designed for the ST-4100 submersible pump. As a direct OEM replacement, this O-ring is manufactured to the original specification, ensuring a proper compression fit within the pump assembly. Sourced directly through Multiquip's authorized parts network, 02041023408 is the correct service part for ST-4100 pump maintenance and seal replacement work.
Key Features
- Genuine OEM Seal Material — Manufactured to the original compound and durometer spec, delivering the correct compression and chemical resistance for submersible pump service conditions.
- Drop-In Replacement — Matches the original groove dimensions and cross-section of the ST-4100 pump, seating correctly without modification to mating surfaces.
- Confirmed ST-4100 Fitment — Verified for use on the Multiquip ST-4100 submersible pump; check your model plate before ordering to confirm compatibility.
- Leak Prevention — A correctly seated O-ring maintains the pump's internal pressure envelope, preventing fluid bypass that would reduce pumping efficiency and allow contamination to enter sealed cavities.
- Fluid System Integrity — In submersible pump applications, a failed or degraded O-ring can allow water intrusion into motor or bearing housings, leading to accelerated wear and pump failure — making timely O-ring replacement a critical service step.
An O-ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces, creating a pressure-tight barrier that prevents fluid from leaking past the joint. In a submersible pump like the ST-4100, O-rings are used at critical interface points — such as end caps, volute casings, and access covers — to keep pumped fluid contained within the flow path and prevent external water from entering protected internal components. When an O-ring hardens, cracks, or is cut during disassembly, the seal is lost and the pump will leak or allow contamination in, shortening the service life of bearings and motor windings significantly.
