Push-in fittings are unique in that they provide a very easy installation and are less bulky than compression fittings for low clearance situations. Female straight fittings feature a tube connector on one end and male pipe thread on the other for threading into internally threaded mating parts. They come with either the same size tube/pipe or alternating tube/pipe 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.
