NPT and BSP thread pitches threads per inch TPI are listed below To determine pitch use a thread gauge or count the number of threads that fall into a 1 quot span Note that strictly speaking when we use threads per inch we are actually specifying the inverse of the pitch pitch being in units of length peak to peak Metric threads are usually specified in actual pitch e g The taper rate for all NPT threads is 1⁄16 3⁄4 inch per foot measured by the change of diameter of the pipe thread over distance The angle between the taper and the center axis of the pipe is 1 176 47 ′ 24 quot ″ 1 7899 176 Commonly used sizes are 1 ⁄8 1 ⁄4 3 ⁄8 1⁄ 2 3⁄ 4 1 1 1⁄ 4 1 1⁄ 2 and 2 inch appearing on pipes and fittings by most U S suppliers Sizes 70 Results Nominal Inside Pipe Diameter In 3 8 quot Sort by Top Sellers Top Sellers Most Popular Price Low to High Price High to Low Top Rated Products Get It Fast In Stock at Store Today 15 Cumberland amp nearby stores Next Day Delivery 8 Availability Show Unavailable Products Department Plumbing Pipe amp Fittings Pipe Vinyl Tubes CSST Pipe Black Pipe ISO 7 1 or R Series formerly BSPT BS 21 and DIN 2999 tapered pipe thread has a taper of 3 4 quot per foot or 1 in 16 on the diameter 1 degree 47 minutes or 1 78333 degrees Metric tapered fitting threads use the ISO 7 1 standard but give the measurements in millimeters mm or centimeters cm Universal Thread Stainless SteelPush to Connect Tube Fittings for Air and Water 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
