I am running a new dedicated supply branch off my main for exterior hose connections. I cut this branch in just after my pressure tank & sediment filter, but before my softener. Right now the branch ends with a 3/4" threaded valve. Before I run my pex lines out to where I want the sillcocks, I was thinking of making provisions for draining & blowing out these lines come winter.
What do you normally do for blow-out fittings? Tee with threaded adapter that will accept air fitting for blowing out, and a brass plug when in use for water?
I'm just looking for some ideas on what to set up.
Thanks

If you want to avoid threading and unthreading in the future, here are a couple of suggestions
1) Sillcock on the branch. Then you can just use a female garden hose fitting with a air hose quick coupler attached to blow out the lines. No tools or teflon tape needed.
2)Another shutoff valve on the branch with a air hose coupler attached. No need for any fittings at all in the future.

Thanks George. So in both of these suggestions, you're blowing out of the house, not from the sillcock in right?

yes, blow air from inside to outside.
as suggested, thread in another tee with a hose valve installed in one of the ports. on the third port thread in your pex adapter and as many tees as you want for outside faucets.

Thanks. Do you guys normally run 1/2" or 3/4" pex for hose lines?
I'm on a well so I try not to use a lot of water outside (also working on rain storage system). Think 1/2" will be sufficient for occasional use?

take a look at the ID of a 1/2" pex adapter that would be in the end of an outside faucet. then tell me if it makes sense to run 3/4 to it.
HINT.. it is pretty small
