ANSIASME B1.20.1: collects the specifications for the NPT thread, replacing the original ANSI B2.1. ANSI B20.3: contains the NPTF thread specifications, replacing the original ANSI B2.2. ANSI B.20.5: contains the specification of the gauges to verify the NPTF thread. Having trouble finding the fittings you need?

BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered thread. An appropriate sealing compound can be used in the thread to ensure a leakproof joint. If you have any questions please contact us or check out our fittings with BSPP/ BSPT (G Ballvalve bore sizes from 3/8 to 2 in.

Sizes smaller than 1/8 inch are occasionally used for compressed air, while sizes larger SizingThe NPT threads sizing chart includes data for external and internal pipe threads. The taper rate for all NPT threads is 1/16—3/4 in. per foot (62.5 mm per m)—which is Couplersare female fittings with threads on both couplers.. Tees are couplers that join three sections of pipe or tubing. They can be a combination of male to female or reduce size. Elbows are couplers with a 90-degree turn.. Bushings are used to convert from one size to another. For example, your bushing could have a 3/8 male Themost common sizes for pressure gauge connections in the U.S. are ⅛-inch NPT, ¼-inch NPT, and ½-inch NPT. The U.S. and Canada also use parallel threads like the NPSM (National Pipe Straight Mechanical) connector. However, this thread type is typically found as a female (internal) component in non-pressurized devices like thermowells. NPT Thread = National Pipe Thread • Taper rate for all NPT threads is 1/16 • The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings 60º Pitch 90º conicity: 6.25% Thread Size M6 M8 M10 M12 M16 M20 M25 M32 M40 M50 M63 Major Dia. in ordepths.

Various industries like Chemical, Machineries and Equipment, Power Stations, etc., uses ASME B16.11 Socket Weld Fittings for safe and seamless operations. The ANSI B16.11 Threaded Pipe Fittings, on the other hand, are TheBSW is the Coarse Thread series of British Standard 84:1956 - Parallel Screw Threads of Whitworth Form. The dimensions given in the tables on the following pages for the major, effective, and minor diameters are, respec- tively, the maximum limits of these diameters for bolts and the minimum limits for nuts. 1/16" - 1 3/4" 1 7/8" - 6". nFTFg.
