Designed for air brake system applications, this brass tee adapter from the Weatherhead line by Aeroquip connects push-to-connect and threaded fittings in a single compact body. The configuration features two female push-to-connect ends and one male NPTF end, all sized at 1/4 inch, making it well-suited for branching air lines where a reliable, leak-resistant junction is needed.
The Danfoss / Eaton Brass Adapter is finished with Dura-Kote plating, which provides strong resistance to corrosion in demanding environments. Rated for higher operating pressures than standard SAE requirements, it is built to handle the demands of commercial air brake circuits. Note that this fitting is not rated for use with fuel, water, or oil, and should not be used in applications where temperatures exceed 200°F or where battery acid exposure is possible.

Question by: Harold B on Jul 15, 2025, 4:45 PM
Reckon this'll hold up alright in a system that sees a fair bit of vibration?
Answer by: Customer Support on Jul 17, 2025, 4:09 PM
Dura-Kote plating on this Danfoss/Eaton brass adapter gives it good corrosion resistance, and it's rated for higher operating pressures than standard SAE requirements, so it should handle vibration pretty well in air brake systems.
