The Multiquip EM14407 is a genuine OEM O-Ring designed for a wide range of Multiquip and Mayco concrete pump models, including the C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, LS-40, LS40D, LS40TD, LS50TD, LS60TD, LS300, LS300G, LS300GK, LS300P, LS400, LS450, LS500, LS600, LS600P, and ST-45HRM series. As a genuine OEM component, the part is manufactured to the exact material and dimensional standards specified for these machines, ensuring a proper seal every time. DHS Equipment stocks this part to help keep your concrete pump operating at full capacity with no guesswork on fitment.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact durometer and dimensional tolerances specified for Multiquip and Mayco concrete pump hydraulic and fluid circuits, ensuring a consistent, leak-free seal under pump operating pressures.
- Direct-Fit Replacement — the part installs directly into the original O-Ring groove with no trimming, stretching, or adaptation required, maintaining correct compression and sealing contact.
- Broad Concrete Pump Compatibility — Confirmed fitment across C30HD, LS-40, LS300, LS400, LS450, LS500, LS600, ST-45HRM, and related Mayco concrete pump series.
- Protects Against Fluid Leaks — A failed or degraded O-Ring in a concrete pump can allow hydraulic fluid or slurry to bypass sealing surfaces, causing pressure loss and contamination; the part restores proper circuit integrity.
- Correct Material Grade — Sourced directly from Multiquip, this O-Ring is produced in the compound and hardness grade specified for the demanding pressure and fluid exposure conditions found in concrete pump applications.
An O-Ring is a precision sealing component used throughout a concrete pump's hydraulic system and fluid circuits to prevent leakage between mating surfaces, fittings, and ports. In a high-pressure application like a concrete pump, even minor O-Ring degradation — caused by heat, pressure cycling, or chemical exposure — can result in fluid bypass, loss of hydraulic pressure, or contamination that affects pump output and consistency. Replacing a worn or damaged O-Ring promptly with the correct OEM part restores the sealed system to proper operating condition and prevents more extensive damage to surrounding components.
