The Alfagomma A-FKOS Two-Piece Fittings are straight, carbon steel hose ends designed to connect with Komatsu Female fittings. These fittings are part of a two-piece system, which means they consist of two main parts: the hose end and a ferrule. Ferrules are small, metal rings that are used to secure the hose onto the fitting, ensuring a tight, leak-proof seal. This two-piece design makes it easier to replace individual components, whereas one-piece fittings are solid and require complete replacement if damaged. These fittings are suitable for a wide range of hoses, including wire and textile braided hoses, thermoplastic hoses, Flexor 4, and PTFE hoses in sizes from ³⁄₁₆" to 2" and Alfabiotech hoses from ³⁄₈" to 1 ¼". The two-piece A Series Fittings provide flexibility and durability, offering strong, reliable connections for high-pressure hydraulic systems, including those in heavy machinery and industrial applications.
