Multiquip 86414110 O-Ring Gasket Set (ST61230/ST61460)

The Multiquip 86414110 O-Ring Gasket Set (ST61230/ST61460) is a genuine OEM sealing kit designed for ST4 and ST6 series submersible pumps, including ST41230, ST41460, ST61230, and ST61460 models. As a direct OEM replacement, this set delivers the exact material grade, dimensional tolerancing, and compression ratings required to maintain a leak-free seal throughout the pump assembly. Sourced directly from Multiquip, part number 86414110 ensures you are installing the same sealing components specified at the factory for these submersible pump families.

Key Features

• OEM-Grade Seal Material — Each O-ring in the set is produced to the exact durometer and chemical-resistance spec required for submersible pump service, resisting degradation from prolonged water and debris exposure.
• Complete Set for Full Service — Includes all O-rings and gaskets needed to reseal the pump in a single service event, so no individual pieces need to be sourced separately.
• Confirmed Fitment for ST4 and ST6 Families — Engineered specifically for ST41230, ST41460, ST61230, and ST61460 submersible pump models; drop-in replacement with no adaptation needed.
• Maintains Pump Integrity Under Submersion — A properly seated O-ring set prevents water ingress into the motor housing and stops pumped fluid from bypassing internal sealing surfaces, preserving both efficiency and motor longevity.
• Critical for Safe Electrical Enclosure Sealing — On submersible pumps, failed or worn O-rings can allow water into electrically live areas; replacing with the correct OEM-spec set is essential for safe continued operation.

O-rings and gaskets serve as the primary sealing barriers between the wet end and the motor housing of a submersible pump. They prevent pumped water from migrating into the motor cavity and stop air or fluid from bypassing pump chambers where pressure is required to move flow. When these seals wear, crack, or deform, the pump may lose prime, exhibit reduced output pressure, or allow moisture into the motor — leading to insulation breakdown and premature motor failure. Replacing the full O-Ring Gasket Set at each service interval is the most reliable way to restore the pump's sealed integrity and protect the internal components from water damage.
