Sizesand dimensions of pipes and tubes, and their fittings - inside and outside diameter, weight and more. Threads Thread data - metric, unified, ACME and others. Related Documents . ANSI B1.20.1 - NPT - American National Standard Taper Pipe Threads NPT and NPTF pipe threads - dimensions according ANSI/ASME B. British Pipeswivel adapters are manufactured in accordance to SAE J514 specifications, and thus are designed to work in conjunc-tion with several manufacturers’ hose and adapter products. Unlike most pipe thread connections, NPSM swivel adapters do not seal on the threads. NPSM swivel connections incorpo-rate parallel threads, as opposed to tapered. TheTechnical Bulletin #24 “ NPSF, NPSI and PTF-SAE Short Gages” deals with short dryseal pipe threads. Phone: 817-870-8888 Fax: 817-870-9199 E-mail: sales@greensladeandcompany.com. 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? SAE45° Flare – SAE J512 Threads Dimensions. SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve. 7/16 – 20, 1/2 – 20, 3/4 – 16 & 7/8 – 14 are the same thread form as JIC 37° flare. Some fittings in these sizes have both JIC 37° & SAE 45° seats. TheASME B16.11 Pipe Fittings Dimensions are perfect for providing quick and swift piping connections at an affordable price.
