Introduction to hydraulic joint knowledge

Hydraulic joints are divided into hose joints and transition joints; Hose joints are held in place at the ends of the hydraulic hose. The connection between the hose joint and the component oil port usually requires a transition joint. The transition joint is between the hard pipe joint and the oil port component. It plays a transitional role in the joint, or directly serves as a part of the hard pipe joint (so many manufacturers directly classify the transition joint into the hard pipe joint part);

There are many types of transition joints, and there are many brands, such as Parker, Eaton, etc. Each manufacturer also has different naming rules for joints; Eaton acquired the domestic brand Yonghua, but the naming rules for joints still follow Yonghua. This time we will introduce hydraulic joints based on Eaton’s naming rules; this time we will specifically introduce two types of transition joints:

That is 5X-X-X: external thread/fixed internal thread,

6X-X-X: Over-board connector.

Let’s introduce the naming rules:

1. Numbering rules for corner bend transition joints:

Angle bend transition joint code: Add "4" after the straight transition joint model to indicate a 45° bend transition joint, and add "9" after the straight transition joint model to indicate a 90° bend transition joint. Such as 1BG9-04OG, 1JT4-08-06SP, etc.
