The data includes nominal sizes, major and minor diameters measured in millimeters, and the Threads Per Inch (TPI) count for various sizes ranging from 1/16 to 3 inches. Additionally, it details corresponding nominal pipe dimensions, including diameter in millimeters and wall thickness, providing essential engineering data for industrial plumbing and mechanical applications. The information is systematically organized to assist engineers and technicians in identifying, selecting, and verifying pipe thread compatibility. This reference guide serves as a reliable resource for ensuring accurate fittings and connections in fluid power and piping systems, adhering to standard British piping specifications for high-precision manufacturing environments and general utility pipe installations.",{"@graph":63,"@context":119},[64,80,102],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":51,"@type":70,"position":76},"https://docshare.wps.com/template/general/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/bspp-and-bspt-thread-charts-technical-reference/565595/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/bspp-and-bspt-thread-charts-technical-reference/565595.png","ImageObject",442,249,{"name":88,"@type":89},"Margaret","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-29","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":101},"InteractionCounter",{"@type":100},"ViewAction",9,{"@type":103,"mainEntity":104},"FAQPage",[105,111,115],{"name":106,"@type":107,"acceptedAnswer":108},"What does BSPP stand for in the context of this document?","Question",{"text":109,"@type":110},"BSPP stands for British Standard Pipe Parallel, which refers to a type of thread standard used for plumbing and pipe fittings where the threads have a constant diameter.","Answer",{"name":112,"@type":107,"acceptedAnswer":113},"How is the TPI (Threads Per Inch) determined for G 1/16 pipes?",{"text":114,"@type":110},"According to the provided BSPP chart, a G 1/16 pipe has a TPI of 28, indicating that there are 28 threads per inch along the length of the thread.",{"name":116,"@type":107,"acceptedAnswer":117},"What is the difference between BSPP and BSPT threads?",{"text":118,"@type":110},"BSPP threads are parallel, meaning they maintain a constant diameter, whereas BSPT (British Standard Pipe Tapered) threads are tapered, meaning the diameter gradually increases or decreases along the length of the thread, typically used for creating a self-sealing joint.","https://schema.org",{"og:url":78,"og:type":121,"og:title":59,"og:site_name":91,"og:description":61},"article",{"robots":123,"canonical":78},"index,follow",{"doc_id":125,"site_id":56},565595,1792097049,{"code":4,"msg":5,"data":128},{"doc_id":125,"user_id":129,"nickname":88,"user_avatar":130,"doc_module":9,"category_id":50,"category_name":51,"doc_title":59,"doc_description":61,"doc_content":131,"file_id":132,"file_url":133,"file_type":134,"file_size":135,"view_count":101,"is_deleted":4,"is_public":9,"is_downloadable":9,"audit_status":9,"page_count":9,"language":136,"language_code":57,"site_id":56,"html_lang":57,"table_of_contents":137,"faqs":138,"seo_title":139,"seo_description":61,"update_tm":140,"read_time":4},137451207643,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","British Standard Pipe-BSPP & BSPT  \nBSPP  \n\n| NOMINAL THREAD SIZE (inch) | MAJOR DIAMETER (mm) | MINOR DIAMETER (mm) | TPI |\n| --- | --- | --- | --- |\n| G 1/16 | 7.723 | 6.561 | 28 |\n| G 1/8 | 9.728 | 8.566 | 28 |\n| G 1/4 | 13.157 | 11.445 | 19 |\n| G 3/8 | 16.662 | 14.950 | 19 |\n| G 1/2 | 20.955 | 18.631 | 14 |\n| G 3/4 | 26.441 | 24.117 | 14 |\n| G 1 | 33.249 | 30.291 | 11 |\n| G 1 1/4 | 41.910 | 38.952 | 11 |\n| G 1 1/2 | 47.803 | 44.845 | 11 |\n| G 2 | 59.614 | 56.656 | 11 |\n| G 2 1/2 | 75.184 | 72.226 | 11 |\n| G 3 | 87.884 | 84.962 | 11 |\n\nBSPT  \n\n| MALE TAPERED THREAD SIZE (inch) | FEMALE PARALLEL THREAD SIZE (inch) | MAJOR DIAMETER\u003Cbr>(mm) | MINOR FEMALE DIAMETER (mm) | TPI |\n| --- | --- | --- | --- | --- |\n| R 1/16 | Rp 1/16 | 7.723 | 6.490 | 28 |\n| R 1/8 | Rp 1/8 | 9.728 | 8.495 | 28 |\n| R 1/4 | Rp 1/4 | 13.157 | 11.341 | 19 |\n| R 3/8 | Rp 3/8 | 16.662 | 14.846 | 19 |\n| R 1/2 | Rp 1/2 | 20.955 | 18.489 | 14 |\n| R 3/4 | Rp 3/4 | 26.441 | 23.975 | 14 |\n| R 1 | Rp 1 | 33.249 | 30.111 | 11 |\n| R 2 | Rp 2 | 59.614 | 56.476 | 11 |\n\nBRITISH STANDARD PIPE DIMENSIONS FOR UNIFIED THREAD SIZES  \n\n| MALE TAPERED THREAD SIZE (inch) | CORRESPONDING PIPE |  |  |\n| --- | --- | --- | --- |\n|  | DN (mm) | ACTUAL OD (mm) | WALL (mm) |\n| 1/16 | 3 | -
