The Multiquip 8702037003 is a genuine OEM Air Cleaner Hose designed for the DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welder series. As a direct OEM replacement, this hose meets the original design requirements for the air intake system on these machines, ensuring a correct, secure connection between the air cleaner and the engine. Sourced directly through Multiquip's authorized parts network, the 8702037003 is the recommended service replacement for maintaining proper air filtration on your DLW300 series welder.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications for the DLW300 series air intake path, ensuring correct hose flexibility, wall thickness, and connection integrity.
- Direct-Fit Replacement — Engineered to seat precisely on the air cleaner outlet and engine intake port of the DLW300ES, DLW300ESA, and DLW300ESA1, with no trimming or adaptation needed at installation.
- DLW300ES Series Compatibility — Confirmed fitment for DLW300ES, DLW300ESA, and DLW300ESA1 Multiquip diesel light welders — verify your model before ordering.
- Protects Engine Air Supply — A properly seated air cleaner hose maintains an unbroken, sealed path from the air cleaner to the engine intake. A cracked or loose hose allows unfiltered air into the engine, accelerating internal wear and compromising combustion quality.
- Authorized Replacement Part — Carrying part number 8702037003, this hose is the correct OEM-specified component for scheduled maintenance or hose replacement on DLW300 series equipment.
The air cleaner hose connects the air filtration assembly to the engine's intake system, forming a sealed passage that ensures only clean, filtered air reaches the combustion chamber. On diesel-powered equipment like the DLW300ES welder series, a damaged or deteriorated hose can allow dust, debris, and contaminants to bypass the air filter entirely, leading to accelerated cylinder and piston wear. Replacing a cracked or collapsed hose promptly keeps the engine breathing correctly and maintains consistent power output during welding operations.
