Pex Connection to CPVC

I will be making 1/2" PEX to 1/2" CPVC using copper crimp rings. Any recomendations on how these connections should be made? I'm looking at using a male pex to a brass female (with rubber washer) that has cpvc attached for gluing.


Is there a better connection?

I'm a plumber, but I've never used CPVC except to make a minor repair once on an existing system. I'm just curious - why the rubber washer? I know the PEX x male adaptor has a tapered thread (pipe thread), and I would assume the CPVC x female adaptor does also(?) If so, there's no need for the rubber washer - just some teflon tape or pipe dope. Does the washer come with the CPVC fitting, or were you planning to add it?

Edited to add: I just googled it, and saw that the washer is integral to that fitting, so you shouldn't use it with that PEX adaptor. I'd use a CPVC x male adaptor (all plastic):

and a 1/2" PEX x female adaptor (brass):
