PEX used with Wirsbo Expander Tools

The Wirsbo Expander Tool can only be used with PEX-a quality tubing. PEX can be made using three distinct processes, creating PEX-a, PEX-b, and PEX-c quality. PEX-a is the highest quality PEX available, the PEX that is most uniform in nature and the PEX that is able to keep a memory of its shape and return to that shape after expansion. When using the Wirsbo Expander Tool, you will stretch the PEX tubing out to the point where PEX-b or PEX-c would not come back, and thus would not create a secure connection. PEX-a's superior quality allows it to be expanded to fit over the fittings and within seconds return to its shape forming snugly around the newly inserted fitting.
