Installation Procedure

1. Position the U-bolt around the 4" pipe, ensuring it straddles the pipe correctly. 2. Thread the nuts onto the U-bolt legs until snug against the mounting surface. 3. Tighten the nuts alternately and evenly to achieve the required clamping force, but avoid overtightening which could deform the pipe.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always verify the nominal pipe size against the U-bolt's inside width and length specifications before installation.
Overtightening the U-bolt nuts, leading to pipe deformation or damage.Tighten nuts gradually and evenly, using a torque wrench if specified, to apply the correct clamping force without stressing the pipe.
Installing in an environment exceeding the material's chemical resistance.Confirm the brass material is suitable for the specific chemicals and environmental conditions present in the application.
