Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the U-bolt, which can deform the pipe or mounting surface.Tighten nuts until snug and the pipe is secure, avoiding excessive force. Use a torque wrench if specific torque values are required.
Using the wrong size U-bolt for the pipe, leading to a loose or damaged installation.Always verify the pipe's nominal diameter and select a U-bolt with matching inside dimensions.

Common Applications
