The Multiquip 956000079 is a genuine OEM O Ring MQC-100 180 designed for the MQC-100 concrete pump. As a direct Multiquip OEM component, it is manufactured to the exact material and dimensional specifications required for proper sealing within the pump assembly. This part is confirmed for use on MQC-100 series concrete pumps, making it a straightforward like-for-like replacement when your existing O-ring shows wear, cracking, or loss of compression.
Key Features
- OEM Elastomer Specification — Manufactured to Multiquip's exact material compound and dimensional tolerances, ensuring correct compression and sealing performance in the MQC-100 pump circuit.
- Drop-In Replacement — Matches the original groove geometry and cross-section of the MQC-100 180 O-ring, so installation seats correctly without modification to the housing or fitting.
- MQC-100 Concrete Pump Fitment — Verified genuine OEM part for the Multiquip MQC-100 cycloidal-driven concrete pump series.
- Leak Prevention — A properly seated O-ring maintains hydraulic and fluid-circuit integrity within the pump; a degraded ring allows fluid bypass, pressure loss, and potential contamination of surrounding components.
An O-ring is a precision-molded elastomeric seal used to prevent fluid or pressure from escaping between two mating surfaces inside the pump. In a concrete pump like the MQC-100, O-rings are found throughout the hydraulic and fluid circuits, where they must maintain a consistent, compression-based seal under operating pressure and temperature cycles. When an O-ring degrades — through cracking, swelling, or flattening — it loses its ability to hold that seal, leading to fluid leaks, pressure drop, and potential damage to adjacent components if not addressed promptly.
