Alfagomma A-MTN Nuts are straight, carbon steel nuts designed to be used with DIN 24° Heavy Series fittings. These nuts are an essential part of the hose fitting assembly, ensuring a secure connection between hoses and fittings. Ferrules are metal sleeves that help to hold the hose tightly against the fitting, creating a leak-proof seal. The primary difference between two-piece and one-piece fittings is that two-piece fittings consist of separate components (like the nut and ferrule), making them easier to replace or maintain, while one-piece fittings are a single unit that requires complete replacement if damaged. The A-MTN Nuts, when used in conjunction with other A Series fittings, provide a reliable and strong connection for wire and textile braided hoses, thermoplastic hoses, Flexor 4, PTFE hoses, and Alfabiotech hoses of various sizes. This ensures optimal performance in fluid and hydraulic systems.
