How to select the right OSG pipe tap for NPT threading?

Select an OSG pipe tap based on thread size (e.g., 1"-11.5 NPT), material compatibility, and tap design. For tough materials, choose a cobalt steel tap with interrupted threads and V coating, like this model, to reduce torque and improve chip evacuation. Always match the tap to the specific NPT standard.
