Most likely 3/4 galvanized water pipe. And the white stuff is
pipe dope, to help keep the thread from leaking.
Use two pipe wrenches. One to hold the fitting, the other to
apply the torque. The wrenches should face oposite directions.
One opens up, the other opens down.
I got a set of three wrenches, in a case like this I'd use the 18
incher to hold the fitting, and the 24 incher to apply torque.
