The Multiquip EM807158 Air Filter Rubber Reducer is a genuine OEM component designed for the LS300G hydraulic-driven concrete pump. As a direct OEM replacement sourced through Multiquip's authorized parts network, EM807158 ensures an exact match to the original component specification. This reducer is built to maintain a secure, airtight connection between the air filter housing and the engine intake on LS300G equipment, preserving the integrity of the air filtration system under demanding concrete pumping conditions.
Key Features
- OEM-Grade Rubber Compound — Formulated to resist cracking, compression set, and deterioration from the heat cycles common in concrete pump engine compartments.
- Direct Interface Fit — Mates precisely to the air filter housing and intake neck on the LS300G, seating without gaps that could allow unfiltered air to bypass the filter element.
- Verified LS300G Fitment — Confirmed for Mayco LS300G hydraulic-driven concrete pumps; cross-reference part number EM807158 before ordering to confirm application.
- Protects Engine from Contamination — A failed or cracked reducer allows dust and debris to enter the intake stream, accelerating internal engine wear and compromising pump output.
- Genuine Multiquip OEM Part — Supplied as an authorized replacement, so you receive the same part that was installed at the factory — no guesswork on material grade or dimensional tolerance.
The air filter rubber reducer forms a flexible, sealed transition between the air filter assembly and the engine's air intake. Its role is to maintain an unbroken, debris-free airflow path so the engine receives only clean, filtered air. When this reducer cracks, hardens, or collapses — common results of prolonged heat exposure and vibration — unfiltered air can enter the intake, leading to accelerated cylinder and valve wear, rough running, and eventual engine damage. Replacing a worn reducer promptly is one of the simplest ways to protect the long-term health of the power unit on a concrete pump.
