National Pipe Thread Taper (NPT) is a American standard for tapered threads used on threaded pipes and fittings, popular in the oil and gas industry. NPT and NPTF hand taps produce a taper thread form whose diameter increases or decreases along the length of the thread.
All NPT (National Pipe Taper) hand taps from Presto are available in sets or as individual taps (first/taper, second, plug/bottom hand taps). Hand taps are all straight fluted and can be used as machine taps if required. Buy today from Cutwel for next day FREE delivery and the best prices.
