The Multiquip 1424302001 Oil Seal 12MM-24 X 4.5 is a genuine OEM component designed for ST1 and ST1F submersible pump models. As a factory-authorized replacement, this seal is manufactured to the exact dimensional tolerances required for a proper, leak-free fit in the pump assembly. Verify your model number against ST1 and ST1F applications before ordering to confirm compatibility. Sourced directly through Multiquip's OEM supply chain, 1424302001 delivers the same fit and sealing performance as the original part installed at the factory.
Key Features
- Precision-Dimensioned Sealing Surface — Engineered to the exact 12MM-24 x 4.5 specification, ensuring full contact and compression against mating surfaces to prevent fluid bypass.
- Genuine OEM Construction — Manufactured to Multiquip's original material grade and dimensional standards, delivering the same sealing integrity as the part your pump shipped with.
- Direct-Fit Replacement — Drops into the existing seal seat on ST1 and ST1F submersible pumps without rework or machining to the housing.
- Submersible Application Rated — Engineered to maintain a positive seal under the continuous wet and pressurized conditions that define submersible pump operation.
- Leak Prevention at the Source — A failed or worn oil seal allows fluid migration into the motor housing, accelerating bearing wear and risking motor burnout; replacing it promptly protects the broader pump assembly.
An oil seal creates a dynamic barrier between rotating shaft components and the surrounding housing, retaining lubricating oil on one side while blocking water, debris, and contaminants on the other. In a submersible pump like the ST1 and ST1F, this seal operates under constant exposure to water and pump pressure, making material integrity and dimensional accuracy critical. When an oil seal deteriorates — through wear, compression set, or chemical degradation — lubricant escapes, contaminants enter, and internal components such as bearings and the motor begin to degrade rapidly.
