Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won't have to worry about matching exact threads when you're on the jobNPT threads may look similar to ISO 71 threads However, ISO and NPT threads should not be mixed The fitting they will show you will most likely be a 1/4″ NPT You will look at the diameter of the thread, and say to yourself, this ain't no 1/4″ fitting but it will be The actual diameter of the 1/4″ NPT thread will be just over 1/2″ The size of an NPT fitting, the 1/4″, the 3/8″, 1/2″ and so on are reference sizes
As a general "rule of thumb" an NPT thread is approximately 1/4″ (025") larger than its "name" For a 1/4″ NPT fitting the "nominal" OD is 0533" NPT fittings are slightly tapered so the "nominal" diameter is the diameter in the middle of the threaded portion, as measured by the top (crest) of the threadsNPT, ISO/BSP, and SAE threadsSelect precisionmanufactured Swagelok fittings, adapters, and more in a range of sizes and materials to suit your application Pipe Fittings Features 1/16 to 1 in sizes;

NPT Thread Sizes – Commonly used NPT thread sizes including 1/8, 1/4, 3/8, 1/2, 3/4, 1, 11/4, 11/2, 2, 21/2, 3, 4, 5, and 6 inches, can be found on most US pipes and fittings The thread sizes smaller than 1/8 inch and larger than 6 inches are occasionally used for specific purposes – The pipe size in the NPT thread sizes chart does1 inch = 254 mm;NPT threads are not interchangeable with NPS National Pipe Straight threads Example Typical Designation of NPT thread 1⁄8–27 NPT;

Female NPT is either FPT or FNPT Pipe 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 identification For example, a 1" MPT pipe thread has an outside diameter of 1315" NPT Size Thread Diameter OD of MPT (ID of FPT will be slightly less than this) 1/8" 0405" 1/4" 0540" 3/8" 0675" The angle between the taper and the center axis of the pipe is tan −1 (1 ⁄ 32) ≈ 173° ≈ 1° 47′ The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the symbol NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizesAs a general "rule of thumb" an NPTthread is approximately 1/4″ (025") larger than its "name" For a 1/4″ NPTfitting the "nominal" OD is 0533" NPTfittings are slightly tapered so the "nominal" diameter is the diameter in the middle of the threaded portion, as
316 stainless steel, brass, and carbon steel; NPT fittings are listed by the "standard" inner diameter (ID) of the fitting (We put "standard" in quotes because the ID of the fitting will vary, depending on the manufacturer) The outer diameter (OD) of the threads is usually about 1/4 (0250) in larger than the stated ID sizeThis 1/4" PTFE bulkhead has an outside diameter of 111/16" and overall length of 13/4" Maximum tank wall thickness is 1/2" Minimum tank diameter is 13" Fitting weighs 0 lbs Hole size required is 13/16" PFA encapsulated Orings
NPT sizes are the most commonly used fitting sizes for general plumbing, piping, and tubing use;Pipe sizes do not refer to any physical dimensions To determine the size of a pipe, the outside diameter of each pipe or fitting must be measured and compared to the table for size identification For example, a 3/4" NPT pipe thread has an outside diameter of 1050 inches Each thread size has a defined number of threads per inch (TPI)1/4 " 9/32 " 5/16 " 3/8 " 25/64 " 13/32 " 27/64 " 7/16 " 29/64 " 15/32 " 31/64 " 1/2 " 33/64 " 35/64 " 9/16 " 37/64 " 19/32 " 39/64 " 5/8 " 41/64 " 21/32 " 43/64 " 11/16 " 45/64 " 23/32 " 47/64 " 3/4 " 49/64 " 25/32 " 51/64 " 13/16 " 53/64 " 27/32 " 55/64 " 7/8 " 57/64 " 29/32 " 59/64 " 15/16 " 61/64 " 31/32 " 63/64 " 1" 1 1/64 " 1 1/32 " 1 3/64 " 1 1/16 " 1 5/64 " 1 3/32 " 1 7/64 " 112" 1 1/8 " 1 9/64 "
