How Can You Propress Soft Copper?

Soft copper pipes are propress for plumbing, air-conditioning and heating systems. This copper pipe connection process is less time-consuming, more effective and long-lasting. ProPress is just a process of connecting soft copper pipes, as soft coppers are flexible and easy to bend.

3 Easy Steps For Propressing Soft Copper

Necessary Tools

To propress soft copper, there are some must-needed tools to use. These tools are enlisted down- 

  1. ProPress equipment
  2. Copper pipes
  3. Coupling(Veiga couplings are good)
  4. Cutter
  5. Sharpening tool
  6. Deburring Instrument

Step1.Cut and Clean

Firstly you need to measure and cut the pipes. After cutting the pipes, you can use any sort of smoothing tool to remove debris from the inside as well as from the outside. This will provide a perfect and sleek connection.

Step 2. Attach the Coupling

Secondly, select a coupling depending on the pipeline and use. Coupling is a significant component of this processing procedure. After choosing a suitable coupling for your copper pipes, measure the depth of the joint and mark the copper pipe if needed. Gently attach the joint to the pipe’s end.

Step 3.ProPress Copper Pipes

Finally, adhere the pipes by coupling and propress to ensure proper attachment via the propress tool. Make sure to check for the “O Ring” is in the coupling. This “O Ring’ is crucial because it gives extra protection.

How To Maintain Longevity Of Propressed Soft Copper

The propress technique is used for long-lasting connections for pipelines. To maintain this longevity, you need to follow and maintain some recommendations.

1. Follow Manufacturing Recommendations 

Clean and remove any particles or debris from the pipe, and if any part is broken or damaged, replace it as soon as possible.

2. Use Sealer for better protection

High pressure, heat or high circuit may cause a leak which alters the long-lasting power of your propress . Using a Sealer like “Pipe Thread” can give extra support. 

3. Protection From Rust and Chills

Routinely check should be done for rust and other damage. If rust is seen, you must take anti-rust action.

Use an insulating wrap to protect pipelines from chilly weather and maintain the prepress’s longevity. This will help the pipeline work perfectly under harsh conditions.

Advantages Of Propressed Soft Copper

1. Easy and Reliable

Soft copers are flexible and are the best option for plumbing, air-conditioning, etc. ProP dressing of soft copper is an easy and reliable method for proper pipeline connection.

2. Less Time Consuming 

The propress method is easy and less time-consuming than any other joining. Because of this, it has become the most frequently used procedure for connecting pipes.

3. Easy Repair and Modification

Soft copper is flexible, and the propress method is the easiest. This helps in quick modification. This quality also comes in handy in repairing damaged lines as copper is easy to cut, and with propress, you can join them without any effort.

Disadvantage Of Propressed Soft Copper

1. Limitation

Soft copper has less capability than hard copper because it is not a perfect option for high-pressure treatment. Like other drawbacks, it is likely more amenable to dent, collapsing and other damages. So propressing the soft copper needs accurate measurement and components for use.

2. Cost

ProPress is a costly procedure as just a propress tool can cost up to 1500$-3000$. Also, soft is higher than hard copper because of the additional treatment process. This condition makes the propress of soft copper higher than another soldering.

3. Availability 

Depending on region and nation, the availability of soft can get tough. This can cause a sourcing challenge.


1. How Much Pressure Can Soft Copper Hold?

It depends on the thickness and diameter of the tube. Generally, soft copper used for plumbing can hold up to 400-600 psi at room temperature.

2. Can You ProPress in the Ground?

Yes, propressed fittings can be installed for above and ground applications.

But propressed fittings are not recommended to directly use below ground as it can affect the longevity of propressed fittings.

3. Can You Use ProPress for Gas?

Yes, propress can be done on gas installation, but you must follow some regulations, local codes and guidelines. As gas is tough to handle and can create excess pressure inside the pipe, you must carefully use propress for gas line installation.

4. What is the Pressure Rating of Copper ProPress?

Tested pressure rating was 600 psi, but propress typically works under 200 or less.


Proposing is a safe and less time-consuming process for joint copper, stainless steel, pex, etc. pipes. In plumbing, copper is heavily used to join the pipelines. It is a top choice for experts for quick and secure pipeline installation.
