Husqvarna 578108301 Insulator

Product Description

The HUSQVARNA 578108301 is a replacement insulator designed for use in Husqvarna outdoor power equipment. Insulators in this application serve as a thermal and vibration barrier between the carburetor and the engine intake port, helping to reduce heat transfer that can cause fuel vaporization and rough running. This part is installed by small-engine technicians and experienced service professionals as part of carburetor service or engine rebuild procedures on Husqvarna lawn and garden equipment.

This insulator is suited for Husqvarna lawn and garden power equipment applications where the original insulator has cracked, warped, or deteriorated due to heat cycling. Replacement is typically performed during carburetor removal or when diagnosing fuel delivery issues related to heat soak. Proper fitment ensures a sealed, vibration-dampened connection between the carburetor and engine block.

Key Features

• OEM replacement part sourced from Husqvarna for direct-fit installation
• Provides thermal insulation between carburetor and engine intake to reduce heat soak
