The Multiquip 00178 is a genuine OEM Pipe RW-1402 designed for DLW series diesel light welders, including the DLW400ESA4, DLW330X2, DLW500ESA4, DLW400ES/ESA/ESA1, and DLW300ES/ESA/ESA1. As a direct Multiquip OEM component, part 00178 is manufactured to the same standards as the original, ensuring a correct, hassle-free installation in your machine. DHS Equipment sources this part directly through authorized channels so you can trust you're getting the right component for your DLW welder.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring the pipe seats and seals exactly as the original did in production.
- Direct-Fit Replacement — Part number 00178 installs into compatible DLW series machines using the original mounting points and connections, with no reworking of surrounding components.
- Broad DLW Series Compatibility — Confirmed fitment across DLW400ESA4, DLW330X2, DLW500ESA4, DLW400ES/ESA/ESA1, and DLW300ES/ESA/ESA1 diesel light welders.
- Sustained Fluid or Gas Flow — A correctly functioning pipe maintains uninterrupted routing of fluid or gas through the system; a damaged or corroded pipe can cause leaks, pressure loss, or system contamination that sidelines your welder.
- Authorized OEM Sourcing — Sold by DHS Equipment through authorized Multiquip distribution, so the part number, fitment data, and OEM designation are verified before it ships.
The Pipe RW-1402 serves as a routed conduit within the DLW series diesel light welder's internal system, carrying fluid, coolant, or gas between components along a fixed path. Maintaining the integrity of this pipe is critical to keeping pressure and flow consistent throughout the machine's operating cycle. When a pipe of this type cracks, corrodes, or develops a leak, it can cause fluid loss, pressure drop, or contamination in connected systems — leading to reduced welder performance or unplanned downtime.
