NPT, National Pipe Taper, is the American tapered pipe thread standard, sealing on the taper of the thread itself rather than a washer. It's common on US-spec hydraulics, pneumatics and fluid fittings, and isn't interchangeable with BSPT despite the similar function.

Stocked from OSG in spiral flute HSS-E, steam oxide coated, for blind holes. All held in UK stock. Order before 4pm and it ships same day.
