Professional Installation Advantages

• 4-Inch Trade Size - Compatible with large conduit runs in industrial electrical systems
• Standard Threading - Direct connection to rigid steel and IMC conduit without adapters
• Compact Profile - Recessed design minimizes space requirements in crowded installations
• Permanent Solution - Eliminates need for temporary sealing methods during construction

Technical Specifications

This conduit plug features a 4-inch trade size with standard rigid/IMC threading for direct connection to conduit systems. The gray iron alloy construction provides superior mechanical strength compared to standard steel alternatives. Product dimensions are 4.5 inches in height and length with a 1.22-inch width profile. The recessed design allows for flush mounting applications where space is limited. The plug weighs 3.8 pounds, reflecting its heavy-duty construction quality. Class I, Division 1 hazardous location rating ensures compliance with NEC and CEC requirements for classified area installations.

Installation Process

1. Verify conduit system is properly grounded and de-energized before installation
2. Clean conduit threads thoroughly to ensure proper sealing surface
3. Apply appropriate thread sealant rated for hazardous location use
4. Thread plug into conduit end, tightening to manufacturer specifications
5. Verify recessed installation provides adequate clearance for surrounding equipment
6. Complete hazardous location documentation and inspection requirements

Applications

Perfect for:

• Petrochemical Facilities - Refineries, chemical processing plants, and storage terminals
• Oil and Gas Operations - Drilling platforms, pumping stations, and pipeline facilities
• Manufacturing Plants - Paint booths, solvent handling areas, and chemical processing zones
• Grain Handling Facilities - Elevators, mills, and storage facilities with combustible dust
• Aircraft Hangars - Fuel handling areas and maintenance facilities
• Marine Applications - Ship electrical systems and offshore platform installations
• Pharmaceutical Manufacturing - Clean rooms and solvent processing areas
• Wastewater Treatment - Methane gas handling and processing equipment areas

Conduit Plug System Benefits

Conduit plugs provide essential safety functions in hazardous location electrical systems by permanently sealing unused conduit openings and preventing gas migration through conduit runs. Unlike temporary sealing methods, these permanent plugs ensure long-term compliance with safety codes while maintaining system integrity. The recessed design offers space-saving advantages in crowded electrical installations where every inch of clearance matters for maintenance access and equipment placement.

Why Choose Gray Iron Alloy Construction?

Gray iron alloy delivers superior mechanical properties compared to standard materials, providing exceptional strength and dimensional stability under extreme conditions. This material choice ensures the plug maintains its sealing integrity even when subjected to vibration, temperature cycling, and chemical exposure common in industrial hazardous locations. The Crouse-Hinds heritage of over 100 years in electrical safety solutions guarantees this plug meets the demanding requirements of professional electrical contractors working in the most challenging environments.
