What is the difference between 2C9.2D9 90° Elbow Reducer Tube Adaptor With Swivel Nut and 3C.3D Straight Tube Adapters With Swivel Nut?

With the rapid development of modern industrial technology, pipe connection technology is increasingly used in all walks of life. Among them, 2C9.2D9 90° Elbow Reducer Tube Adaptor With Swivel Nut and 3C.3D Straight Tube Adapters With Swivel Nut are two commonly used pipe fittings, each with its own characteristics. This article will introduce the differences between the two in detail.

1. Structural design and functional features

2C9.2D9 90° elbow pipe fitting: This pipe fitting adopts a 90° elbow design, which can realize the conversion of different specifications of internal and external threads with a rotating nut, and flexibly adjust the connection angle. It is suitable for scenarios where the direction of the pipeline needs to be changed, such as the bend connection in the hydraulic system, which can effectively reduce the risk of damage to the pipeline due to direct bending.
3C.3D straight pipe joint: Unlike 2C9.2D9, 3C.3D straight pipe joint adopts a straight line design and is also equipped with a rotating nut. It is mainly used to achieve direct connection between two pipes of the same diameter. In scenarios where there is no need to change the direction of the pipeline, such as straight conveying pipelines, 3C.3D straight pipe joints provide a simpler and more direct connection solution.

2. Performance parameters

Both pipe joints have good performance parameters, such as working pressure, working temperature range, etc. Among them, the working pressure range of 2C9.2D9 90° elbow pipe joint is wide, and the working pressure of some models such as 2C9-12W can reach 500bar, while the working pressure of 3C.3D straight pipe joint is also similar to it, which can meet the needs of various industrial applications.
