The Multiquip EM27868 Reducer 6" x 4" C30HD Weld On Type is a genuine OEM component designed for the Mayco C30HD concrete pump. This weld-on style reducer transitions the discharge line from a 6-inch to a 4-inch diameter, and as a direct OEM part it matches the original geometry and material spec of the unit it replaces. Sourced directly through Multiquip's authorized parts network, EM27868 is the correct replacement for C30HD operators looking to restore their pump line to proper working order.
Key Features
- Genuine OEM Construction — Manufactured to the same material grade and wall thickness as the original, ensuring the reducer handles the pressure demands of concrete pumping without premature wear or failure.
- Weld-On Design — Engineered to be welded directly into the discharge line, providing a permanent, leak-free connection that holds up under continuous pumping cycles.
- 6" to 4" Line Transition — Delivers the correct diameter reduction for C30HD pump line configurations, maintaining consistent concrete flow velocity through the system.
- Confirmed C30HD Fitment — Verified for use on the Mayco C30HD concrete pump, so you can order with confidence that this part is the right part for your machine.
- Sustained Output Performance — A correctly fitted reducer keeps concrete moving smoothly through the line; a worn or compromised reducer causes pressure loss, blockages, and uneven pour rates that slow the job.
A reducer in a concrete pump line serves as the transition fitting between two different pipe diameters, controlling how concrete flows from a larger feed section into a narrower discharge section. Maintaining the correct internal geometry at this transition point is critical — any gap, misalignment, or erosion allows concrete to aggregate at the joint, increasing the risk of line blockages and pressure spikes. When a reducer cracks, erodes, or develops voids at the weld, pump output becomes inconsistent and the line becomes vulnerable to failure under operating pressure.
