The Alfagomma A-FM4L Two-Piece Fittings are 45-degree, carbon steel hose end fittings designed for connecting hoses to metric O-ring female swivel connections with a 24° seat, used with DIN 3865 light duty DIN tubes. These fittings are part of the A Series and are suitable for wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and smaller ID spiral wire reinforced hoses, ranging from ³⁄₁₆" to 2" in diameter. Ferrules are small, durable components that secure the hose to the fitting, ensuring a leak-free and stable connection. The difference between two-piece and one-piece fittings lies in their design: two-piece fittings consist of separate parts, offering the benefit of flexibility and ease of maintenance (e.g., replacing a worn part), while one-piece fittings are a single, fixed unit. The two-piece design is ideal for various applications, providing long-lasting, reliable performance for fluid power systems.
