The Multiquip 03133200 Washer ST45 is a genuine OEM washer designed for the ST45 concrete pump.

Sourced direct from Multiquip, this washer is the right choice when maintaining or rebuilding your ST45 pump.
Key Features
- Genuine OEM Material Spec — Manufactured to the exact hardness and dimensional tolerances required for proper clamping load and sealing performance in hydraulic and mechanical assemblies.
- Direct Drop-In Replacement — Matches the original mounting bore and outer diameter of the ST45 application, slotting into position without reworking surrounding hardware.
- Confirmed ST45 Fitment — Verified for use on the Multiquip ST45 concrete pump; check your parts manual to confirm the correct installation point before ordering.
- Maintains Clamping Integrity — A properly fitted washer distributes fastener load evenly across mating surfaces, preventing bolt loosening, surface damage, and fluid or pressure leaks over time.
- Supports Full Service Life — Using the correct OEM washer during rebuilds and preventive maintenance helps preserve thread integrity and keeps assemblies torqued to specification longer.
A washer may be a small component, but it plays a critical role in any bolted assembly. It distributes the clamping force of a fastener across a wider surface area, protecting softer mating surfaces from damage and preventing bolts or nuts from loosening under vibration — a constant factor in concrete pumping equipment. When a washer is worn, deformed, or the wrong size, fastener preload drops, which can lead to joint movement, leaks, or accelerated wear on surrounding components. Using the correct OEM-spec washer keeps every bolted joint on the ST45 performing exactly as designed.
