SAE Flanges are connecting devices attached to hydraulic systems to give room for pipes, tubes, or hoses. These flanges are designed using various sizes for the pipes and other connecting devices. There are different hydraulic systems with requirements in terms of sizes, material, pressure series, etc. hence, it is very important to note the size recommendation before assembling a connection. SAE Flanges are also known as Code 61 and Code 62. While these are referring to the same component, they have a major difference in terms of pressure series. The Code 61 flange is designed to fit in systems requiring 3000 PSI and the Code 62 works perfectly with systems using 6000 PSI.

While talking about the SAE flat and groove face, we can’t but mention SAE Flanges because they are important components of the flange. When buying an SAE Flange, the package comes with different components which are vital to the connection. The complete set SAE Flange has five major component units. The cap screws, flat face, o-ring groove, spring washers, and o-ring face. The face of the SAE Flange has four holes and this is where the screws, cap, and washers will fit in. These components are used to drive and seal in the connection. Hence, ensuring it is secure and leak-proof. The o-ring groove is a rubber-like material and this serves as the seal between the flange faces. The o-ring face and flat side are the flange faces and the o-ring groove is placed between them.
