Key Features
- Genuine OEM Material Grade — Manufactured to the precise hardness and thickness tolerances required for the AW-04 4MM washer position, maintaining correct clamping force under pump operating conditions.
- Direct Drop-In Replacement — Sized and profiled to seat correctly on 4MM fasteners without reworking or resizing the mounting hardware.
- Confirmed ST1 and ST1F Fitment — Verified for Multiquip ST1 and ST1F submersible pump models, so you can order with confidence.
- Preserves Assembly Integrity — A worn or missing washer can allow fasteners to pull through or shift under vibration; replacing it restores proper load distribution across the joint.
- Exact Part Number Match — Supplied as Multiquip part 2750730002, matching the OEM parts list for ST1 and ST1F pumps.
A washer at the AW-04 4MM position distributes the clamping load of a fastener across a wider surface area, preventing the fastener head or nut from embedding into or damaging the mating component during assembly and operation. In a submersible pump environment where vibration and moisture are constant factors, a correctly specified washer helps maintain consistent fastener tension and prevents premature loosening. When a washer deforms, corrodes, or goes missing, fastener joints can become unreliable, leading to misalignment or leaks within the assembly.
