The Multiquip 3494 Outer Seal Urethane 1-1/4 OD is a genuine OEM component designed for Essick Mixers and Whiteman Mixers, including the EM120P Series, EM120S Series, WM120PH, and WM120SH. As a factory-sourced part, the 3494 matches the original urethane material grade and dimensional profile specified for these mixer models, ensuring a consistent, properly seated installation. Sourced directly through Multiquip's OEM supply chain, this seal is the correct service part to use when replacing a worn or damaged outer seal on compatible Essick and Whiteman mixer drum assemblies.
Key Features
- Urethane Material Grade: Manufactured from the same urethane compound as the original — resists abrasion and compression set under the wet, aggregate-heavy conditions inside a mixer drum.
- Exact 1-1/4 OD Specification: The 1-1/4 inch outer diameter matches the original housing bore, allowing the seal to seat correctly without shimming or modification.
- Genuine OEM Part: Sourced directly from Multiquip, so the part number, material, and geometry are identical to what shipped with the machine originally.
- Confirmed Fitment: Compatible with Essick EM120P Series, EM120S Series, Whiteman WM120PH, and WM120SH mixer models.
- Drum Integrity Protection: A correctly functioning outer seal prevents mix, moisture, and abrasive slurry from migrating past the drum interface — a failed seal accelerates wear on adjacent bearing and shaft components.
The outer seal on a concrete or mortar mixer forms the barrier between the rotating drum assembly and the external drive components. Its job is to prevent wet mix, cement slurry, and fine aggregate from working their way into the bearing housing and shaft area, where that contamination causes accelerated wear and eventual component failure. A urethane construction is well suited to this environment because urethane resists the abrasive and mildly caustic nature of cement-based materials better than standard rubber compounds. When this seal wears, tears, or loses its compression, mix contamination gets into areas it should never reach, shortening the service life of the surrounding drivetrain components significantly.
