Overview

The ABB PKFSSS21/BL/25M is a precision-engineered flexible conduit designed for industrial automation, robotics, and machinery applications requiring high durability and flexibility. Constructed from a polyketone core reinforced with a stainless steel overbraid, this conduit delivers exceptional resistance to abrasion, chemicals, and extreme temperatures, ensuring long-term performance in demanding environments. The 21mm nominal conduit size (17mm NW size) with a fine pitch ensures smooth cable routing and optimal protection in tight spaces, while the 21.2mm outside diameter and 16.6mm inside diameter accommodate standard cable bundles without compromising structural integrity. The 25-meter reel length provides efficient material management for large-scale installations, reducing waste and streamlining logistics. With a static bend radius of 60mm, the conduit enables easy maneuverability around obstacles, maintaining cable protection during installation and operation. This conduit is engineered for reliability in harsh conditions, including exposure to oils, UV radiation, and mechanical stress, making it ideal for cable management in automated production lines, robotic arms, motion control systems, and other dynamic industrial applications where consistent performance under varying loads and movements is critical. The stainless steel overbraid enhances tensile strength and electromagnetic shielding, further supporting its use in sensitive electronic environments.
