Electrical Metallic Tubing (EMT) conduit is a popular choice for electrical wiring systems due to its cost-effectiveness, durability, and ease of installation. One essential skill when working with EMT conduits is bending them to meet the demands of your project. In this article, we will explore four different methods of bending EMT conduit to help you determine which technique is best suited for your needs.

1. Manual Bending with a Hand Bender:

The hand bender is a simple and cost-effective tool that comes in various sizes to accommodate different conduit diameters. To use it, first measure, mark and align the conduit with the bender’s markings. Then apply pressure on the handle while keeping the opposite end of the bender firmly in place. Gradually increase pressure until you achieve the desired bend angle.

2. Using a Mechanical Bender:

Mechanical benders are specially designed machines that can produce more accurate bends and cater to EMT conduits greater than 1-inch diameter. These devices come in various types, including tabletop, floor-standing, and even portable models. To operate a mechanical bender, mount or secure it properly, follow the manufacturer’s instructions for setting up the conduit, and then activate the bending mechanism.

3. Hydraulic Bending:

Hydraulic benders are ideal for large-scale projects requiring numerous and precise bends on thick diameter conduits. This is because hydraulic benders use hydraulic force to bend conduits smoothly and accurately. With a hydraulic bender, align the conduit with the machine’s markings or dies, engage the hydraulic pump, and watch as it effortlessly bends your EMT conduit to the desired angle.

4. Heat Bending:

It may be less common compared to other methods on this list but heat bending is still worth considering for specific situations where other options are impractical or inefficient. This method involves heating an EMT conduit slowly and evenly, usually with a propane torch, until it becomes malleable. Once the desired temperature is reached, use your hands or a bending tool to shape the conduit carefully, then let it cool and harden. Note that heat bending should be done cautiously to avoid damaging the conduit’s integrity or causing injury.

In conclusion, each of these four techniques for bending EMT conduit has its unique set of advantages and drawbacks. Factors such as project scale, conduit diameter, required precision, and available tools will ultimately determine which method is best suited for your specific needs. By mastering these techniques, you’ll be well equipped to tackle any challenges that may arise when working with EMT conduits.
