WebNPTF (National Pipe Thread) pipe threads are engineered with the same thread angle and pitch as NPT threads, but carefully machined to avoid the spiral leak path inherent to NPT threads. This design – at least in theory – avoids the need to use sealant with NPTF threads to achieve a pressure-tight seal between male and female pieces, which is why … WebTapered pipe thread plug gauges use L-1, L-3, and 6-Step gauges to perform similar tolerance checks. The L-1 and L-3 gauges are threaded, while the 6-Step is plain/smooth. An assembly includes a double-ended Taperlock handle with both Go and No-Go gauge members. All gauges are marked with nominal size and gauge type, and are right …

Web16 sep. 2024 · NPT/NPTF Thread Type – National Pipe Tapered Fuel This thread type is most commonly used in North America. You’ll recognize it by its tapered outer and inner diameter which is self-sealing. When torqued the flanks of the threads compress against each other forming a leak-tight seal. National Pipe Taper Fuel (NPTF, also called Dryseal American National Standard Taper Pipe Thread, defined by ASME B1.20.3) is designed to provide a more leak-free seal without the use of PTFE tape (often referred to by the popular brand name "Teflon") or another sealant compound.
