K3969-1 - Lincoln Electric X-Tractor 5A/8A Fume Extraction Connection Kit

Comprehensive Connection Solution for X-Tractor Systems

The Lincoln Electric K3969-1 Connection Kit is an essential accessory designed to maximize the utility of X-Tractor 5A and X-Tractor 8A fume extraction units. In industrial environments where air quality and safety compliance are paramount, the ability to effectively distribute vacuum pressure across multiple extraction points is critical. This kit serves as the primary interface between the high-vacuum power source and the end-user attachments, such as extraction nozzles or fume guns. By utilizing this connection kit, facility managers and maintenance teams can configure their extraction systems to support complex workflows and multiple welding stations simultaneously.

Technical Configuration and Components

At the heart of the K3969-1 kit is the VV-50 valve, a robust main distribution valve engineered for versatility. The valve features a three-outlet design: two outlets with an outside diameter of 50 mm (2 inches) and one larger outlet with an outside diameter of 76 mm (3 inches). This configuration allows for significant flexibility in ducting and hose routing. The kit is comprehensive, including not just the valves but also the necessary structural components to ensure a leak-free system. It comes with two VV-50 valves (M17321-8), two 3-inch sleeves (S26767-41), a 4-inch sleeve (S26767-42), and a 4-inch to 3-inch steel reducer (S26767-31). These components ensure that the kit can adapt to various piping requirements found in diverse industrial settings.

Seamless Hose Integration

One of the primary challenges in setting up fume extraction systems is matching hose diameters to machine outlets. The K3969-1 addresses this with the inclusion of four S20591-8 Hose to Tube adapters. These adapters are specifically designed to bridge the gap between 1-3/4 inch (45 mm) I.D. hoses and the 50 mm (2 inch) outlets of the VV-50 valves. This ensures a tight, efficient seal that maintains the static pressure required for effective fume capture. Whether you are setting up a new fabrication cell or upgrading an existing X-Tractor unit, this kit provides the OEM-specified hardware to ensure reliable performance and compatibility with Lincoln Electric's ecosystem of fume extraction products.
