The Multiquip EM517690 Flex Hose Air Cleaner 2" is a genuine OEM replacement designed for the C30HDG concrete pump. As a direct Multiquip OEM part, the EM517690 is manufactured to the exact dimensions and material specification of the original component, ensuring a correct connection between the air cleaner assembly and the engine intake on C30HDG equipment. Sourced through DHS Equipment as an authorized Multiquip parts distributor, this hose ships as a direct drop-in for the factory-installed unit.
Key Features
- Genuine OEM Material Construction — Produced to Multiquip's original flex hose specification, with the correct 2" inner diameter and flexible wall compound to maintain an airtight seal under engine vibration and heat cycling.
- Direct Intake Connection — Connects the air cleaner housing directly to the engine intake port on the C30HDG with no trimming or adapter fittings needed.
- Confirmed Fitment for C30HDG — Verified OEM fitment for the Multiquip C30HDG Mayco concrete pump; use part number EM517690 to confirm compatibility before ordering.
- Protects Engine Air Intake Integrity — A properly seated flex hose prevents unfiltered air from bypassing the air cleaner, protecting the engine from dust and debris ingestion common on concrete pump worksites.
- Flexible Design Absorbs Vibration — The flexible construction accommodates minor positional shifts between the air cleaner and intake, preventing stress cracks and hose fatigue over extended pump operation.
The flex hose on an air cleaner assembly serves as the conduit between the air filter housing and the engine's intake system. Its job is to deliver a clean, unrestricted airflow path while absorbing the constant vibration generated during engine operation — keeping the connection sealed without cracking or collapsing. When this hose deteriorates, splits, or pulls loose, unfiltered air can enter the engine directly, accelerating wear on internal components and potentially causing engine damage over time on demanding applications like concrete pumping.
