The Multiquip 02041023406 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 delivers the correct material grade and dimensional tolerancing needed to maintain a leak-free seal in demanding submersible pump applications. Sourced directly from Multiquip, it is confirmed to fit the ST-4100 series, ensuring compatibility with no guesswork at installation time.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same compound and durometer specification as the original, ensuring consistent compression and sealing performance under submersible operating conditions.
- Exact Dimensional Fit — Matches the original groove geometry of the ST-4100 pump housing, seating correctly without stretching, trimming, or shimming.
- Confirmed ST-4100 Fitment — Verified for the Multiquip ST-4100 submersible pump; use part number 02041023406 to confirm compatibility before ordering.
- Leak Prevention at the Source — A properly seated o-ring keeps pump internals pressurized and dry, preventing water ingress into critical components and maintaining full pumping capacity.
- Genuine Multiquip OEM Part — Supplied through authorized Multiquip distribution channels, so you receive the correct part the first time.
An o-ring is a precision-formed elastomeric seal that sits in a machined groove between two mating surfaces, compressing to create a fluid-tight barrier. In a submersible pump like the ST-4100, o-rings are critical at housing joints and port connections where water pressure is constantly working against the seal. When an o-ring wears, flattens, or cracks, it allows water to bypass the seal — leading to loss of prime, reduced discharge pressure, or water intrusion into motor and mechanical assemblies. Replacing a worn o-ring promptly with the correct OEM part restores the pump's sealed integrity and protects downstream components from damage.
