Key Features

• Genuine OEM Material Grade — sourced directly from Multiquip, this plastic washer meets the same material and dimensional tolerances as the original production part, ensuring correct compression and load distribution within the assembly.
• Drop-In Installation — engineered to the original profile and bore size, this washer seats correctly without trimming, shimming, or adapting to fit.
• Confirmed GAW180HE Series Fitment — verified for GAW180HE, GAW180HEA, and GAW180HE1 gasoline arc welder/generator models.
• Maintains Assembly Integrity — a correctly fitted washer distributes fastener load evenly, preventing surface damage, fastener pull-through, and loosening under vibration during generator operation.
• Exact Part Number Reference — order by part number A9311100004 to ensure you receive the correct washer for your specific GAW180HE model variant.

A plastic washer acts as a load-distributing spacer or insulating barrier between fasteners and the surfaces they secure within an assembly. In equipment like the GAW180HE arc welder/generator, washers prevent metal-to-metal contact, reduce surface wear at mounting points, and help maintain consistent clamping force across components subject to vibration. When a washer becomes cracked, deformed, or missing entirely, the fastener it supports can loosen prematurely or cause damage to the surrounding housing or panel material.
