Overview

The Woodhead MAX-LOC®/Watertite® Cord Grip (SKU 5638NM) is a non-metallic, liquid-tight cord grip designed for secure cable entry in industrial environments. This straight male cord grip features a 1" NPT threaded hub, providing a firm connection to enclosures, junction boxes, and control panels. It is engineered for Form Size F4 and accommodates cable diameters from 19.05mm to 22.23mm (0.750" to 0.875"), ensuring a precise fit for flexible cords. Constructed from durable nylon, the body offers exceptional resistance to impact and corrosion, making it ideal for harsh chemical or abrasive conditions. The integrated rubber grommet creates a liquid-tight seal, preventing moisture, dust, and contaminants from entering while reducing cord pull-out. This seal is formulated to withstand a wide temperature range and resist common industrial chemicals, ensuring long-term performance. The MAX-LOC®/Watertite® series is renowned for its strain relief capabilities, preventing cable and conductor damage from excessive pulling or bending. This is critical in applications subject to vibration or frequent cable manipulation. The non-metallic construction is advantageous in environments where electrical conductivity is a concern or weight reduction is beneficial. Key features include: Rugged construction for boxes, cabinets, push-button stations, and general-purpose enclosures; corrosion and impact resistance via nylon body; liquid-tight seal with rubber grommet; strain relief to minimize cord pull-out; and a 1" NPT thread for standardized integration. This cord grip is rated for Type 3R (Max-Loc without O-ring) and Type 6P (with O-ring/locknut), offering versatile protection levels. Applications span manufacturing, automation, food and beverage processing, and any industry requiring robust protection for electrical connections in wet or dusty environments.
