Qest to Pex Coupling

[David York]

Replacing a frost free sillcock and need to convert from Qest to Pex. I plan on using a Sharkbite 1/2-in Pex crimp to 1/2 polybutelene transition. It comes with rings for both pipes but can I crimp both rings with Pex crimpers? Thanks.

I think yes.

Can the same crimp tool (Sharlbite 23251) be used to crimp both the Pex and PB side of the adapter?

Good morning,

Yes. You can use our SharkBite Crimp tools to complete this project as long as the sizes match up - For Example: The Crimp Tool Part Number: 23251 only crimp 1/2inch or 3/4 inch crimps. The Crimp Tool Part Number: 23100 crimps 3/8 inch, 1/2 inch, 3/4 inch or 1 inch crimps.

I am confident that would apply to other brands of crimp too.
