Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe.Always verify the nominal pipe size and ensure the U-bolt's inside dimensions are appropriate for a snug, secure fit.
Over-tightening the nuts, deforming the pipe or U-bolt.Tighten nuts incrementally and evenly on both sides. The goal is secure support, not to crush the pipe or threads.

Common Applications

  • Marine pipe support
  • Chemical processing systems
  • Plumbing and HVAC installations in corrosive environments
  • Decorative and architectural pipe mounting

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts and washers) with the 1/2"-13 thread size.
  • Brass is a relatively soft metal; avoid excessive force during installation that could strip threads or deform the bolt.
