• Precision Threading - Machined threads ensure secure, leak-proof connections that won't loosen over time
• Corrosion Resistant Finish - Factory applied coating protects against moisture, chemicals, and environmental degradation

Liquidtight Protection

• Weatherproof Seal - Creates watertight barrier preventing moisture ingress in wet locations
• Chemical Resistance - Protects against oils, coolants, and industrial chemicals commonly found in manufacturing environments
• Dust Protection - Sealed design prevents particulate contamination of electrical connections
• Temperature Stability - Maintains seal integrity across wide temperature ranges

Professional Installation Features

• Straight Configuration - Provides direct conduit connection without angular offset for streamlined installations
• Standard Trade Size - 1-1/4" sizing matches common FMC conduit dimensions for perfect fit
• Contractor-Friendly Design - Easy installation reduces labor time and ensures reliable connections
• NEC/CEC Compliant - Meets all applicable electrical codes for professional installations

Technical Specifications

This liquidtight connector features 1-1/4" trade size compatibility with flexible metal conduit (FMC) systems. The malleable iron construction provides superior strength compared to standard steel alternatives, while the non-insulated throat design maintains continuous equipment grounding. Rated for Class I, Division 2 hazardous locations, this connector meets NEC/CEC standards for professional electrical installations. Product dimensions measure 2.25" width x 2.25" height x 2.19" depth with a weight of 0.55 pounds, providing substantial construction in a compact profile.

Installation Process

1. Verify FMC conduit end is cut square and deburred to prevent seal damage
2. Thread connector onto conduit end, ensuring full engagement of threads
3. Apply appropriate thread sealant if required by local codes or environmental conditions
4. Insert connector assembly through enclosure knockout or hub opening
5. Secure with locknut from inside enclosure, tightening to manufacturer specifications
6. Verify liquidtight seal integrity and proper grounding continuity before energizing

Applications

Perfect for:

• Manufacturing Facilities - Machine tool connections, conveyor systems, and automated equipment
• Chemical Processing Plants - Pump stations, mixing equipment, and process control panels
• Food Processing - Washdown areas, packaging equipment, and refrigeration systems
• Outdoor Installations - Weather-exposed equipment connections and exterior control panels
• Marine Applications - Dock facilities, boat lifts, and waterfront electrical systems
• Agricultural Systems - Irrigation controls, grain handling equipment, and livestock facilities
• Municipal Infrastructure - Water treatment plants, sewage facilities, and public works installations
• HVAC Equipment - Rooftop units, cooling towers, and mechanical room connections

Liquidtight Connector System Benefits

Liquidtight connectors provide essential protection in environments where standard conduit fittings would allow moisture, dust, or chemical infiltration. The flexible metal conduit compatibility allows for equipment vibration absorption while maintaining secure electrical connections. This combination prevents premature equipment failure, reduces maintenance costs, and ensures reliable operation in challenging industrial environments where rigid conduit systems would be impractical.

Why Choose Malleable Iron Construction?

Malleable iron offers superior mechanical properties compared to standard steel or aluminum alternatives, providing exceptional impact resistance and thread durability. This material choice ensures long-term reliability in high-vibration applications and prevents thread stripping during installation or maintenance. Combined with Eaton Crouse-Hinds' century of electrical innovation, this connector delivers the professional-grade performance that electrical contractors trust for critical installations.
