The Multiquip 5112190080 Upper Sealing Cup D=18 is a genuine OEM component designed for the DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator series. Sourced directly from Multiquip, this sealing cup meets the exact tolerances specified for these units, ensuring a correct, secure fit within the generator assembly. Verify your model code against the fitment list before ordering to confirm compatibility with your specific DCA25 configuration.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact material grade and dimensional specification required for effective sealing in DCA25-series generator assemblies, not a generic approximation.
- D=18 Dimensional Specification — The 18mm diameter sizing ensures this cup seats correctly in its designated bore without adjustment or reworking during installation.
- Broad DCA25 Series Coverage — Fits DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER models, covering multiple variants within the ultra-silent generator lineup.
- Protects Internal Generator Components — A properly functioning sealing cup prevents fluid migration and contamination within the assembly; a worn or cracked cup can allow ingress that leads to accelerated wear of surrounding components.
- Direct OEM Replacement — Listed under Multiquip part number 5112190080 for straightforward parts lookup and confirmation against your service documentation or parts manual.
A sealing cup is a formed seal component used to retain fluid or exclude contaminants within a bore or cavity in a mechanical assembly. In generator applications, it plays a critical role in maintaining the integrity of fluid systems — preventing leaks past shafts or housings and keeping debris from reaching precision internal parts. When a sealing cup degrades, cracks, or loses its compression, fluid loss or contamination can follow, potentially causing damage to components far beyond the seal itself.
