Male Unions

Brass 45* flare fittings are a brass fitting with a 45* flared end which creates a sealed connection usually used with brass and copper tubing. Male unions feature flared tube connectors on both ends for joining two pieces of pipe. These fittings can be used with air, cutting oil, diesel fuel, fuel oil, mineral oil, refrigerant and water. They are highly corrosion resistant and can withstand up to 2,800 PSI.
