    Abstract - (Show below) - (Hide below)

    Provides a range of tables covering dimensions of flared, inverted flared and compression type fittings in the range 1/8 in. to 1 in. The Standard is intended primarily for the automotive industry, but the fittings are also used extensively in other sections of industry.

    Scope - (Show below) - (Hide below)

    This standard relates to tube fittings of the following types: 45-degree flared ( 1/8- 1 in) Inverted flared ( 1/8- 3/4in) Ball sleeve ( 1/8- 3/4in).The fittings are intended primarily for automotive use, and are screwed Dryseal American Standard Taper Pipe thread (NPTF) and Unified threads.NOTE: Other fittings in common use are screwed with British Standard Pipe taper threads and Unified threads. The BSP thread is similar to the NPTF thread, having the same t.p.i. in the 1/2in and 3/4in sizes, and differing by not more than one t.p.i. in the other sizes. BSP and NPTF threads are, however, not compatible, having different thread forms and methods of sealing, and the fittings are not interchangeable in any sizes.
