The Multiquip 5111290060 Sealing Cup is a genuine OEM component designed for DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, TLG12SPX, and DCA25SSIU-GEER ultra-silent diesel generators. Sourced directly from Multiquip, this sealing cup delivers the exact material grade and dimensional accuracy required for a proper seal in your generator's fluid system. If you're servicing any of the compatible DCA or TLG series units, this is the correct OEM-specified part for the job.
Key Features
- OEM-Grade Seal Material — Manufactured to Multiquip's original material specifications, ensuring the correct compression characteristics and chemical resistance for sustained sealing performance in diesel generator applications.
- Drop-In Installation — Matches the original sealing cup geometry exactly, allowing straightforward installation without reworking the surrounding components or housing.
- Confirmed Fitment — Verified for DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, TLG12SPX, and DCA25SSIU-GEER ultra-silent diesel generator models.
- Prevents Fluid Loss and Contamination — A properly functioning sealing cup maintains fluid containment within the system; a worn or failed cup can lead to leaks, pressure loss, and internal contamination that compromises generator operation.
- Genuine OEM Part — Sold under Multiquip part number 5111290060, this is the same component specified in the original equipment build — not an approximation or generic substitute.
A sealing cup is a soft, cup-shaped seal used to retain fluid and prevent leakage within a pressurized or fluid-filled system. In diesel generator applications, these seals play a critical role in keeping hydraulic, fuel, or coolant passages properly closed and preventing cross-contamination between systems. When a sealing cup degrades — through heat cycling, chemical exposure, or age — it loses its ability to maintain a tight seal, which can result in visible leaks, reduced system pressure, or internal fluid migration that leads to accelerated wear on surrounding components.
