Push-in fittings are unique in that they provide a very easy installation and are less bulky than compression fittings for low clearance situations. Male run tees feature tube connectors on one side and the top and male pipe thread on the other side for threading into internally threaded mating parts. They come with either the same size tube/pipe or alternating sizes depending on the application. They are designed to resist pull-out, are highly corrosion resistant, and have a maximum working pressure of up to 2,800 PSI.
