Brass & Steel Flexible Arms: The Ultimate Protection for Your Wiring Systems

In today's industrial and commercial environments, protecting electrical wiring from damage is more critical than ever. Brass and steel flexible arms have emerged as the premier solution for safeguarding cables against moisture, corrosion, and physical stress. These flexible metal conduit arms combine durability with adaptability, making them indispensable across numerous industries.

This in-depth guide will walk you through everything you need to know about these versatile components, from their unique advantages to their diverse applications.

Understanding Flexible Conduit Arms: More Than Just Protection

What Makes Them Special?

Unlike rigid conduits, brass flexible conduit and steel flexible conduit offer:

• 360° flexibility for easy installation in complex routing scenarios
• Superior durability that withstands extreme temperatures and harsh conditions
• Built-in strain relief to prevent cable damage from vibration and movement

Material Matters: Brass vs. Steel

1. Brass Armored Cable Conduit
   • Excellent corrosion resistance, especially in marine environments
   • Natural EMI/RFI shielding properties
   • Ideal for food processing and chemical applications
2. Stainless Steel Flexible Tubing
   • Unmatched strength for heavy-duty applications
   • Superior resistance to high temperatures and abrasion
   • Perfect for oil & gas, mining, and industrial automation

• ATEX certification for explosive atmospheres

4. Installation Factors

• Compatibility with existing EMT flexible conduit arm systems
• Ease of cutting and termination
• Availability of specialized fittings

Installation Best Practices for Optimal Performance

Step-by-Step Guide

1. Planning Your Route
   • Map out the path to minimize bends
   • Allow extra length for movement in dynamic applications
2. Proper Cutting Techniques
   • Use a rotary cutter for clean edges on stainless steel flexible tubing
   • Deburr all cut ends to prevent cable damage
3. Secure Connections
   • Use appropriate fittings for your brass flexible conduit or steel variant
   • Apply thread sealant for liquid-tight connections
4. Strain Relief Implementation
   • Install clamps within 12 inches of termination points
   • Use specialized flexible metal conduit arm connectors for moving parts
5. Final Inspection
   • Check for proper grounding continuity
   • Verify all connections are secure

Maintenance Tips for Long-Term Reliability

Routine Checks

• Inspect for signs of corrosion, especially in brass armored cable conduit
• Check for abrasion at contact points
• Verify waterproof seals remain intact

Troubleshooting Common Issues

Problem: Conduit becoming stiff
Solution: Replace sections exposed to extreme temperatures

Problem: Moisture inside conduit
Solution: Upgrade to waterproof flexible conduit with better seals

Problem: Fittings coming loose
Solution: Use thread-locking compounds on vibration-prone connections
