Alfagomma A Series Ferrules and Two-Piece Fittings are key components used to create secure, durable connections in hydraulic and pneumatic systems. Ferrules are metal inserts that fit around the end of a hose to compress it, creating a tight seal between the hose and its fitting to prevent leaks. The A Series is a two-piece fitting system, where the ferrule and the insert are separate, providing flexibility and ensuring a custom fit for various hoses like wire and textile braided, thermoplastic, Flexor 4, and PTFE hoses ranging from ³⁄₁₆" to 2" in diameter. These fittings are ideal for high-pressure applications and are used with Alfabiotech 3000 and 4000 hoses in specific sizes. The main difference between two-piece and one-piece fittings is that two-piece fittings allow for the ferrule and insert to be assembled separately, making them more versatile and easier to install, while one-piece fittings come pre-assembled for convenience. This two-piece design is essential for ensuring leak-free, high-performance hose connections.
