Multiquip 17215 Fitting Nipple 1.25MP Close Galvanized

The Multiquip 17215 Fitting Nipple 1.25MP Close Galvanized is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welder units. As a direct OEM replacement, part 17215 delivers an exact connection match to the original plumbing configuration, ensuring no improvised adapters or field modifications are needed at the fitting point. Sourced directly through Multiquip's authorized parts network, this galvanized close nipple maintains the fluid or fuel line integrity the DLW400ES platform was engineered around. DHS Equipment supplies this part ready for installation on compatible welder models.

Key Features

• Genuine OEM Galvanized Construction — Full galvanized finish provides corrosion resistance suited to the demanding environment of diesel welder plumbing systems.
• 1.25MP Close Nipple Configuration — Short close-pattern length enables tight-clearance installations where standard nipples cannot seat flush against fittings or ports.
• Direct OEM Fitment for DLW400ES Series — Engineered to match the original plumbing specification of DLW400ES, DLW400ESA, and DLW400ESA1 welders without rework.
• Maintains Fluid Line Integrity — A correctly threaded, correctly rated nipple prevents weeping connections and pressure loss that can compromise welder cooling or fuel delivery circuits.
• Verified Multiquip Part Number — Ordering by OEM part number 17215 eliminates the guesswork of cross-referencing generic pipe fittings to a machine-specific plumbing layout.

A close nipple is a short pipe fitting threaded on both ends with little to no unthreaded shoulder between them, allowing two threaded fittings or ports to be joined with minimal spacing. In diesel welder plumbing systems, close nipples are used where space is limited and a direct, rigid connection between two threaded components is required. When a nipple is damaged, corroded, or cross-threaded, the resulting leak or pressure drop can interrupt coolant flow, fuel delivery, or hydraulic circuits, causing the machine to run poorly or shut down entirely.
