Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, potentially deforming the pipe or stripping the threads.Use a torque wrench to tighten nuts to the manufacturer's recommended torque specification or a generally accepted value for the thread size and material.
Using the wrong size U-bolt for the pipe, leading to a loose fit or excessive stress.Always verify the nominal pipe size against the U-bolt's inside dimensions (width and length) before installation.

Common Applications

  • Marine plumbing and rigging
  • Chemical processing equipment support
  • Potable water systems
  • General pipe and conduit anchoring

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or environment to prevent galvanic corrosion.
  • Always use appropriate personal protective equipment during installation.
