Multiquip D4374100103 Air Cleaner Hose - OEM Replacement Part

The air cleaner hose is a critical component that connects the air filtration system to the engine intake on Multiquip welder units, ensuring clean, filtered air reaches the combustion chamber while maintaining proper air flow and pressure. This hose protects your engine from dust, debris, and contaminants that can cause premature wear, reduced performance, and costly engine damage.

Designed specifically for demanding welding applications, this OEM air cleaner hose is constructed from durable materials that resist heat, oil, and environmental degradation. Regular inspection of air intake hoses is essential preventive maintenance—cracks, splits, or loose connections can allow unfiltered air into the engine, compromising power output and fuel efficiency while accelerating internal wear on cylinder walls and piston rings.

This air cleaner hose is compatible with the following Multiquip welder models:

• DLW-400ESA4
• DLW-400ESA4F
• DLW330X2

Replace this hose at the first sign of deterioration, cracking, or poor fitment to maintain optimal engine protection and performance. Genuine Multiquip OEM part, sold by an authorized dealer.
