Empire 137B0150 Round U-bolt 1-1/2 Inch Pipe Steel

Product Description

The EMPIRE 137B0150 is a round steel U-bolt designed to secure pipe to structural supports in mechanical, plumbing, and HVAC piping systems. This fastener uses a 3/8-16 UNC thread with a 2-1/2 inch thread length and a 2-3/8 inch body length, sized to fit 1-1/2 inch pipe. The U-bolt ships without a mount plate and includes four hex nuts for immediate assembly. At 0.3 pounds, it is a lightweight but load-rated fastener with a published capacity of 1,220 pounds. The uncoated steel construction suits dry or protected indoor mechanical installations. Licensed plumbers, HVAC pipefitters, and mechanical contractors are the typical installers.

This U-bolt is used in residential and commercial piping installations where 1-1/2 inch pipe must be clamped to beam flanges, strut channel, or structural members without a welded or bolted mount plate. It is appropriate for gas, hydronic, refrigerant, and general mechanical piping support applications. The round shape conforms evenly to pipe OD, distributing load around the pipe circumference. A single unit is packaged per order, making it straightforward to specify exact quantities for multi-point hanger layouts.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters in accordance with IPC and IFGC pipe support spacing requirements. Power down or isolate the system before working on pressurized lines. Thread both hex nuts onto each leg hand-tight before final tightening to ensure even seating against the support structure. Do not overtighten on plastic-lined or coated pipe without a protective sleeve.
