The Alfagomma A-FBO4 Two-Piece Fittings are designed to connect hoses to BSP (British Standard Pipe) O-ring female swivel 60° cone connections at a 45-degree angle. Made from carbon steel, these fittings consist of two parts: the hose end and a separate O-ring female swivel. The ferrules, small cylindrical rings, are used to secure the hose to the fitting, ensuring a tight seal that prevents leaks under pressure. The key difference between two-piece and one-piece fittings is that two-piece fittings allow for easier maintenance, as each component can be replaced individually, while one-piece fittings are a single unit that cannot be separated. The A-FBO4 fittings are suitable for use with wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and smaller ID spiral wire reinforced hoses, providing a reliable and high-performance solution for fluid systems.
