K4115-10 - 3-Inch Hose Coupler for Fume Extraction

Extend Your Reach with the Lincoln K4115-10 Connector

When it comes to welding safety, positioning your fume extraction hood correctly is non-negotiable. However, shop layouts and large workpieces often present challenges that standard hose lengths cannot overcome. The Lincoln Electric K4115-10 Hose-To-Hose Connector is the perfect solution for welders and fabricators looking to extend the range of their fume extraction equipment. Designed to couple two 3-inch (76mm) hoses, this accessory provides the extra length needed to reach difficult spots without moving the entire extraction unit.

This connector is more than just a simple splice; it is engineered to maintain the airflow dynamics of your extraction system. In fume extraction, any drop in pressure or air leakage can compromise the capture velocity at the hood, allowing smoke and fumes to escape into the breathing zone. The K4115-10 offers a snug, secure fit that minimizes air loss, ensuring that your system continues to operate at peak efficiency even with the added hose length. It is an essential tool for shops that handle large structural fabrications, automotive repair, or shipbuilding where flexibility is key.

The 3-inch diameter is a standard size for many portable and stationary fume extractors, making this connector highly compatible with existing Lincoln Electric setups and potentially other systems utilizing standard 76mm ducting. Its robust design ensures it can handle the rough and tumble of a busy workshop, resisting crushing and impact damage. It is lightweight enough not to cause sagging in suspended hose runs, yet strong enough to hold connections secure during movement.

Using the K4115-10 is incredibly easy. Simply insert the connector into the ends of the two hoses you wish to join. For the most secure connection, especially in high-movement applications, users may opt to secure the hose ends over the connector with standard hose clamps (sold separately). This small investment in a quality connector can significantly improve shop safety and workflow efficiency, eliminating the frustration of short hoses and ensuring clean air is maintained throughout the facility.
