Empire 137B0800 Round U-bolt 8 Inch Pipe 5/8-11 Unc Steel

Product Description

The EMPIRE 137B0800 is a round U-bolt designed to support and secure 8-inch pipe in mechanical, plumbing, and industrial piping systems. Manufactured from uncoated steel, this U-bolt carries a rated load capacity of 3,620 pounds, making it suitable for heavy-duty pipe support applications. The fastener uses a 5/8-11 UNC thread standard with a thread length of 7-1/8 inches and an overall width of 9-3/8 inches. It ships without a mount plate and includes four hex nuts. Licensed pipefitters, plumbers, and mechanical contractors install this hardware as part of pipe hanger and support assemblies.

The 137B0800 is used in commercial and industrial piping installations where 8-inch pipe must be suspended, braced, or restrained. Typical applications include HVAC hydronic systems, process piping, fire protection headers, and utility mechanical rooms. The uncoated steel construction is common in interior dry locations where additional corrosion protection is not required. The included hex nuts allow for direct installation without sourcing additional hardware, streamlining the assembly process on the job site.

Compatibility

Designed as an OEM-style pipe support component for 8-inch nominal pipe size (NPS) applications in mechanical and plumbing piping systems. Conforms to fastener standards A-A-1192 A Type 24, MSS-SP-58, SP-69 Type 24, and WW-H-171-E Type 24.

Installation Notes

Installation is typically performed by licensed pipefitters or plumbers working under applicable mechanical codes such as the International Plumbing Code or ASME B31 piping standards. Ensure the supporting structure is rated for the combined load of the pipe, fluid, and insulation before fastening. Verify thread engagement is sufficient and torque nuts evenly to prevent lateral shifting of the pipe. Do not use this U-bolt without mount plate in applications requiring a backing plate for structural attachment.
