The Alfagomma A-FM9H Two-Piece Fittings are designed for heavy-duty applications requiring a 90-degree bend. Made of durable carbon steel, these fittings feature a hose end with a 90° metric O-ring female swivel and a 24° seat, ideal for use with DIN 3865 heavy-duty DIN tubes. They are compatible with a wide range of hoses, including wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and Alfabiotech 3000 and 4000 hoses, sized from ³⁄₁₆" to 2" in diameter. Ferrules are essential components that secure the hose to the fitting, ensuring a leak-proof connection. The key difference between two-piece and one-piece fittings lies in their design: two-piece fittings consist of separate parts, offering easier maintenance and part replacement, while one-piece fittings are a single solid unit. Two-piece fittings are versatile and often preferred for their flexibility and ease of maintenance in industrial settings.
