The Alfagomma A-KF90 Two-Piece Fittings are designed for connecting hoses to Komatsu 90° O-ring flanges in high-pressure hydraulic systems. Made from durable carbon steel, these fittings are ideal for situations where a 90-degree bend is necessary for efficient hose routing. The fitting consists of two components: the hose end and the ferrule. Ferrules are metal rings used to secure the hose to the fitting, providing a tight, leak-free connection. Two-piece fittings, like these, are beneficial because individual parts can be replaced as needed, whereas one-piece fittings require the entire assembly to be replaced if damaged. These fittings are compatible with wire and textile braided hoses, thermoplastic hoses, Flexor 4, and PTFE hoses in sizes ranging from ³⁄₁₆" to 2" and Alfabiotech hoses from ³⁄₈" to 1 ¼", making them versatile for use in various industrial machinery and equipment applications.
