Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening brass fittings, which can lead to thread stripping or material deformation.Apply consistent, firm pressure. Consult torque specifications if available, or tighten until the pipe is securely held without excessive force.
Using the wrong size U-bolt for the pipe, resulting in a loose or overly constricted fit.Verify the pipe's nominal size and confirm the U-bolt's inside width (A) is appropriate for a secure, non-damaging grip.

Common Applications

  • Marine pipe and conduit support
  • Plumbing and sanitary systems
  • Industrial pipe anchoring

⚠️ Engineering Warnings

  • Ensure compatibility with surrounding materials to prevent galvanic corrosion if used with dissimilar metals.
  • Do not exceed the recommended load capacity for the U-bolt and mounting hardware.
