Can I Use an Expander Tool on a PEX-B Pipe?
Today, cross-linked polyethylene (PEX) is one of the most popular types of piping materials. It has many advantages: it is versatile, easy to install, and resistant to different temperatures and other stresses. While PEX-A, PEX-B, and PEX-C have profoundly distinct characteristics, the methods used to join them differ. The two central and fairly typical queries are whether an expander tool compatible with PEX-A can also be used with PEX-B. This article will examine the possibility of PEX-B working with expander tools, the right approach to using PEX-B, and the consequences of choosing the wrong tool when working on your plumbing project.
What is PEX-B?
PEX-B stands for Polyethylene Cross-linked with an Electron beam and is one of the types of PEX tubing that is rigid and comparatively cheaper than PEX-A and PEX-C. It is produced using silane, which gives it excellent chemical resistance, adhesion, and adequate durability. PEX-B is slightly more rigid than PEX-A but is also quite popular among different plumbing types because of its reasonably good performance-to-price ratio.
What is the PEX Expander Tool?
PEX expander or PEX expansion tool, like the iCrimp PEX Expander Tool, is suitable for use with the PEX-A series of tubing. PEX-A expands the end of the pipe to be put on a fitting as it is used in plumbing applications. After the fitting is in, they pull the pipe back into its standard shape, meaning that the pipe and the fitting are fitted so it cannot leak. This method exploits the PEX-A's easy-to-shape malleable property and ability to retain the shape imparted to it.
Can You Use an Expander Tool on PEX-B?
Even though PEX-B is widely used for DTs, PEX-B piping material is incompatible with an expander tool. Here's why:
- Material Properties: PEX-B has lesser shape memory and elasticity than PEX-A. The expansion method is built on such features to provide a protected connection. Since PEX-B is rigid, the pipe will not shrink correctly after expanding, causing poor sealing problems.
- Connection Methods: PEX-B is joined by compression, some crimp technique, or cinch like the iCrimp PEX Crimping Tool Set, which involves squeezing a metal ring or clamp around the pipe and fitting it to make a joint. These methods are appropriate for PEX-B and provide proper connection due to their inherent qualities.

Risks of Using an Expander Tool on PEX-B
Using an expander tool on PEX-B can lead to several issues, including:
- Leaks: Since this expansion method does not apply effective contraction to join the pipes, there will be a chance that the connection is not tight; hence, leakage is likely.
- Reduced Durability: Misconnections can cause low-quality connections and weaken the structure of the plumbing system; hence, it may lead to failure and costly irreparable damages.
- Invalidated Warranties: Mixing application tools and methods from different manufacturers can also nullify warranties, leaving you unprotected in system breakdowns.
Recommended Connection Methods With PEX-B
To ensure a reliable and durable PEX-B plumbing system, use the following connection methods:
- Crimp Method: A crimping tool and copper or stainless-steel rings are applied to connect. The crimping method is commonly employed, and the general rule regarding sealing is that the more intense the crimping, the stronger the sealing will be. An ideal example is the iCrimp PEX Crimping Tool Set.
- The Cinch (Clamp) Method: Involves two tools – the cinch tool and the stainless-steel clamps. It is pretty simple to use and creates a secure connection. A good example is the iCrimp Cinch Clamp Tools.
- Push-Fit Method: They are effortless and do not need special tools to fix push-fit fittings. They are recommended, especially when one wants to make some minor fix and do not know how to do it. A good example is the iCrimp PEX Push to Connect fitting.

Proper Installation Techniques
- Clean Cuts: Ensure the PEX-B pipe is properly cut and perpendicular to seal the connection at the right place.
- Deburring: To achieve proper and tight fittings, always recommended that all the burrs on the cut ends of the pipe be stripped off.
- Tool Quality: Employ special tools of high quality appropriate to the selected type of joining. It will also help reduce the rate of errors, hence enhancing the reliability and consistency of the results.
Bottom line
Though the PEX expander tool is widely used for the PEX-A tubing, it cannot apply to the use along with the PEX-B tubing. There are crimp, cinch, or push-fit connection methods for the PEX-B specification, which guarantees leak-proof joints. By following all the correct procedures of PEX-B, it will be illustrated that the effectiveness of the plumbing system will be retained for a long time and with extended durability. It is advisable to consult the manufacturer to get the proper installations for plumbing processes and use the right tools and fittings from iCrimp.
