NPT Bottoming HSS Tap by Bordo Size:1/8" x 27TPI Textured rubber grip for improvedHSS NPT Bottoming Hand and Machine Tap. National Pipe Tapered is a US standard for tapered threads used to join pipes and fittings. ANSI ASME standard B1. 20. 1 covers threads of 60 form with flat crests and roots. The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other. However a clearance remains between the crests and roots of the threads, resulting in a leakage around this spiral.
