Technical Specifications

This 3/4" trade size liquidtight connector features malleable iron construction with non-insulated throat design for optimal grounding continuity. The straight connector configuration accommodates flexible metal conduit (FMC) systems with secure threading and compression sealing. Product dimensions measure 1.75" length x 1.56" width x 1.56" height with a lightweight 0.29 lb construction. The connector is specifically rated for Class I, Division 2 hazardous locations and complies with NEC/CEC standards for professional electrical installations.

Installation Process

1. Verify proper 3/4" FMC conduit size and cut conduit to required length with appropriate cutting tools
2. Remove any burrs or sharp edges from conduit end to prevent damage to sealing components
3. Thread the compression nut onto the FMC conduit before inserting into connector body
4. Insert conduit fully into connector body ensuring proper seating against internal stop
5. Hand-tighten compression nut to finger-tight position, then use appropriate wrenches for final tightening
6. Verify liquidtight seal by checking for proper compression of sealing elements around conduit jacket

Applications

Perfect for:

• Hazardous Location Installations - Chemical processing plants, refineries, and manufacturing facilities
• Outdoor Electrical Systems - Weather-exposed conduit runs requiring moisture protection
• Industrial Motor Connections - Flexible connections to vibrating equipment and machinery
• Commercial HVAC Systems - Rooftop equipment connections subject to weather exposure
• Food Processing Facilities - Washdown areas requiring liquidtight sealing protection
• Marine Applications - Dock electrical systems and waterfront installations
• Agricultural Buildings - Barn and greenhouse electrical systems with moisture concerns
• Municipal Infrastructure - Water treatment plants and outdoor lighting systems

Liquidtight FMC System Benefits

Liquidtight flexible metal conduit systems provide superior protection compared to standard flexible conduit by combining mechanical strength with environmental sealing. The FMC construction offers excellent pull strength and crush resistance while the liquidtight jacket prevents moisture infiltration. This combination makes liquidtight FMC ideal for applications where both flexibility and weather protection are required, particularly in hazardous locations where ignition prevention is critical.

Why Choose Malleable Iron Construction?

Malleable iron offers significant advantages over standard steel construction, providing superior impact resistance and dimensional stability under stress. This material choice ensures the connector maintains its sealing integrity even under mechanical stress or temperature cycling. The non-insulated design maintains electrical continuity throughout the grounding system while the precision-machined threads guarantee reliable, long-term connections that won't loosen over time. Trusted by electrical professionals for over 100 years, Eaton Crouse-Hinds liquidtight connectors deliver the reliability and performance demanded in critical electrical installations.
