Hose connection brass upgrade

Hose connection brass upgrade for all EX oxygen concentrator machines (e.g. ex-5, ex-10, ex-15, and ex-20). This part replaces the plastic connection on the ex machine to hose. The brass fitting will not strip or cross thread if you are having issues with the plastic fitting, this is your solution! *Kits are all made to order so some components may not be in stock when ordered.
