1 Scope

This part of GB/T 9065 specifies the basis for the design and performance of a 60° tapered hose joint made of carbon steel (see Figure 1 for typical examples).

This requirement and size requirements.

This section applies to hoses with a nominal inner diameter of 5 mm to 51 mm (in accordance with the nominal hose inner diameter of GB/T 2351).

Note. If other materials are used, the supply and demand sides shall negotiate.

Explanation.

1---Hose connector;

2---O-shaped sealing ring;

3---nut;

4---straight stud end connector body (in accordance with ISO 8434-6);

5--- Oil port (conforming to GB/T 2878.1).
