Key Features
- Genuine OEM Material Integrity — Manufactured to Multiquip's original hardness and temper specifications, so the washer delivers the correct spring tension and bite needed to resist fastener loosening under vibration.
- Direct-Fit Installation — Matches the original bore diameter and outer profile exactly, dropping into place on the same bolt hardware without rework or shimming.
- Broad Multiquip Fitment — Confirmed for QP3TZ and QP2TZ trash pumps and MVH408DZ and MVH308DZ reversible plate compactors, covering multiple product families with a single part number.
- Vibration-Resistant Locking Action — The hardened split design bites into both the fastener face and the mating surface, maintaining clamp load on equipment that operates under sustained vibration and heavy mechanical stress.
- Fuel and Fluid System Safe — Where used in pump assemblies, the lock washer maintains joint integrity in environments exposed to water, fuel, and mechanical cycling, preventing loosening that could lead to leaks or component separation.
A lock washer sits beneath a bolt or nut and uses a split, hardened ring to create friction and mechanical resistance that prevents the fastener from backing out during operation. On equipment like plate compactors and trash pumps — both of which generate significant vibration through normal use — fastener loosening is a real and recurring risk. A worn, flattened, or missing lock washer allows critical bolted joints to work loose over time, which can lead to misalignment, fluid leaks, or structural failure of the assembly it secures. Replacing a compromised lock washer with the correct OEM part restores the joint to its original holding specification.
