Technical Specifications

This REA series adapter features male 3/4" NPT input connection transitioning to female 1" NPT output connection, specifically designed for rigid and IMC conduit systems. The steel construction provides Class I, Division 1 hazardous location rating with full NEC/CEC compliance. Physical dimensions include 1.95 inches in height, 1.44 inches in both length and width, with a total weight of 0.27 pounds for easy handling and installation.

Installation Process

1. Verify conduit system is de-energized and properly locked out/tagged out
2. Apply appropriate thread sealant to male 3/4" NPT threads of incoming conduit
3. Thread adapter onto 3/4" conduit connection, tightening to manufacturer specifications
4. Apply thread sealant to male threads of 1" conduit or fitting
5. Thread 1" conduit into female end of adapter, ensuring proper engagement
6. Verify all connections are tight and properly sealed for hazardous location integrity

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
• Oil and Gas Operations - Drilling platforms, pumping stations, and distribution facilities
• Manufacturing Plants - Paint booths, solvent handling areas, and chemical processing zones
• Grain Handling Facilities - Elevators, mills, and storage facilities with combustible dust hazards
• Pharmaceutical Manufacturing - Clean rooms and processing areas with flammable solvents
• Aviation Facilities - Hangars, fuel handling areas, and maintenance facilities
• Marine Applications - Ship electrical systems and offshore platform installations
• Mining Operations - Underground installations and surface processing facilities

Rigid/IMC Conduit System Benefits

Rigid and IMC conduit systems provide superior mechanical protection and grounding continuity compared to flexible conduit options. The threaded connections create permanent, vibration-resistant joints that maintain electrical continuity and explosion-proof integrity. This adapter enables seamless integration of different conduit sizes within the same system, allowing for optimized wire fill ratios and efficient routing in complex industrial installations.

Why Choose Steel Construction for Hazardous Locations?

Steel construction provides the mechanical strength and thermal properties essential for explosion-proof applications. Unlike aluminum or plastic alternatives, steel maintains dimensional stability under extreme temperature variations and provides superior impact resistance. The material's ability to dissipate heat rapidly helps prevent dangerous temperature buildup, while its robust construction ensures long-term reliability in the most demanding industrial environments where safety cannot be compromised.
