The Multiquip 0228100420 is a genuine OEM Rubber Seal designed for the DCA ultra-silent and super-silent diesel generator series, including DCA70USI, DCA45USI, DCA45SSKU, DCA40SSKU, and related variants. As a direct OEM replacement, this seal is produced to the same specifications as the original component installed at the factory, ensuring a consistent fit within these generator enclosures. It is the correct part for DCA45USI2, DCA45USI4CAN, DCA70USI2, DCA70USI3CAN, DCA40SSKU4i, DCA45SSKU3, and DCA45SSIU4 models. If you are servicing any generator in the DCA ultra-silent or super-silent family, verify your model code against this fitment list before ordering.
Key Features
- Genuine OEM Sealing Material — manufactured to the original rubber compound specification, maintaining the compression and flexibility required for enclosure sealing on DCA-series generators.
- Direct-Fit Replacement — dimensioned to seat exactly as the original, with no trimming or reworking needed during installation.
- Broad DCA-Series Compatibility — fits DCA70USI, DCA45USI, DCA45SSKU, DCA40SSKU, DCA45SSIU4, and multiple CAN-market variants across the ultra-silent and super-silent families.
- Enclosure Integrity — a properly seated rubber seal keeps sound-dampening enclosure panels tight, preserving the low-noise performance these generators are specified for on sensitive jobsites.
- Weatherproofing — maintains the barrier against moisture, dust, and debris entering the enclosure, protecting internal components from environmental exposure.
A rubber seal on a DCA ultra-silent generator forms part of the acoustic enclosure system that gives these units their low sound output. It compresses between panel joints or door frames to close gaps that would otherwise allow noise to escape and outside contaminants to enter. When the seal deteriorates, cracks, or loses its compression set, both the sound attenuation and the weatherproofing of the enclosure are compromised — potentially exposing sensitive electrical and engine components to moisture and allowing noise levels to rise above the generator's rated specification. Replacing a worn seal restores both the acoustic and protective performance of the enclosure.
