KP5122-1 - Lincoln Viking PAPR Breathing Tube Assembly with FR Cover

Lincoln Electric KP5122-1 PAPR Hose Assembly Overview

The Lincoln Electric KP5122-1 PAPR Hose Assembly is a critical component designed to maintain the integrity and performance of VIKING Powered Air Purifying Respirator (PAPR) systems. Engineered to meet the rigorous demands of industrial environments, this assembly facilitates the safe transfer of purified air from the blower unit to the welding helmet headgear. The assembly features a robust, flexible breathing tube that measures 72 inches (6 feet) in length, providing operators with a generous range of motion necessary for complex welding positions and maneuvering around large workpieces.

A key technical feature of this assembly is the Twist & Lock connection mechanism. This design ensures a positive, airtight seal between the hose and the blower unit, preventing accidental disconnection during vigorous movement. The secure interface is essential for maintaining the assigned protection factor (APF) of the respirator system. Furthermore, the hose itself is constructed from lightweight, durable materials that resist kinking and crushing, ensuring consistent airflow delivery regardless of the welder's posture.

Included with the hose is a specialized Grey Flame-Retardant (FR) Protective Cover. In heavy fabrication and high-amperage welding applications, spatter and sparks pose a significant threat to rubber and plastic components. The FR cover acts as a sacrificial barrier, shielding the structural integrity of the breathing tube from thermal damage and abrasion. This addition not only enhances safety but also reduces the total cost of ownership by prolonging the service life of the hose. The cover is removable, allowing for inspection of the hose and cleaning as required by safety protocols.

This assembly is the direct OEM replacement for Lincoln VIKING PAPR systems, ensuring 100% compatibility and compliance with safety standards. It is an essential spare part for facilities prioritizing respiratory safety in welding, fabrication, and hazardous material handling sectors.
