The Multiquip 0228900475 is a genuine OEM Rubber Seal designed for DCA-series ultra-silent and super-silent diesel generators including the DCA36SPXU4F, DCA45SSIU4F, DCA45USI, DCA70USI, and DCA70USI2. As a direct OEM replacement, this seal is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, consistent fit within the generator enclosure or engine assembly. Sourced directly through Multiquip's authorized parts network, the part is the right choice when maintaining your generator to its original operating condition. DHS Equipment stocks genuine Multiquip parts so you can get what you need and get back to work.
Key Features
- Genuine OEM Material Integrity — Manufactured from the same rubber compound as the original, ensuring correct compression characteristics and resistance to heat, vibration, and environmental exposure typical of diesel generator operation.
- Direct Enclosure or Engine Fit — Engineered to seat precisely within the original groove or mating surface, eliminating gaps that can compromise weatherproofing or acoustic performance on super-silent and ultra-silent units.
- Broad DCA-Series Compatibility — Confirmed fit for DCA36SPXU4F, DCA45SSIU4F, DCA45USI, DCA70USI, DCA70USI2, and DCA70USI3CAN generator models.
- Enclosure Sealing Performance — A properly functioning rubber seal maintains the integrity of the generator's sound-attenuating enclosure; a degraded or missing seal allows noise, moisture, and debris ingress that can affect both acoustic ratings and internal component longevity.
- Weatherproofing Compliance — On generator sets rated for outdoor use, maintaining an intact seal is essential to preserve ingress protection ratings and protect sensitive electrical components from moisture infiltration.
A rubber seal on a super-silent or ultra-silent generator serves as the barrier between the outer enclosure panels and internal components, blocking the entry of water, dust, and airborne debris while also contributing to the unit's noise-dampening performance. When the seal degrades — through age, heat cycling, or UV exposure — it loses its ability to compress and conform to mating surfaces, allowing gaps to form. Those gaps can let moisture reach alternator windings and control boards, and they allow sound to escape, eroding the low-noise characteristics these generator series are specifically engineered to deliver. Replacing a worn seal promptly with the correct OEM part restores both protection and acoustic performance.
