Multiquip EM402413 Tension Washer with Slot

The Multiquip EM402413 Tension Washer with Slot is a genuine OEM component designed for MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 series fireproofing pump and mixer equipment. As a direct Multiquip OEM part, EM402413 is manufactured to the exact specifications required for correct installation and consistent performance in your machine. Sourced directly through authorized Multiquip distribution, this washer is a dependable choice when servicing or rebuilding affected assemblies on compatible MG30 models.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact material and dimensional specifications, ensuring the slotted profile seats and tensions correctly within the assembly.
• Slotted Design for Precise Engagement — The integrated slot allows the washer to lock into position during installation, preventing rotation and maintaining consistent clamping load under operational stress.
• Broad MG30 Series Compatibility — Confirmed fitment across MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 models, covering both fireproofing pump and mixer configurations.
• Maintains Fastener Preload Integrity — A correctly functioning tension washer preserves the clamping force on critical joints; a worn or missing washer can allow fastener loosening under vibration, leading to premature component failure.
• Direct OEM Replacement — Part number EM402413 cross-references directly to the original Multiquip bill of materials, so the part installs in place of the original without modification.

A tension washer with a slot is a specialized fastening component used to maintain consistent preload on bolted or shaft-mounted assemblies. The slotted feature locks the washer rotationally against a mating tang or keyway, preventing it from spinning free under vibration or torque — a common failure point in pumping and mixing equipment that operates under continuous mechanical load. When a tension washer wears out or is lost during service, fasteners in the assembly can work loose over time, which may result in misalignment, accelerated wear on surrounding components, or unexpected downtime during operation.
