Washing Machine Hookup Box

I have the box in the photo that I want to connect to 1/2 CPVC water lines. The valve connections are machined inside to solder to copper. I want to use the outside threads and use a Metal/CPVC female adapter but not sure if these threads will work. Are they 1/2 inch pipe threads. The CPVC female adapter in
Photo seems to go on OK but I want to use one of those that has a factory Metal to CPVC connection and screws on like the plain CPVC female in photo.

I'd solder a female adapter then use a male CPVC adapter. Screwing brass into plastic is asking for trouble. Plastic into brass is less likely to fail.

Most of the ones I've seen are running threads, not IPS. I've seen people jam copper female adaptors on there and get them to seal. I wouldn't try it though. If you really really don't want to solder they make those boxes with PEX outlets. Get one and use a pex female adapter and a CPVC male adapter to convert over. You'd have to invest in a pex crimper though. I'd suggest just finding someone to make the sweat connections for you or getting what you need to do it and learning how.
