K2389-8 - Lincoln Electric Miniflex Extraction Hose 16ft K2389-8

Reliable Fume Extraction for Professional Fabrication

The Lincoln Electric K2389-8 Extraction Hose is a critical component for maintaining a safe and compliant welding environment. Designed specifically for use with the Lincoln Electric Miniflex® portable fume extraction system, this hose ensures that hazardous particulate matter and fumes are effectively transported from the source to the filtration unit. With a length of 16 feet (5 meters), it provides welders with the necessary range of motion to work around large assemblies without compromising the efficiency of the vacuum system.

Constructed from high-quality, high-temperature materials, the K2389-8 is built to withstand the thermal stresses common in welding operations. Unlike standard vacuum hoses which may soften or collapse under heat and negative pressure, this hose features a robust spring steel reinforcement. This internal structure maintains the hose's cylindrical shape, ensuring consistent airflow and static pressure even when the hose is bent around corners or draped over equipment. The 1-3/4 inch (45mm) diameter is engineered to match the airflow characteristics of the Miniflex turbine, optimizing suction velocity for effective source capture.

Integration is seamless thanks to the inclusion of hose-to-tube adapters on both ends of the assembly. These adapters are sized at 1-3/4 inches (45mm) to fit perfectly into the inlet of the Miniflex base unit and connect securely to the outlet of compatible nozzles, such as the EN-20 and EN-40 models. This secure fitment minimizes air leaks, which is vital for maintaining the system's overall efficiency. For users requiring longer reach, this hose can be used in conjunction with other extensions, although Lincoln Electric recommends maintaining a maximum total hose length of 24 feet (7.5 meters) when used with the Miniflex to ensure optimal performance levels are retained.

Whether you are replacing a worn hose or extending your current setup, the K2389-8 offers the durability and compatibility required for professional industrial applications. It is an essential accessory for automotive repair, general fabrication, and maintenance operations where source capture of welding fumes is a priority.
