TSI INOX Conduits presents our premium Stainless Steel REA Explosion-Proof Reducing Adapter, a critical component for adapting conduit and equipment openings in hazardous area installations. Manufactured from premium SS316 (CF8M) stainless steel and featuring a vibration polished finish, our REA adapters provide secure, corrosion-resistant connections when reducing conduit hubs to a smaller size or enlarging drilled and tapped openings by one NPT size.
The REA (Explosion-Proof Reducing Adapter) is specifically designed for use in NEC/CEC Class I, II, and III hazardous locations to adapt rigid conduit, IMC, and equipment openings to different trade sizes while maintaining explosion-proof integrity. Whether you are reducing conduit sizes to connect to smaller equipment hubs, adapting to field modifications, or completing installation in petrochemical refineries, chemical processing plants, offshore platforms, or food processing facilities, TSI's stainless steel REA adapters deliver the quality, durability, and code compliance your project demands.
TSI REA adapters meet or exceed the following hazardous location standards:
