WIRSBO Vs PEX Pipes Comparison of 2023 – New Guide

Being a plumber, you just sealed the contract to plumb the latest house in town. And you need to secure the best tubing for it. But you are not sure whether to go for Wirsbo or PEX. And the most salient questions on your mind are:

what are the differences between the Wirsbo vs PEX pipe? Which is better between them? The answer to your questions isn’t complex. Both tubings are the same — Wirsbo is PEX, and Pex can be Wirsbo too.

PEX is actually the generic name for Cross-linked(X) Polyethylene. And this is a well-known type of plastic used around the world. Wirsbo, on the other hand, is one of the brand names of the PEX tubing.

Therefore, the question is not the difference between Wirsbo and PEX, but the actual classifications of the Cross-linked Polyethylene.

WIRSBO Vs PEX Pipes – Comparison 2023

WIRSBO Pipe Review

WIRSBO Pipe Review

The Wirsbo is one of the brand names under the PEX-A pipe. It’s actually the first and by far, the most famous brand of PEX-A tubing. So Wirsbo is PEX A.

PEX-A isn’t also the only type of PEX tubing. There are two others, PEX B and PEX C. This classification stems from the process applied in the manufacture of each type of PEX tubing.

In the manufacturing of the PEX-A pipe, there’s a cross-linking with an “engel” process (a process involving the mixing of 2% peroxides and high-density polyethylene).

This mixture is done at a low temperature and then cross-linked at an elevated temperature of between 200 and 250 degrees. The polyethylene melts into a liquid state, and the peroxide causes it to cross-link and this, yielding a cross-linked network of 80 to 83%.

This network has great flexibility. It’s also uniform. And has a low tension. It’s generally firmer and softer than other PEX types.

Understanding different types of PEX tubing will help you chose from the myriads of brands available in the market. Aside from Wirsbo, other top brands of PEX-A pipe include Mr. Pex, Uponor, and Rehau.

PEX Pipe Review

PEX Pipe Review

As captured before in this article, Wirsbo tubing is only a brand name of the PEX-A type tubing. There are Other PEX types. And they include PEX B and C. We will look at the brands under these PEX types.

However, you need to note that as opposed to PEX-A, B and C are cross-linked after extrusion. PEX B is made with a silane or moisture cure.

And a high-density polyethylene is formed by means of a catalyst. Afterward, the mixture is steam bathed, and this gets it cross-linked.

PEX C, on the other hand, is made by electrical irradiation. Crosslinking is achieved by exposing the pipe to an electron radiation beam. Irradiation will break existing links and initiate cross-linking.

PEX B is widely used. It’s arguably the most popular type of PEX tubing. It is also closely related to PEX C.

Only that PEX C is softer, owing to the percentage of polyethylene that gets cross-linked. PEX B has 65% to 70% cross-linking, whereas PEX C has 70 to 75% cross-linking.

Comparison of WIRSBO vs PEX Tubings

Let’s see how both tubings compare:


Wirsbo(PEX A) has the same type of configuration with the PEX B and PEX C. Same dimension and same finishing.


Wirsbo Brand affords you more expansion and flexibility. And so it’s really easy to work on because you can easily twist it to any direction you want.

On the other hand, it’s a little difficult to work with PEX B and PEX C. Owing to this, the Wirsbo brand is more expensive than PEX B and PEX C.

Fixing a Kink

You can fix a kink with a heat gun while working on a Wirsbo tubing, whereas with PEX C and PEX B, you only have the option of cutting off the affected part and mending it with two pieces of PEX.


The Wirsbo Brand has the highest strength because it features the highest cross-linking of 80 – 83%. PEX has cross-linking between 65- 75%, respectively.

Working Temperature Conditions

Again, Wirsbo tubing will more likely burst in extremely cold temperatures. On the other hand, PEX B and PEX C have greater expandability and so hold up well in very low temperatures.

Leaching Chemicals

Wirsbo pipe is also more likely to leach chemicals, whereas Pex B and PEX C types will less likely do that, thanks to the oxygen barrier system.


We will draw the curtains here in this Wirsbo vs PEX pipe comparison.
With this exhaustive review, you now know what PEX type you are buying.

And why you are buying it. You have known the strengths and weaknesses of different PEX types. So you are adequately informed to pick any one that suits your style.

  1. Mark,
    I am helping to renovate a house for Habitat for Humanity that has a fire sprinkler system using WIRSBO Aquapex 1006 1/2″ SDR9/ B1375potable 130psi tubing Wirsbo-Pex-a Tubing CB060612 20760. We are trying to determine what foam or caulk is compatible (if any) with this tubing for air sealing purposes. We are contemplating installing a “hat over each recessed sprinkler head and sealing around the tubing and the “hat to the sheetrock on the ceiling. Then blowing in loose cellulose over everything. Any insight would be appreciated.
