The Alfagomma A-FJIS Two-Piece Fittings are high-quality, straight, carbon steel hose ends designed to connect to JIS (Japanese Industrial Standard) Female Swivel fittings with a 30° seat, specifically following the B 8363 Type F standard. These fittings are part of a two-piece system, which consists of the hose end and a ferrule, a small metal ring that helps create a strong, leak-proof seal by securing the hose to the fitting. Ferrules are crucial in ensuring the fitting remains firmly attached under high-pressure conditions. The difference between two-piece and one-piece fittings is that two-piece fittings allow for easier maintenance and replacement of individual components, while one-piece fittings are solid and require complete replacement if any part becomes damaged. The A Series Two-Piece Fittings are compatible with various hoses, including wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and Alfabiotech hoses, in sizes ranging from ³⁄₁₆" to 2". These fittings are ideal for applications that demand durable, secure, and leak-proof connections in fluid power systems.
