What kind of joint is typically used to connect hydraulic hoses?

The use of a swivel joint to connect hydraulic hoses is crucial due to its ability to accommodate angular movement and rotational motion without causing damage to the hoses or the fittings. This flexibility is essential in hydraulic systems where movement occurs frequently, such as in mobile machinery and equipment. A swivel joint allows the hoses to pivot and rotate, reducing stress and wear on the hoses and preventing leaks that could arise from misalignment or chafing.

In contrast, flanged joints are typically used for fixed connections and may not accommodate the necessary movement without creating a risk of hose failure. Screwed joints, while effective in many applications, do not provide the flexibility needed for hydraulic hoses subject to movement. Welded joints create a permanent connection that is not suitable for applications requiring disassembly or flexibility. Thus, the unique characteristics of a swivel joint make it the ideal choice for connecting hydraulic hoses in dynamic environments.
