Built to exacting engineering tolerances, this 4-inch brass U-bolt offers a nominal pipe capacity of 4 inches, with an inside width (A) of 4.75 inches and an inside length (B) of 4.05 inches. Constructed from high-grade brass (typically UNS C26000 or equivalent), it exhibits excellent resistance to a wide range of corrosive media, including saltwater, mild acids, and alkalis, making it ideal for marine, chemical processing, and plumbing systems. The 1/2"-13 UNC (Unified National Coarse) thread size ensures compatibility with standard hardware and provides ample strength for secure fastening. The U-bolt's precise dimensions guarantee a snug fit around standard 4-inch nominal pipe, preventing movement and vibration.
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 pipe, ensuring the pipe is seated within the curve of the U-bolt. 2. Place the accompanying washers and nuts onto the threaded ends of the U-bolt. 3. Tighten the nuts evenly and progressively, alternating sides, until the U-bolt securely engages the pipe and mounting surface without deforming the pipe. 4. Verify that the pipe is held firmly in place and does not exhibit excessive movement.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the nuts, which can deform the pipe or U-bolt. | Tighten nuts evenly and progressively, stopping when the U-bolt is snug and the pipe is secured, avoiding excessive force. |
| Using the wrong size U-bolt for the pipe diameter. | Confirm the pipe's nominal diameter and select a U-bolt with appropriate inside dimensions (width and length) for a secure fit. |
| Not using washers, leading to uneven pressure distribution and potential damage to the pipe or mounting surface. | Always use flat washers under the nuts to distribute the clamping force evenly. |
