Multiquip 1106218001 Joint Washer

The Multiquip 1106218001 Joint Washer is a genuine OEM component designed for Mayco C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pumps. As a direct OEM replacement, this washer is manufactured to the exact material and dimensional specifications required for proper joint sealing in these concrete pump models. Sourced directly through Multiquip's authorized parts network, the 1106218001 ensures the integrity of the joint connection it supports — keeping your pump operating as originally engineered. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Material Specification — Manufactured to the precise material grade and dimensional tolerances required for concrete pump joint applications, where sealing integrity directly affects pump output consistency.
• Direct-Fit Replacement — Engineered to seat and torque exactly as the original, with no reworking of mating surfaces or hardware required during installation.
• Confirmed Fitment — Compatible with C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pump models.
• Maintains Pump Sealing Performance — A correctly functioning joint washer prevents material bypass and pressure loss at the joint interface; a worn or failed washer can cause leakage, pressure drop, and uneven concrete delivery.
• Authorized OEM Supply Chain — Sold by DHS Equipment as an authorized Multiquip parts distributor, ensuring you receive the correct part with full traceability back to the OEM.

A joint washer serves as the sealing element at a mechanical joint connection within the concrete pump's fluid or material circuit. It fills the interface between mating components to prevent pressure loss, material leakage, or contamination ingress at that connection point. When a joint washer wears, compresses beyond its service limit, or fails, the joint loses its seal — leading to visible leakage, reduced pumping pressure, and potential damage to surrounding components if left unaddressed.
