In hydraulic systems, Code 61 and Code 62 split flange head adapters are single components that serve as the central piece around which two split flange halves are attached. These adapters have a flat, smooth surface that fits perfectly with the two-part split flange, creating a secure, leak-proof connection. Code 61 adapters are designed for lower pressure applications up to 3000 psi, while Code 62 adapters are built for higher pressures up to 6000 psi. The split flange halves clamp around the adapter using bolts, ensuring a firm, reliable seal for hydraulic lines. Select the shape of Flange Head you need.
