Specification Brand : Generic BulletPoint1 : 1/2 NPT Measures 7/8 inch! NPT (National Pipe Thread) sizes are unique. If you use a ruler to measure these you will end up with the wrong part! Please note: A 1/4 NPT measures 1/2 inch on a ruler. If you measured your old fitting's threads and they were close to 1/2 inch on a tape measure then you need a 1/4 NPT, not a 1/2 NPT!
