The Alfagomma A-C612 Two-Piece Fittings are 22-degree, carbon steel hose fittings designed to securely connect hoses to equipment with an O-ring flange that meets SAE J518 Code 61 standards. These fittings utilize a two-piece design, which includes a ferrule—a metal or plastic component that compresses the hose onto the fitting, creating a tight, leak-proof seal. The key difference between two-piece and one-piece fittings is that two-piece fittings consist of separate components (the ferrule and fitting body), offering more flexibility during installation and replacement. In contrast, one-piece fittings are pre-assembled for quicker installation but offer less flexibility. The A-C612 fitting is compatible with wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and Alfabiotech hoses, ranging from ³⁄₁₆" to 2" in diameter, including Alfabiotech 3000 (1 ¼" and 1 ½") and Alfabiotech 4000 (³⁄₈" to 1 ¼") hoses. This fitting ensures a reliable, secure connection for high-pressure systems in various industrial applications, offering long-lasting performance and durability.
