3. Key Components & Features - Split Flange Pair, O-Ring, Retaining Groove, Bolts

When assembling SAE flanges, understanding their key components is instrumental in achieving a reliable connection. A split flange pair consists of two components: the male and female halves, which fit together to create a secure joint. The O-ring is another crucial feature, designed to provide a tight seal that prevents fluid leakage between the flanges. Selecting the proper O-ring material is important, as it must withstand the operational environment, including temperature and fluid compatibility. Furthermore, a retaining groove is often incorporated into the flange design, ensuring that the O-ring remains securely positioned during assembly and operation.

Bolts serve as the final component, allowing for the secure fastening of flange pairs. It is essential to select the right bolts, considering factors such as length, diameter, and material properties. Using the wrong bolts can lead to inadequate sealing or the potential for flanges to disengage under pressure. Thus, every component plays a vital role in ensuring the reliability and efficiency of SAE flanges. Understanding these key features allows manufacturers and maintenance personnel to make informed decisions when selecting and installing flanges in their systems.
