The Alfagomma Z-C629 Two-Piece Fittings are 90-degree, carbon steel hose end fittings designed to connect with an O-ring flange (SAE J518 Code 62) in high-pressure systems. These fittings are part of the Z Series, specially designed for use with Alfatech 6000 (AT6K) hoses in the 2" size. As two-piece fittings, they consist of separate parts that interlock, making them easy to maintain and repair if needed. Ferrules are small metal rings that secure the hose to the fitting, creating a reliable, leak-free connection. The key difference between two-piece and one-piece fittings is that two-piece fittings can be disassembled for service, while one-piece fittings are permanently assembled. The Z-C629 fittings require both internal and external skiving, a process where the hose is prepared to fit the fitting securely. These fittings also need a ZF1 Interlock ferrule for optimal performance, ensuring a durable and efficient seal in demanding applications.
