The Alfagomma X-C624 Two-Piece Fittings are 45-degree carbon steel hose fittings designed to connect hoses to an O-ring flange with a SAE J518 Code 62 standard. These fittings are part of the X Series and are designed for spiral wire reinforced hoses, providing a secure and flexible connection in high-pressure applications. Ferrules are metal rings used to ensure a tight, leak-proof connection between the hose and fitting. The main difference between two-piece and one-piece fittings is that two-piece fittings offer more flexibility since they can be assembled and disassembled, while one-piece fittings are permanently attached. The X-C624 fittings require both internal and external skiving (trimming the hose ends) and must use either XF1 or XF2 Interlock ferrules to function properly, ensuring optimal performance and durability in demanding conditions.
