The Multiquip 864 O-Ring and Gasket Set is a genuine OEM sealing kit designed for ST-series submersible pumps, including ST61230, ST61460, ST41230, ST41460, ST6, and ST4 models. As a direct Multiquip OEM part, the 864 O-Ring and Gasket Set delivers the exact material grades, dimensions, and compression tolerances specified for these pumps — ensuring a proper seal every time. If your submersible pump is showing signs of leakage, moisture intrusion, or seal degradation, this set covers the critical sealing points needed to restore full integrity. Sourced directly through an authorized Multiquip distributor, this kit is the straightforward, correct-fit solution for scheduled maintenance or in-field seal replacement.
Key Features
- OEM-Grade Seal Materials — Each o-ring and gasket is manufactured to Multiquip's specified compound and durometer rating, providing the compression and chemical resistance required for continuous submersible pump operation.
- Complete Sealing Coverage — This set addresses multiple sealing points in a single kit, eliminating the need to source individual o-rings or gaskets separately during a rebuild or maintenance service.
- Confirmed ST-Series Fitment — Verified for ST61230, ST61460, ST41230, ST41460, ST6, and ST4 submersible pump models — verify your model code before ordering.
- Leak Prevention Where It Counts — Worn or cracked seals allow water intrusion into motor housings and fluid bypass at critical pump interfaces, leading to rapid mechanical damage; a fresh set restores the pressure boundary and protects internal components.
- Genuine Multiquip OEM Part — Supplied as an authentic Multiquip replacement, part number 864, ensuring correct geometry and material spec without substitution or guesswork.
O-rings and gaskets form the pressure and fluid boundaries between mating surfaces inside a submersible pump — preventing water from bypassing the pump volute, entering the motor cavity, or leaking at housing joints. When these seals degrade due to age, chemical exposure, or mechanical wear, the pump loses efficiency, risks motor damage from moisture ingress, and may fail entirely. Replacing the full o-ring and gasket set as a matched kit ensures every sealing surface is restored at once, which is especially important during pump rebuilds where partial seal replacement can leave aging components behind.
