181572 - Miller 181572 Fuel Tank Grommet Seal

Genuine Miller 181572 Fuel Tank Bushing for Engine Driven Welders

The Miller 181572 Bushing is a critical component in the fuel system of select Miller engine-driven welding machines. Designed as a specialized grommet, this part serves as the interface seal between the fuel tank wall and the fuel shut-off valve or pickup tube fitting. Over time, exposure to hydrocarbon fuels, engine heat, and environmental ozone can cause rubber components to harden, crack, or shrink. A compromised bushing is a primary cause of fuel leaks, which not only leads to fuel wastage but presents a significant safety hazard in industrial environments where sparks and heat are prevalent.

Manufactured to Miller Electric's precise engineering standards, this OEM part ensures exact dimensional compatibility with the fuel tank port. Unlike generic rubber grommets that may not withstand the specific chemical composition of modern fuels (including ethanol blends), the 181572 bushing is formulated from high-grade, fuel-resistant elastomers. This material choice ensures long-term durability and retention of elasticity, which is vital for maintaining a tight seal under the constant vibration of a running engine. The bushing also acts as a vibration isolator, reducing the mechanical stress transferred from the vibrating engine and chassis to the rigid fuel fittings, thereby preventing fatigue cracks in the fuel lines or tank itself.

Maintenance professionals understand that using genuine OEM parts is essential for maintaining the reliability and safety certification of industrial equipment. This bushing is designed for straightforward installation, pressing securely into the tank opening to create a compression seal around the inserted fitting. It is a direct replacement for the original factory part, eliminating the guesswork associated with sizing universal grommets. Whether performing a routine service interval or repairing a detected leak, the Miller 181572 provides the assurance of quality and performance expected from Miller Electric components.

Regular inspection of fuel system components is recommended for all engine-driven equipment. If signs of weeping, cracking, or brittleness are observed around the fuel tank fittings, immediate replacement with this genuine Miller bushing is the standard repair procedure to restore system integrity.
