yes, this a 30 deg chanfer. See full answer »

NPT (National Pipe Taper) threads are designed to provide a mechanical seal by tightening the male and female threads together, while NPTF (National Pipe Taper Fuel) threads are designed to create a dry seal without the need for sealants, thanks to their tighter tolerances and interference fit. Essentially, NPTF threads offer a more leak-proof connection compared to standard NPT threads. See full answer »

NPTF stands for National Pipe Taper Fuel, which is a type of tapered pipe thread used for creating pressure-tight seals in piping systems. Unlike NPT (National Pipe Taper) threads, NPTF threads are designed to create a dry seal without the need for additional sealing compounds or tape. See full answer »

Yes, there is a difference between NPT (National Pipe Taper) and NPTF (National Pipe Taper Fuel). NPT threads are designed primarily for sealing with the use of a sealing compound, while NPTF threads have a more precise thread form and are designed to create a dry seal without the need for a sealant, making them suitable for fuel and high-pressure applications.
