best/correct way to connect a anti frost bib to ProPex
1. What is the best/correct method for connecting my anti frost hose bib to ProPex Upinor(Wirsbo) Expansion piping. A brass female connector like this?

2. Are there direct to ProPex antifrost bibs?

3. What is the best way to mount this hose bib to cinderblock? My plumber suggested a 2x8 or similar chunk of wood mounted to the cinderblock with tap-cons and then the hose bib mounted to the wood. I would use cedar/redwood or similar, or perhaps a steel plate?

Existing hose bib was cemented in place through the cinderblock and not screwed in.

I have the same tubing in my house. I attached a 12 inch long copper pipe to the propex inside the house using a pex/copper fitting, and used a copper frost free hose bib. I like the idea of a wooden board attachment point for the hosebib, either PT or rot resistant wood is necessary

That fitting will work if you have a 1/2 MPT hose bib.

I like to also add a shut off valve so if the hose bib fails I do not have to shut the whole house down to fix it.
If the hose is left on and it freezes the valve can fail, happens all the time.
I use a lot of vinyl lumber for trim so I use 1 X 6 vinyl and rout an ogee of just cut a slight angle around the outside edges to mount the valve.

It's also nice to anchor the hose bib inside a wall or crawl space as well- especially when using pex

Thanks for all the answers.

@joecaption - on the inside the hose bib goes into joist space between a daylight basement and the upper floor. I can see the benefit of putting in a shut off valve but my plumber said you dont want one in your living space. Worth it to make a framed in box for it and a cover panel?

@Daniel Holzman - did you go hose bib -> copper pipe -> pex or was the hose bib just copper itself? Are you saying you went an extra 12" past the hose bib male end into the house? If so why?

@TheEplumber - This makes sense how do you anchor it internally? Mine will be coming in through 1 or 2 joists before it meets the pex.
