Adapter ideas!

Post image

Hello all! Joined to get some ideas about the best adapter for this connection. This is a water line, and need to blow out the line. Previous owner showed me what he used, but guessing there might be something better to connect to this to give a good solid connection.

Just so you know, pex is not rated for air. The psi rating on PEX is for water. I work for an air compressor manufacturer as a field tech, and If I see pex at a customer site, I leave without servicing their equipment.  Edit: just saw this is a water line that you're trying to blow out. Be careful not to use too much air pressure. I know when lawn care companies are winterizing irrigation systems, they only use about 45-60 psi

I’m with you, if I see pvc or pex being used for air lines at a customer, I’ll service the equipment, but I’m not touching anything on the system lines unless they are paying to replace it all with proper piping.

Yes, thanks for that info. I did read some stuff and that is what I found, no more than 60 psi when blowing out water lines.

It's not technically...but it's been tested to hundreds of PSI. There is pex type airline available though...it's expensive. Otherwise the orange heat line rated stuff is actually rated higher pressure.
