Overview

The ABB H400CAPA 4-inch aluminum capoff is a precision-engineered termination accessory for rigid and intermediate metal conduit (IMC) systems. Constructed from durable aluminum, this capoff provides a secure, weather-resistant seal for conduit ends while maintaining electrical safety and system integrity. The integrated thermoplastic insulating throat ensures proper insulation and prevents moisture ingress, while the nitrile (BUNA-N) sealing ring delivers reliable environmental protection against dust, water, and contaminants. Designed for compatibility with standard 4-inch rigid and IMC conduit, the H400CAPA is ideal for industrial, commercial, and utility applications where conduit termination integrity is critical. The compact design allows for easy installation in tight spaces, and the corrosion-resistant aluminum construction ensures long-term performance in demanding environments. Compatible with ABB’s H400 series and other industry-standard conduit systems, this capoff meets or exceeds NEC and UL requirements for conduit termination safety. Use the H400CAPA to maintain system compliance, reduce installation time, and ensure reliable conduit sealing in both indoor and outdoor applications.
