Multiquip 16223 Insulator Gasket

The Multiquip 16223 Insulator Gasket is a genuine OEM replacement designed for a wide range of Multiquip, Whiteman, and Essick equipment including mixers, saws, generators, pumps, compactors, and roller screeds. As an authorized Multiquip OEM part, the 16223 is produced to the exact material and dimensional specifications of the original component. Compatible equipment includes Whiteman Mixers (WM70, WM120SH, WM120PH), Essick Mixers (EM120S and EM120P Series), MQ Mixers (MC64, MC94), plate compactors (MVH304GSB), gasoline-powered generators (GA3.6HA, GA3.6HZ, GA6HZ), centrifugal pumps (QP402H), trash pumps (QP3TH), masonry saws (MP2H, MP2050, MP2090HP, MP275), street pro flat saws (SP118, SP1CE13H18), arc welders (GAW180HE series), the R2000H roller, and Whiteman roller screeds (WRS5200, WRSPUDF, WRS5200DFPU). Sourcing the correct insulator gasket by part number 16223 ensures a proper seal and protects engine and carburetor components from heat and fuel vapor transfer.

Key Features

• Genuine OEM Material Integrity — Manufactured to Multiquip's original gasket compound and thickness specifications, ensuring correct compression and sealing performance across engine and carburetor interfaces.
• Drop-In Fitment Across Multiple Platforms — Engineered to match the original mounting pattern and flange dimensions, this gasket installs directly without trimming or modification across all listed equipment families.
• Broad Equipment Compatibility — Verified for use across Whiteman Mixers (WM70, WM120), Essick Mixers (EM120), MQ Mixers (MC64, MC94), MVH304GSB compactors, QP402H and QP3TH pumps, GA-series generators, MP and SP saws, GAW180HE welders, R2000H roller, and WRS roller screeds.
• Carburetor Heat Barrier — Functions as a thermal and fuel-vapor barrier between the carburetor and intake manifold, helping maintain consistent fuel mixture quality and protecting carburetor components from radiant engine heat.
• Fuel System Sealing Integrity — A cracked or deteriorated insulator gasket allows unmetered air into the fuel system and can lead to rough idle, lean-running conditions, or difficult starting — replacing it restores proper fuel delivery and engine response.

The insulator gasket sits between the carburetor and the engine intake manifold, creating a sealed, thermally insulating barrier that prevents engine heat from transferring directly into the carburetor body. This thermal separation is critical for stable fuel atomization — excessive heat can cause vapor lock or fuel boiling inside the carburetor, disrupting the air-fuel mixture and making the engine difficult to start or prone to stalling. When the insulator gasket cracks, warps, or loses its compression, it also creates an air leak at the carburetor base, leaning out the mixture and causing erratic performance. Replacing a failed gasket with the correct OEM part restores the sealed interface and thermal break the engine depends on for smooth, consistent operation.
