BS ISO 7319:2021 pdf free.Aerospace – Fluid systems – Interface of 24° cone metric couplings.
Tb is document defines the geometry of the interface of removable 24° cone couplings for fluid systems in aircraft. The connection with the pipe of each one of the connecting elements can be of different design.
This document specifies the dimensions which allow the interchangeability of the male and female elements and of the nut used for the connection.
The dimensions define the maximum volume of the male fitting.

4 Coupling assembly and sealing principle
The coupling comprises three elements as follows.
a) A female element including a frustum with a cone angle equal to 24°, with which the male element comes into contact to provide sealing. The contact line is a circle with a theoretical diameter, E.
b) A male element, included inside a shell composed of two frustums connected by a spherical section with which the female element comes into contact to provide sealing. The contact line is a circle with a theoretical diameter, E.
c) A nut allowing assembly of the male and female elements of the coupling.
5 Dimensions
The dimensions shall be as shown in Figure 1 and given in Table 1.BS ISO 7319 pdf free download.
