British Standard Pipe (BSP) threads, also known as Whitworth threads, are among the most widely used pipe thread standards. The BSPP (parallel) male mates with a BSPP (parallel) female or a female port. The BSPP male has straight threads and a 30° seat. The BSPP female has straight threads and a 30° seat.

The Society of Automotive Engineers (SAE) specifies the use of a 37° flare or seat for high-pressure hydraulic tubing. These are commonly known as JIC couplings. The JIC 37° flare male will mate only with a JIC female. The JIC male has straight threads and a 37° flare. The JIC female has straight threads and a 37° cone seat. The seal is achieved on the 37° flare seat by establishing a line contact between the male flare and the female cone seat. The threads provide the mechanical connection.

The DIN 24° cone male fitting mates with any of the three females listed: female 24° cone with O-Ring, female metric tube fitting, or female Universal 24°/60° cone. The male has a 24° seat, straight metric threads, and a recessed counterbore that matches the tube O.D. used with it. The mating female may be a 24° cone with O-Ring (DKO type), a metric tube fitting, or a universal 24° or 60° cone. DIN couplings are available in light and heavy series. Proper identification is made by measuring both the thread size and the tube O.D. (the heavy series has a smaller tube O.D. than the light series, but a thicker wall section).

A metric standpipe assembly consists of three components assembled onto a male fitting: a standpipe, a bite sleeve, and a metric nut. The metric nut is fitted onto the standpipe, followed by the bite sleeve. For DIN light series assemblies, a DIN light metric nut is used. For DIN heavy series assemblies, a DIN heavy metric nut is used. The bite sleeve and standpipe are selected according to the tube outer diameter (O.D.).
