The Multiquip EM14326 O-Ring is a genuine OEM sealing component designed for Mayco cycloidal concrete pump models including C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith. As an OEM part, the part is manufactured to the exact material grade and dimensional specification called out in the original equipment design, ensuring a proper seal every time. Sourced directly through Multiquip's authorized parts network, this O-Ring is the correct replacement for anyone servicing or rebuilding a C30HD-series concrete pump.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compound and durometer specification of the original part, maintaining full sealing integrity under concrete pump operating pressures and fluid exposure.
- Drop-In Replacement — Dimensionally identical to the factory O-Ring, seating correctly in the original groove without modification to adjacent components.
- Broad C30HD-Series Fitment — Confirmed compatible with C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pumps.
- Leak Prevention — A correctly seated O-Ring maintains pressure integrity across pump fluid passages; a cracked or deformed O-Ring leads to fluid leaks, pressure loss, and pump inefficiency.
- Genuine Multiquip OEM Part — Sourced from Multiquip's authorized supply chain, so you receive the exact component specified for your machine rather than an approximated substitute.
An O-Ring is a circular elastomeric seal used throughout concrete pump assemblies to prevent fluid or slurry from leaking past fittings, valve bodies, and ported connections. In a cycloidal concrete pump like the C30HD series, O-Rings are subjected to continuous pressure cycling and exposure to concrete admixtures, water, and hydraulic fluid — conditions that gradually degrade the rubber compound and cause cracking, flattening, or extrusion out of the groove. When an O-Ring fails, the resulting leak can cause pressure drop, contamination of surrounding components, and eventual pump shutdown. Replacing a worn O-Ring with the correct Multiquip EM14326 restores the sealed interface and returns the pump to full operating condition.
