I find "out" to be easy, as brass threads do not corrode into steel all that much. "In" on the other hand, usually frustrates me because the darn valve wants to tighten just past the point I want, and you don't want to crank that brass thread around another 300+ degrees. Then the pipe tap comes out to gently, barely, clean things up 'till I get it to snug up where I want. It helps if you have a box full of valves on hand, as the thread lead start is random, not indexed during manufacture. Sort of like the castle nut or safety-wire drilled bolt that doesn't line up at the proper torque. Try another one. Since you only have one new valve, I feel your pain already.![]()
