Brass SAE 45° Flare Union Fitting — Male Flare Tube Connector
Connect two flared copper, brass, or aluminum tubes of the same size with this brass SAE 45° flare union. Machined from solid brass for corrosion resistance and a leak-tight seal, it uses the standard SAE 45-degree cone flare (SAE J512) found throughout air, fuel, and refrigerant systems. Ideal for air compressor plumbing, instrument lines, and low-pressure fluid connections.
