The Multiquip EM801790 Gasket is a genuine OEM gasket designed for the LS450 concrete pump. As a direct OEM replacement, this gasket is manufactured to meet the original specifications of the LS450, ensuring a proper, leak-free seal right out of the box. Sourced directly through authorized Multiquip channels, this is the same part that goes into new equipment — giving you full confidence in fitment and durability.
Key Features
- OEM-Grade Sealing Material — Engineered to the same material composition and compression tolerances as the original, ensuring consistent sealing performance under the pressures and temperatures generated by concrete pump operation.
- Drop-In Installation — Matches the original mounting profile and dimensions of the LS450, allowing straightforward installation without rework or trimming.
- Confirmed LS450 Fitment — Verified for use with the Multiquip LS450 hydraulic-driven concrete pump series.
- Leak Prevention Where It Counts — A degraded or failed gasket on a concrete pump can cause fluid loss, pressure drop, and contamination of surrounding components. A fresh OEM gasket restores the integrity of the sealed joint and maintains proper pump output.
- Genuine Multiquip OEM Part — Part number this part is an authorized Multiquip component, ensuring the correct spec is met every time and protecting the performance of your LS450.
A gasket forms a compressive seal between two mating surfaces — such as pump housings, fluid passages, or cover plates — preventing fluid or pressure from escaping the joint. On a concrete pump like the LS450, maintaining that seal is critical to sustaining consistent hydraulic pressure and keeping the pumping system operating cleanly. When a gasket hardens, cracks, or is compressed beyond its limit, it allows fluid to bypass the joint, which can lead to pressure loss, external leaks, and accelerated wear on surrounding components.
