This cap is a straightforward service item that keeps your Mayco concrete pump operating safely and correctly between jobs.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original exhaust cap, ensuring a secure, lasting seal on the exhaust port.
- Direct-Fit Replacement — Engineered to thread or press directly onto the 2-1/4 in. exhaust opening with no rework or adaptation needed at installation.
- Confirmed Fitment — Verified OEM fit for LS40D and LS300 hydraulic-driven concrete pump models in the Mayco/Multiquip lineup.
- Exhaust Port Protection — Caps the exhaust outlet when the pump is idle or in transport, blocking debris, moisture, and contaminants from entering the exhaust system.
- Correct Sizing Matters — A properly sized 2-1/4 in. cap maintains a snug fit; an ill-fitting cap can back out during transport or allow water ingress that accelerates internal corrosion.
An exhaust cap covers and seals the exhaust outlet on a concrete pump when the machine is not running. Its primary role is to prevent water, mud, and construction debris from entering the exhaust system during transport, storage, or downtime on the jobsite. When an exhaust cap is missing or cracked, moisture can work its way into the muffler and exhaust manifold, leading to premature corrosion and potential back-pressure issues when the engine is restarted.
