The Alfagomma A-C629 Two-Piece Fittings are 90-degree carbon steel hose fittings designed for durable, leak-proof connections in industrial fluid power systems. These fittings feature an O-ring flange that complies with SAE J518 Code 62, ensuring a secure and high-pressure seal. Ferrules are metal inserts that help secure the hose to the fitting by compressing it tightly, creating a strong, leak-resistant connection. The difference between two-piece and one-piece fittings is that two-piece fittings consist of separate components, such as the fitting and ferrule, allowing for easier maintenance, repair, and customization. In contrast, one-piece fittings are pre-assembled for quicker installation but offer less flexibility. The A-C629 Two-Piece Fittings are compatible with wire and textile braided hoses, thermoplastic hoses, Flexor 4, and PTFE hoses, as well as Alfabiotech 3000 and 4000 hoses in sizes ranging from ³⁄₁₆" to 2" ID, offering versatile and reliable solutions for a wide range of fluid handling applications.
