The Multiquip EE61039 DEF Tank Cap is a genuine OEM DEF Tank Cap designed for the Super-Silent generator series. As a direct OEM replacement, this cap is manufactured to the exact specifications of the original component, ensuring a proper seal on the diesel exhaust fluid tank. DHS Equipment stocks this part to keep your Super-Silent generator running in full emissions compliance.
Key Features
- OEM Sealing Integrity — Manufactured to the same compression and thread specification as the original, maintaining an airtight seal on the DEF tank to prevent fluid contamination or evaporation.
- Drop-In Replacement — Threads directly onto the DEF tank filler neck of Super-Silent series generators with no rework or adaptation needed.
- Super-Silent Series Fitment — Confirmed for Multiquip Super-Silent generator models; verify your model against part number EE61039 before ordering.
- Emissions System Protection — A properly sealing DEF tank cap keeps diesel exhaust fluid uncontaminated, supporting correct SCR system operation and Tier 4 emissions compliance.
- Regulatory Compliance — Maintaining an intact, OEM-spec DEF tank cap is essential for Tier 4 Final emissions conformance; a cracked or missing cap can trigger fault codes and take a generator offline.
The DEF tank cap seals the diesel exhaust fluid reservoir on Tier 4-compliant generators equipped with a selective catalytic reduction (SCR) emissions system. It prevents contamination, moisture ingress, and fluid loss — all of which can degrade DEF quality and cause the SCR system to underperform or trigger fault codes. A worn, cracked, or missing cap can result in unexpected shutdowns and failed emissions checks, making timely replacement a straightforward way to protect both machine uptime and regulatory compliance.
