9SS31256-6 - Lincoln Electric Replacement Flexible Hose for LFA Arms - 6 Inch

Industrial Grade Replacement Ducting for Fume Extraction

The Lincoln Electric S31256-6 Flexible Duct is a critical maintenance component designed for the repair and upkeep of Lincoln LFA series fume extraction arms. In industrial welding environments, the integrity of the ventilation system is paramount for maintaining air quality standards and ensuring regulatory compliance. Over time, the flexible hose sections of extraction arms—specifically at the joints where articulation occurs—can succumb to wear, abrasion, and heat stress. This OEM replacement part ensures that your facility's air filtration systems continue to operate at peak efficiency without the pressure losses associated with cracked or leaking ducts.

Engineered to meet the rigorous demands of heavy manufacturing, this 6-inch diameter hose is constructed from a durable, flame-retardant polymer reinforced with a steel wire helix. This construction prevents the hose from collapsing under the high vacuum pressure generated by units such as the Mobiflex or Statiflex systems, while maintaining the flexibility required for the arm's positioning. The material is resistant to the hot sparks and abrasive particulate matter common in welding and grinding operations, extending the service life of the component and reducing maintenance intervals.

For MRO professionals and facility managers, utilizing genuine Lincoln Electric replacement parts guarantees compatibility and performance. The S31256-6 is designed to fit seamlessly with LFA 3.1 and LFA 4.1 extraction arms, minimizing downtime during repairs. Proper maintenance of these components is essential not only for equipment longevity but also for the protection of personnel and sensitive machinery from the accumulation of metallic dust and fumes. This product represents a direct, specification-grade solution for restoring the functionality of your existing environmental control assets.

Installation is straightforward, allowing maintenance teams to quickly swap out damaged sections and restore full suction capabilities. By maintaining a sealed and efficient vacuum path, this flexible duct helps optimize the energy efficiency of the extraction unit and ensures that hazardous particulates are effectively captured at the source.
