Note on Thread Size - Thread Size (NPT) does NOT refer to the physical dimension of the pipe or fitting. Please refer to the table below if you're unsure of which size to buy. For example, a 1/4" NPT pipe thread (common air tool fitting size) has an outer diameter of 0.540".

Outside Diameter (OD/inches) = Pipe Thread Size (NPT)

• 13/32 (.405") = 1/8" NPT
• 35/64 (.540") = 1/4" NPT
• 43/64 (.675") = 3/8" NPT
• 27/32 (.840") = 1/2" NPT
• 1-3/64 (1.050") = 3/4" NPT
