Multiquip 411040-01 O-Ring

The Multiquip 411040-01 O-Ring is a genuine OEM sealing component designed for ST41230, ST41460, ST61230, and ST61460 submersible pumps. Sourced directly from Multiquip, this O-Ring matches the original material grade and dimensional profile specified for these units, ensuring a proper compression seal every time. It is a direct replacement for worn or damaged O-Rings in these submersible pump models, with no fitting adjustments needed.

Key Features

• OEM-Grade Seal Material — Manufactured to the original compound and durometer specification, delivering the correct compression and chemical resistance for submersible pump service environments.
• Drop-In Replacement — Dimensionally identical to the original, seating into the same groove and mating surface without modification to surrounding components.
• Confirmed Fitment — Verified for ST41230, ST41460, ST61230, and ST61460 submersible pump models.
• Leak Prevention — A properly seated O-Ring maintains the pressure boundary between pump sections; a cracked or flattened ring leads to fluid bypass, loss of prime, and potential motor damage.
• Fluid and Pressure Resistance — Engineered to hold its sealing profile under the continuous hydrostatic pressure and fluid exposure conditions typical of submersible pump operation.

An O-Ring is a precision-molded elastomeric seal that sits in a machined groove and compresses between two mating surfaces to prevent fluid from passing through the joint. In a submersible pump, O-Rings are critical at housing interfaces, port connections, and shaft passages — anywhere water or pumped media could escape the flow path or migrate into protected areas. When an O-Ring ages, it loses elasticity, flattens, or cracks, breaking the seal and allowing leakage that reduces pump efficiency, causes loss of discharge pressure, and can allow water intrusion into the motor housing.
