The Aeronautical National Pipe Taper (ANPT) thread is very similar to the National Taper Pipe (NPT). The difference is, for Navy or Army use, the must be very carefully controlled for taper, diameter and the thread form. At Detroit Nipple Works, we offer ANPT threads from 1/2″ to 2″. There are SAE requirements for ANPT pipe thread. You can view the requirements here.
When it comes to ANPT or NPT they are almost identical up to the 2-inch size. The threads have a requirement of an L1 gage. The benefit of an ANPT thread, is they do not need pipe tape to make a true seal. They are designed to crush in on themselves to make a proper seal. Also, ANPT, like stated earlier, requires L1/L2 ring gauges for their male threads, and L1/L3 gauges for their female threads.
ANPT is used in the more high-end technical fields. Used for a process such as transportation or chemical processing. In addition, this type of thread is seen in industries that need to transport natural gas, gasoline, oil and other chemicals. Aeronautical National Pipe Taper is something Detroit Nipple Works has been familiar with and can meet the high standards of this type of thread.
