Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this 3" Nylon U-Bolt features an inside width (A) of 1.34 inches and an inside length (B) of 2.87 inches, accommodating standard 3-inch nominal pipe. The U-bolt is manufactured from high-strength nylon, providing excellent resistance to chemicals, moisture, and UV degradation, making it ideal for marine, chemical processing, and outdoor installations. The 1/2"-13 UNC thread size on the legs ensures compatibility with standard nuts and washers (sold separately), facilitating secure clamping. Its non-conductive nature also makes it suitable for applications where electrical isolation is critical.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using undersized or oversized U-boltsAlways verify the pipe's nominal size and measure the U-bolt's inside dimensions (A and B) to ensure a proper fit for optimal support and strain distribution.
Overtightening the nutsTighten nuts to the manufacturer's recommended torque specification or until snug, to prevent stress cracking or deformation of the nylon material.

Common Applications

  • Pipe Support in Corrosive Environments
  • Electrical Conduit Mounting
  • Marine and Offshore Installations

⚠️ Engineering Warnings

  • Maximum load capacity of nylon U-bolts may be lower than metallic equivalents; consult product load charts.
  • Ensure compatibility with specific chemical exposure if not a standard industrial application.
