The ones that I received were made out of aluminum

5.0These work great!
4WP advertises these as brass, but they are aluminum, which is current production at Power Tank. They are fantastic. Air up and down in no time flat. Installation is easy, watch the video, make your holes straight, and don’t tap too deep. Use pipe dope or locktite, not Teflon tape.
Thanks for the question. The Power Tank Monster Valve is a universal product that requires drilling in to and tapping the rim for a second stem so yes it is compatible with the Interco BirdDog Wheel
