Designed for demanding industrial environments, this 4" nominal pipe size brass U-bolt features an inside width (A) of 3.49 inches and an inside length (B) of 3.49 inches, accommodating standard pipe diameters. Manufactured from high-quality brass (typically UNS C36000 free-machining brass), it offers exceptional resistance to corrosion, particularly in marine, chemical processing, and wastewater applications where galvanic corrosion is a concern. The 1/2"-13 UNC thread size provides robust clamping force, ensuring secure mounting to a variety of structural elements. This U-bolt is ideal for applications requiring non-sparking properties and excellent durability against saltwater and aggressive chemicals.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Position the U-bolt around the 4" nominal pipe, ensuring the pipe is properly seated within the U-bolt's curve. 2. Place the included backing plate (if applicable) and thread the nuts onto the U-bolt legs. 3. Tighten the nuts evenly and progressively to achieve the required clamping force, ensuring the pipe remains securely fastened without deformation.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect thread size for the application's load requirements. | Verify the 1/2"-13 thread size is adequate for the anticipated static and dynamic loads. Consult load charts if necessary. |
| Over-tightening the nuts, leading to pipe deformation or U-bolt fatigue. | Tighten nuts to the manufacturer's recommended torque specification or until a firm, secure hold is achieved without visible distortion of the pipe or U-bolt. |
| Installing in an environment where brass is susceptible to dezincification or stress corrosion cracking. | While brass offers good corrosion resistance, understand its limitations. For extremely aggressive chemical or high-stress environments, consider stainless steel or other alloys. |
