Designed for air brake system connections, this 1/4-inch brass tee adapter combines a push-to-connect female inlet, a 1/4-inch male NPTF thread, and a push-to-connect female outlet in a compact three-port configuration. The Danfoss / Eaton Brass Adapter is part of the Weatherhead line by Aeroquip and is suited for routing or branching air lines where a swivel tee or Y arrangement is required.
Constructed from brass with Dura-Kote plating, the fitting offers corrosion resistance appropriate for demanding air brake environments. Operating pressures exceed SAE standards, and the push-to-connect ends allow for tool-free line attachment. Note that this fitting is rated for air brake use only, it is not intended for fuel, water, or oil service, and should not be used in applications where temperatures exceed 200°F or where battery acid exposure is possible.

Is this here adapter okay for use on semi-truck air brakes?
