The Multiquip EM289041 3" Gaskets are a genuine OEM replacement designed for the C30HD series concrete pumps, including the C30HD, C30HDNI, C30HDG, C30HDZ, C30HDGA, and C30HDN models. Sourced directly from Multiquip, these gaskets deliver the exact material grade and dimensional spec required for a leak-free seal in high-pressure concrete pumping applications. Keeping the correct gasket in place is critical to maintaining output pressure and protecting surrounding components from slurry contamination. If you're servicing any C30HD family pump, verifying you have part number EM289041 ensures you're installing the right seal for the job.
Key Features
- OEM-Grade Sealing Material — Manufactured to Multiquip's original compression and material specifications, ensuring the gasket holds under the cyclic pressure demands of concrete pumping.
- Direct Drop-In Replacement — Engineered to match the original 3" port interface exactly, so the gasket seats correctly without trimming or shimming during reinstallation.
- Broad C30HD Series Compatibility — Confirmed fit for C30HD, C30HDNI, C30HDN, C30HDG, C30HDZ, and C30HDGA concrete pump models.
- Leak Prevention Under Load — A properly seated 3" gasket maintains the sealed circuit between pump components; a worn or damaged gasket allows slurry bypass, pressure drop, and accelerated wear on mating surfaces.
- Pressure System Integrity — In concrete pumping, a failed gasket can result in uncontrolled material discharge at connection points — using the correct OEM gasket is essential for safe operation.
Gaskets in a concrete pump serve as the pressure-sealing interface between pump housings, pipe connections, and valve assemblies. In cycloidal concrete pumps like the C30HD series, these seals must withstand repeated pressure cycles as concrete is pushed through the system — any loss of sealing integrity causes slurry leaks, reduced output, and potential damage to adjacent components. When a gasket degrades or is improperly sized, back-pressure drops and the pump loses efficiency, often requiring a full shutdown to diagnose the source of the leak.
