Empire 137B0050 Round U-bolt 1/2 Inch Pipe Steel

Product Description

The EMPIRE 137B0050 is a round U-bolt designed to secure 1/2 inch pipe to structural supports in mechanical, plumbing, and HVAC piping systems. Manufactured from uncoated steel and conforming to multiple industry fastener standards, this U-bolt carries a rated load capacity of 485 pounds. The 1/4-20 UNC thread runs 2-3/8 inches in length, providing adequate engagement for standard hex nut fastening. The package includes four hex nuts, making it ready for immediate installation. This hardware is sized for 1/2 inch pipe and is sold individually. Plumbers, pipefitters, and HVAC technicians typically install this type of hanger during rough-in and support work on pipe runs.

This U-bolt is suited for use in residential and light commercial piping installations where 1/2 inch pipe must be anchored to hangers, strut channel, or structural members. The round bend profile cradles round pipe securely without mount plate hardware. Typical applications include domestic water supply lines, refrigerant copper piping supports, gas piping hangers, and other small-diameter pipe runs where a low-profile, threaded rod-style U-bolt is specified. The uncoated steel finish is appropriate for interior dry environments where corrosion protection is not required.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians as part of pipe support and hanger work. Shut off and isolate any pressurized piping system before disturbing existing supports. Ensure the U-bolt is properly seated around the pipe before tightening hex nuts evenly on both legs to maintain alignment. Consult applicable codes such as the IPC or IFGC for required pipe support spacing and hanger material requirements for specific pipe types and system pressures.
