Inverted flare male branch tees are used on hydraulic brake, transmission and fuel lines as well as LP gas lines to connect tubing to mating fittings etc. The male branch tee features two sides with female inverted flare pipe and male pipe thread on the top for threading into internally thread mating fittings. The internal inverted flare creates a strong metal to metal seal. They come in alternating tube/pipe sizes depending on the application. They are made of brass for high corrosion resistance and can withstand up to 2,800 PSI. Used on copper, brass and steel tubing.
