K4114-25 - Lincoln Electric 3-Inch Fume Extraction Hose, 25 ft

Technical Overview of the Lincoln Electric K4114-25 Extraction Hose

The Lincoln Electric K4114-25 is a specialized extraction hose designed to facilitate the efficient removal of welding fumes and particulate matter from the work environment. Engineered with a 3-inch (76mm) inner diameter, this hose is optimized to handle significant airflow volumes required for effective fume capture. The 25-foot (7.6m) length provides operators with extended flexibility, allowing the extraction unit to be positioned at a safe distance while the capture nozzle is maneuvered directly to the source of the weld fumes.

Material construction is a critical aspect of the K4114-25. It is manufactured from a flexible, high-temperature resistant material capable of withstanding the thermal byproducts associated with welding processes. To ensure operational reliability, the hose features an integrated spring steel reinforcement helix. This structural addition serves a dual purpose: it maintains the hose's cylindrical shape to prevent collapsing under the negative pressure (vacuum) generated by the extraction unit, and it provides mechanical resilience against kinking and crushing in rugged industrial environments.

This hose is an essential accessory for maintaining air quality standards in fabrication shops. Its design balances flexibility with durability, ensuring that airflow remains unrestricted even when the hose is routed around obstacles or equipment. The K4114-25 is compatible with specific Lincoln Electric fume extraction systems that utilize a 3-inch intake or connection port, making it a vital component for facility maintenance and safety compliance.

Key Technical Specifications

The hose is defined by its robust build quality and specific dimensions tailored for industrial extraction. The 3-inch ID is a standard size for medium-to-heavy duty extraction requirements, balancing velocity and volume. The spring steel wire is embedded within the hose wall, protecting it from external abrasion while providing the necessary hoop strength. This design ensures that the hose retains its flexibility over time, resisting fatigue from constant bending and repositioning.
