Copper Tube Bender | How to Bend Copper Pipe

Despite the availability of a broad choice of plumbing pipes and copper tubing, many people prefer the durability of conventional copper pipes.

Copper pipes may be purchased in rolls for use of walls, but put the pipes on the surface of the wall, in which case you will need to bend your pipes.

Depending on the method used, copper pipes can be bent with or without the use of specialized plumbing gear.

Here are some tips for bending copper pipe.


Applications for copper pipes

Copper pipes are commonly used as water supply pipes in the home. Because of their ornamental features, these pipes are frequently employed as crafting materials.

Although copper is flexible and simple to work with, it is not soft enough to bend precisely on its own.

Bending copper pipes without the proper equipment can cause pipe collapse, which means the pipe may create uneven edges rather than a smooth curve at the intended bend point.

This can damage the aesthetic appearance of handicrafts and obstruct water flow in plumbing.

How to Use a Tube Bender to Bend Copper Pipe

A manual tube bender is a compact, low-cost instrument that bends copper and other soft metals to a certain radius.

Manual tube benders are commonly seen in dual tube benders. The copper pipe can be put down at the center of the dual tube bender.

A gauge specifies the bend angle, which ranges from 0 to 90 degrees.

The tube bender’s upper piece (called a shoe) goes along the bend, ensuring a smooth and flawless curvature.


  • Bending that is precise and smooth
  • Simple to use
  • There is no need to heat the pipes.


  • Each pipe size causes a different bender.
  • Expensive
  • Bending copper pipe without a tube bender

Bending Copper Pipe Tips

Pipe Support: It is critical to support the copper pipe over the entire length of its bend to achieve a constant form. Support might be located either within or outside of the pipe.

Bend slowly: Even if the copper pipe is securely supported, bending it fast may cause it to pinch. If you gain the shape, ripples may form on the inside of the curve. Always bend gradually.

Shape the Bend: The easiest way to bend copper tubing to a 4- to 8-inch radius is to bend it over a cushioned knee. However, other curved shaping materials such as metal cans, buckets, or huge pipes can also be used.

Copper is a costly metal. If you’re attempting to bend copper for a plumbing job, engaging a trained plumber to bend the pipes may be more cost-effective than purchasing many pipes if your attempts fail.

Bend the pipe with a spring.

Tube-bending springs go within the copper pipe and function as a support to help disperse the force.

Severe bends of up to 180 degrees are possible with tube springs.

Tube springs are available in a variety of sizes to accommodate copper pipes ranging in diameter from 1 to 4-inch to 5/8-inch.

To bend a copper pipe with a tube spring, do

  • Mark the location on the copper tube where you wish to make the bend with an indelible marker. The mark should be placed at the bend’s radius’s outermost point.
  • Remove any burrs from the cut end of the copper pipe.
  • Select the appropriate spring size for the pipe. Some springs fit within the pipe, while others fit around the outside.
  • If the spring is longer than the pipe, after bending the pipe, you may simply extract the spring. Join the spring’s end to a wire if it’s too short.
  • Bend the copper pipe over your knee after cushioning it with a soft towel. To get a smoother bend, move the pipe back and forth to the left and right sides of your knee.
  • Take out the spring. If removing the spring is difficult, try turning it clockwise.

Bend the pipe using sand or salt.

The dense materials packed within the copper pipe generate a similar effect to pipe bending springs.

They keep the bending force from being concentrated in a single place.

The force is instead dispersed throughout the full length of the curve. It is possible to use fine sand and salt.

To bend the pipe using sand or salt:

  • Straighten the copper tube or pipe. It does not have to be exactly straight; it simply has to be straight enough to allow the material to flow.
  • Tape the copper pipe’s bottom with duct tape or electrical tape.
  • Inject sand or salt through a funnel into the copper pipe.
  • Tape the opposite end of the pipe shut.
  • Form the pipe into the appropriate shape.
  • Rip off the tape and empty the container of sand or salt.

Bend the pipe with a pipe-bending tool.

A tube bender is a tiny, affordable, specialized instrument that accomplishes one thing very well. It bends copper and other soft metal pipes to a certain radius of 2 or 3 inches.

A tube bender, which looks like a pair of pliers, is used to insert pipes down the center. A marked gauge specifies the bend’s angle, which ranges from zero to 90 degrees.

The upper section of the tool, known as the shoe, goes along with the bend, ensuring a clean curvature.

A tube bender is a fantastic purchase for anyone who needs to bend copper pipes regularly.

Final Words

Copper pipes are widely used in plumbing, air conditioning and refrigeration, fire sprinklers, and crafts.

Copper pipes are bent using the best quality copper tube bender or common household items, such as springs or sand.

Each technique differs in terms of simplicity of usage and the smoothness of the finish after bending.
