www.stpats.comPipe thread sizes do not refer to any physical dimension. The outside diameter of each pipe fitting must be measured and compared to the table for size identi-fication. For example, a 1” MPT pipe thread has an outside diameter of 1.315” NPT Size Thread Diameter OD of MPT (ID of FPT will be slightly less than this.) 1/8” 0.405” 1/4” 0 ...
Thread and Connector Identification - Gerrard Hydraulics
www.gerrardhydraulics.com.auNPSM is NATIONAL PIPE STRAIGHT MECHANICAL Thread form per ANSI/ASME B1.20.1 National Pipe threads are similar in function to BSP threads, but are not generally interchangeable. NPTF threads (also known as Dryseal) are an improvement to NPT. Controlled truncation of threads mean the metal-to-metal thread seal is at root and crest of threads, in ...

mae.ufl.eduThe most common types of pipe thread are: • NPT - American Taper Pipe Thread = National Pipe Taper • NPTF - American Taper Pipe Thread for Dryseal joint without sealant compound = National Pipe Taper Fuel NPT and NPTF appear to be identical. Both have the same pitch diameter at the top of the hole of the internal thread or end of the pipe ...
Hydraulic Fitting Thread Identification Manual U.S.A. 2014
www.dieselduck.infoAlso known as American Dryseal Pipe Threads, the thread types include NPTF, NPSF and NPSM. N – National S – Straight Thread F – Fuels P – Pipe T – Tapered Thread M – Mechanical Joint Pipe threads can be either straight or tapered. The first step in identifying this fitting is to determine if the thread is parallel (straight)

www.parker.comSize: Pipe thread sizes are designated by the number of sixteenths of an inch. (3/8 NPT pipe = 6/16 = 6) Thread Type: All pipe threads are National Pipe Taper (NPT) unless otherwise designated. Straights and Elbows: Call out the largest pipe end first followed by the smaller pipe size. See MHN example on page 4.
