Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt of incorrect pipe size or thread specification.Always verify the pipe's outer diameter and the required thread size before selecting a U-bolt to ensure a proper fit and secure connection.
Insufficient or uneven tightening of the nuts.Tighten nuts symmetrically on both legs to distribute pressure evenly. Ensure the pipe is firmly held without crushing or deforming it.
Exposing brass to highly aggressive chemicals without verification.While brass offers good corrosion resistance, consult chemical compatibility charts for specific applications to confirm suitability.

Common Applications

  • Marine piping systems
  • Plumbing in coastal or humid environments
