Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, polybutylene piping systems were viewed as “the pipe of the future” and were used as a substitute for traditional copper piping.
Is Uponor and Pex the Same?
Uponor (formerly wirsbo) has been making pex pipe for radiant floor heating since 1970, longer than any other pex manufacturer.

I have only seen apollo expansion fittings and all pex expansion fittings will only work with pex-a due to the i.d. If you have uponor, you have pex-a tubing.
What’s the Difference between Pex and Polybutylene Pipe?
There are two common types of plastic piping which are known as pb (polybutylene) and pex (cross-linked polyethylene). The main difference between pb and pex is in how the material is created. The polymer chains in pex are bonded to each other; this is called cross-linking and does not happen in pb pipes.
How can you tell the difference between pex and polybutylene? Polybutylene pipe was commonly used from 1978 – 1995 and is a gray flexible pipe. Pex is a plastic flexible pipe that comes in white, blue, orange, red and a translucent milky white clear. This piping came about to replace polybutylene plumbing.
Can pex fittings be used on polybutylene? Pb has the same outside diameter as pex of the same nominal size, but outside diameters differ slightly between the tubing types. This means that you should not use pex fittings on polybutylene, but that you can use pex crimping rings and pex crimping tools on barbed pb connections.
Can you use pex sharkbite on polybutylene? Sharkbite pex fittings make it easy to transition between pipe types during repairs. Fast, efficient and reliable, our transition fittings are compatible with polybutylene, pex, pvc, cpvc, pe-rt and sdr-9 hdpe, and are approved for behind-the-wall installation as well as burial.

What year did they stop using polybutylene pipes? Because of numerous leakage problems and lawsuits against the manufacturers, polybutylene pipe (pb) manufacture was stopped after 1995. It is no longer an approved pipe for water supply or distribution by the building codes, although approval was not immediately rescinded after it was removed from the market.
Which is Better Pex or Polybutylene?
