If done correctly Freeze 12 and the others like it all have their own special fittings. That's how you tell whats in the system when you go to evac it. If I suspect a mix or a r12 substitute in the system I will not recover it. It costs me a good deal of money to have my r12 tanks flushed and tested after I accidentally capture one of these blends in my recovery system.
