The Multiquip P0073-516R is a genuine OEM Tube Insulator 3 In. designed for the DCA Super-Silent and diesel-powered generator series, including DCA150SSJU4F3, DCA180SSJU4F3, DCA400SSI4F, DCA400SSI4F3, DCA600SSV4F3, and DCA70SSIU4F models. As a direct OEM part, P0073-516R is manufactured to the exact material and dimensional standards of the original component it replaces. Sourced directly through an authorized Multiquip parts channel, this insulator ensures correct installation without guesswork or fitment concerns. DHS Equipment stocks genuine Multiquip replacement parts to keep your generator running at full capacity.
Key Features
- Genuine OEM Material Integrity — Manufactured to the original insulation grade and wall thickness required for exhaust or fluid tube isolation in DCA-series generators — not a generic substitute.
- Drop-In Installation — Matches the original 3-inch tube diameter exactly, seating securely in the same mounting position as the factory part for a straightforward swap.
- Broad DCA Series Compatibility — Confirmed fit across DCA70SSIU4F, DCA150SSJU4F3, DCA180SSJU4F, DCA180SSJU4F3, DCA400SSI4F, DCA400SSI4F3, DCA600SSV4F3, and related 60 Hz variants.
- Thermal and Vibration Protection — Maintains proper separation between the tube and surrounding components, preventing heat transfer, abrasion, and contact wear that can lead to premature line failure on high-run generators.
- Electrical and Heat Safety Compliance — Correct insulation at tube routing points is critical in generator enclosures where exposed surfaces and heat sources are in close proximity; using the specified OEM part preserves designed clearances.
A tube insulator is a protective sleeve or collar fitted around a pipe or tube run inside the generator enclosure to prevent direct contact between the tube and structural panels, heat sources, or electrical components. In a generator application, tubes routed through tight enclosures are exposed to constant vibration and elevated temperatures — without proper insulation, the outer surface of the tube can wear through, transfer heat to adjacent components, or create unsafe contact points. Replacing a worn or damaged tube insulator with the correct OEM part restores the designed separation and protects the integrity of the surrounding assembly.
