Overview

The NSI Industries TWB-53 is a 1-inch trade size insulating bushing designed for use with Electrical Metallic Tubing (EMT) systems. Constructed from durable polyethylene, this bushing provides a non-conductive barrier between metal conduit and cables, preventing abrasion and insulation damage during installation and operation. The TWB-53 features dimensions of 0.945" (A), 1.300" (B), and 0.635" (C), ensuring compatibility with standard 1-inch EMT fittings. Its polyethylene material offers excellent chemical resistance, UV stability, and a temperature tolerance range from -40°C to 85°C, making it suitable for both indoor and outdoor industrial applications. This bushing is specifically engineered for nonmetallic low-voltage cabling, including voice, video, and data cables, and can be used for single or multiple cable runs. Installation is straightforward: simply place the bushing over the end of Rigid Metal Tubing (RMT) and tap lightly onto the tubing. The TWB-53 eliminates the risk of ground faults and short circuits associated with metal bushings while ensuring smooth wire entry and exit from conduit runs. Ideal for manufacturing plants, commercial buildings, and utility installations, this cost-effective solution maintains system integrity and safety in electrical installations.
