Multiquip EE49411 Nipple 1/2" NPT x 4" LG Steel Black

The Multiquip EE49411 is a genuine OEM Nipple 1/2" NPT x 4" LG Steel Black designed for SG1400C3-55748, SG1400C4F, and SG1600C4F studio and diesel-powered generator models. As a factory-sourced component, it meets the original material and dimensional standards set for these units, ensuring a correct, leak-free connection in the fuel or fluid line where it is installed. Confirm your model code against the fitment list before ordering to ensure EE49411 is the right nipple for your application.

Key Features

• Steel Construction with Black Finish — Solid black steel build resists corrosion and handles the pressure demands of generator fuel and fluid systems without degradation.
• 1/2" NPT Threading for Secure Line Connection — Standard NPT thread form seals reliably when mated to compatible fittings, eliminating the risk of thread mismatch that leads to leaks.
• 4" Length for Correct Reach — The specified 4-inch length ensures the nipple spans the intended gap between connection points without requiring spacers or improvised extensions.
• Genuine OEM Part — Sourced directly from Multiquip, EE49411 matches the original specification for studio and diesel-powered generator plumbing systems, replacing the worn or damaged nipple with an exact-spec component.
• Confirmed Fitment for SG Series Generators — Verified for SG1400C3-55748, SG1400C4F, and SG1600C4F generator models, covering both studio and Tier 4 diesel-powered variants in this product family.
• Fuel System Integrity — A properly installed nipple of the correct length and thread spec keeps fluid routing sealed and aligned, preventing fuel or coolant leaks that would take a generator offline.

A pipe nipple is a short length of threaded pipe used to connect two fittings, valves, or components within a fluid line. In generator applications, nipples like the part are commonly found in fuel supply lines, coolant circuits, or auxiliary plumbing runs where a rigid, threaded connection is required. When a nipple corrodes, cracks, or develops thread damage, the resulting leak can disrupt fuel delivery or fluid circulation, causing the generator to run poorly or shut down entirely. Replacing a damaged nipple promptly with the correct OEM part restores system integrity and prevents further damage downstream.
