The line of electric pipe bender conduit benders have been designed for performance and durability exceeding the expectations of today’s professional. It is recommended to familiarize yourself with bending concepts, techniques and learn the bender’s functionality to provide you a positive experience while greatly improving the overall outcome of your project.
Conduits come in two types, EMT and Rigid conduits and can be found in various sizes The electric pipe bender provides conduit benders for EMT in ½”, ¾”, 1” and 1-¼” conduit and ½”, ¾”, and 1” Rigid conduit.
To aid bending when performing a ground or air bend, the benders are marked with different alignment symbols to help the operator create the bends necessary to accomplish any project. The symbols found on the electric pipe bender benders are the arrow, the teardrop, the star point and angle markings. These markings are found on various sides of the bender head.
The four most common turns you need to know are 90 ° Stub-Up, Back to Back, Offset, and 3 Point Saddle. When fabricating certain tube profiles, combinations of bend markings are often used. Knowing the appropriate technique and method of making arches will allow you to implement most projects efficiently.

The spigot is bent by bending the duct into an L-shape or bending it at an angle of 90 °, placing the free end (short end) of the pipe to a specific length as shown in the diagram below. It is the most common arch and is part of other arcs. Typical applications for this arc include: routing the wire to electrical boxes, routing the wire up or down walls, routing the wire through the walls through floors and ceilings, and making bends in internal and external corners.
In some installations, it will be necessary to trim the unbent side of the wire to a different length as desired to fit the installation. Use a pipe cutter to ensure a smooth, precise cut and deburring to keep electrical wiring safe while broaching. The hacksaw can be replaced as long as the pipe cutting edge is properly prepared.
Back-to-back bending is another bend style that is needed when routing electrical wiring. In fact, the concept is formulated by the need to know the 90 ° distance from the trailing edge of the bend to a fixed point in the conduit in order to determine other bending operations to meet the installation requirements. As you will see, it rests on a 90 ° elbow, and when you do the most common use of this elbow, it will look like an elongated U.
Knowing this bending method will be needed if you want to fit a cable duct between two parallel surfaces, such as two walls or joists, while keeping the outer edges of the U-legs in contact with the two surfaces. This allows for proper anchoring and a nice, clean appearance.
