  • Corrosion-Resistant Finish - Professional-grade coating withstands harsh environmental conditions and chemical exposure

Liquidtight Sealing Performance

  • Weatherproof Protection - Creates reliable barrier against moisture, dust, and contaminants in wet location installations
  • Compression Sealing - Advanced sealing mechanism provides consistent liquidtight performance across temperature variations
  • Chemical Resistance - Engineered materials resist degradation from oils, solvents, and industrial chemicals

Hazardous Location Compliance

  • Class I, Division 2 Rating - Certified for use in locations where flammable gases or vapors may be present under abnormal conditions
  • NEC/CEC Compliant - Meets all applicable electrical code requirements for hazardous location installations
  • Professional Certification - Rigorous testing ensures reliable performance in critical safety applications

Technical Specifications

This 1/2" trade size liquidtight connector features malleable iron construction with insulated throat design for FMC applications. The straight configuration measures 1.75" in length, 1.25" in width and height, with a compact 0.18 lb weight for easy installation. Engineered for Class I, Division 2 hazardous locations with full NEC/CEC compliance, this connector provides reliable liquidtight sealing while maintaining electrical continuity through the malleable iron body.

Installation Process

  1. Strip flexible metal conduit to appropriate length, ensuring clean, square cut
  2. Insert FMC into connector body until conduit seats properly against internal stop
  3. Thread connector onto enclosure or junction box hub hand-tight
  4. Tighten connector using appropriate wrench, ensuring proper compression seal
  5. Verify liquidtight seal integrity and electrical continuity
  6. Complete installation per NEC/CEC requirements for hazardous locations

Applications

Perfect for:

  • Petrochemical Facilities - Refineries, chemical processing plants, and fuel storage areas
  • Manufacturing Plants - Industrial facilities with potential vapor or gas exposure
  • Paint Spray Booths - Automotive and industrial coating operations
  • Grain Handling Facilities - Agricultural processing and storage installations
  • Pharmaceutical Manufacturing - Clean room and controlled environment applications
  • Food Processing Plants - Wet location installations requiring frequent washdown
  • Marine Applications - Shipboard and offshore platform electrical systems
  • Underground Installations - Subway systems, tunnels, and below-grade facilities

Liquidtight Connector System Benefits

Liquidtight connectors provide superior environmental protection compared to standard conduit fittings, making them essential for installations exposed to moisture, chemicals, or contaminants. The flexible metal conduit compatibility allows for equipment vibration isolation while maintaining excellent grounding continuity. This combination of flexibility and protection makes liquidtight systems ideal for motor connections, outdoor installations, and any application where standard rigid conduit cannot accommodate movement or environmental exposure.

Why Choose Malleable Iron Construction?

Malleable iron offers significant advantages over standard steel in demanding electrical applications. The superior strength and ductility prevent cracking under impact or thermal stress, while the material's excellent machinability ensures precise threading and superior sealing surfaces. Combined with Eaton Crouse-Hinds' century of manufacturing expertise, this malleable iron liquidtight connector delivers the reliability and longevity that electrical professionals demand for critical hazardous location installations.

Crouse-Hinds LTB50 – Frequently Asked Questions

1) What applications use Crouse-Hinds Series Liquidator liquidtight connectors?
These straight liquidtight connectors secure flexible metal conduit in wet locations. Common uses include outdoor equipment connections, food processing facilities, chemical plants, and washdown areas. The liquidtight seal prevents moisture and contaminants from entering junction boxes.
2) What conduit sizes are compatible with 1/2 inch liquidtight connectors?
This connector fits 1/2 inch flexible metal conduit (FMC). Verify exact conduit outer diameter before installation. The connector grips the conduit securely while maintaining liquidtight integrity through compression sealing.
3) How do you install liquidtight flexible metal conduit connectors?
Thread the connector onto the conduit end and tighten the compression nut. Insert the threaded end through the knockout and secure with the locknut from inside the enclosure. Tighten both compression nut and locknut to achieve proper seal and mechanical connection.
4) What finish protects malleable iron liquidtight connectors?
Crouse-Hinds applies corrosion-resistant finishes to malleable iron bodies. Standard finishes include zinc plating or electrogalvanized coatings. Some models feature additional protective coatings for harsh chemical environments. Check specific product markings for finish type.
5) What electrical ratings apply to Series Liquidator connectors?
These connectors typically handle standard building voltages up to 600V. Current capacity depends on wire fill and conduit size. The malleable iron construction provides excellent grounding continuity when properly installed with locknut tightened.
6) Do liquidtight connectors meet NEC requirements?
UL-listed Crouse-Hinds liquidtight connectors comply with NEC Article 350 for flexible metal conduit installations. They provide required liquidtight seal and grounding path. Verify local code requirements for specific applications and environmental conditions.
7) What accessories work with liquidtight FMC systems?
Compatible accessories include 90-degree connectors, cable pulling lubricant, and grounding bushings. Flexible conduit systems often require expansion fittings for temperature changes. Consider strain relief boots for high-vibration applications.
8) How tight should compression nuts be on liquidtight connectors?
Tighten compression nuts hand-tight plus 1/4 to 1/2 turn with wrenches. Over-tightening can damage sealing surfaces or distort the conduit. Under-tightening allows moisture penetration. The connection should feel secure without excessive force.
9) How do you maintain liquidtight connector seals?
Inspect sealing surfaces annually for cracks or deterioration. Re-tighten compression fittings if loosening occurs. Replace connectors showing seal damage or thread wear. Clean debris from threads before reassembly to maintain proper sealing compression.
10) What other Crouse-Hinds liquidtight connectors are available?
The Series Liquidator line includes 90-degree connectors, different sizes from 3/8 to 4 inches, and specialty fittings. Crouse-Hinds also makes non-metallic and explosion-proof liquidtight connectors for specific applications.
11) What field conditions affect liquidtight connector performance?
Temperature cycling can loosen compression fittings over time. Chemical exposure may degrade sealing materials. Vibration requires periodic inspection and retightening. UV exposure affects some seal compounds in outdoor installations.
12) What are the key measurements for 1/2 inch liquidtight connectors?
Standard 1/2 inch connectors use 3/4 inch-14 NPT threads for enclosure connection. Overall length varies by manufacturer but typically ranges 2-3 inches. Hex size for locknut installation is usually 1 inch. Verify specific dimensions against knockout and space requirements.
